Single-axis drive The single-axis drive (see Fig. -) is used if only single-drive tasks need to be accomplished or if power equalization through several axes is either undesired or not possible. For this purpose, a converter is used that is directly connected to the - phase via an external main contactor, a line filter and a line reactor as necessary. ny regenerative energy is stored in the capacitor module or reduced in the braking resistor... ulti-axis drive up to axes the case of multi-axis drives (see Fig. -) a converter (-) can be combined with inverters (-). The converter rectifies the line voltage and supplies the inverters with direct voltage via the link bus module. The power integrated in the converter further provides the V voltage for the electronics of a maximum of inverters. UTON f more than inverters are connected, the V for the electronics must be provided by an external power. The total rated output currents of the inverters supplied by a converter must not exceed the rated output current of the feeding converter (in the case of SE0-0EP0 only half the rated output current). The regenerative energy generated in one axis can either be used up by the other motors, stored in the capacitor module or reduced in the braking resistor.

These figures are just examples of possible configurations of drives. The necessary individual components have to be clarified according to the specific task. The information and notes required for dimensioning the individual components and the respective order numbers can be found in the atalog. ll the equipment is connected to the line via the line contactor, which is used to separate it from the line if required or in the event of a fault. The size of the line contactor depends on the power rating of the connected converter or inverter. f the line contactor is controlled from the converter, the main contactor checkback time P00 should be set to at least 0 ms. ccording to their response characteristic and to suit the requirements, the line fuses protect the connected cables and also the input rectifier of the unit. The line commutating reactor limits current spikes, reduces harmonics and is necessary for keeping system perturbations to within the limits laid down by VE 00. The external V is used to maintain the communication and diagnostics of the connected-up units even with powered-down line voltage. The following criteria apply regarding dimensioning: current of must be provided for the rectifier unit, and a current of for each inverter connected. When the V is powered up, an increased inrush current will be generated that has to be mastered by the power. No controlled power unit has to be used; the voltage must be between 0 V and 0 V. the case of a single drive and a multi-axis drive without a rectifier unit, a switch is used to energize or de-energize the line contactor. When they are switched off, the drives are not brought to a controlled standstill, but are braked only by the load. the case of a multi-axis drive with a rectifier unit, a pushbutton is used to energize the line contactor. The line contactor is kept energized by means of a lock-type contact connected to the fault signaling relay of the rectifier unit, as long as no fault is detected at the rectifier unit. Operating the OFF switch causes the line contactor to open immediately. The drives are not brought to a controlled standstill, but are braked only by the load.

When the V is connected, the relay closes as long as no fault is present. the event of a fault, the lock of the line contactor is opened, the contactor drops out and the drives coast down. The USS bus is used for the internal communication of the units and only has to be connected if it is required. The digital inputs and outputs and the analog input and output have to be assigned according to the requirements of the drives. UTON: Terminal X0. may not be connected with the external V. The X0 interface of the rectifier unit serves only for permanently connecting the user-friendly OPS operator control panel and for connection to the on-line inverters. Please refer to the relevant operating instructions for the applicable measures and notes for correct operation. The serial interface is used to connect the user-friendly OPS operator control panel or a P. t can be operated either according to the RS or the RS protocol. Please refer to the relevant operating instructions for the applicable measures and notes for correct operation. When a capacitor module is used, the terminals for precharging the capacitors must be connected. The use of an output contactor is purposeful if a motor needs to be electrically isolated from the converter/inverter with the link charged. Use of a line filter is necessary if the radio interference voltages generated by the converters or rectifier units need to be reduced. The Siemens cables described in the catalog should be used for connecting the converter and the motor to each other. The "Safe Stop" option enables the power for the transmission of pulses into the power section to be interrupted by a safety relay. This ensures that the unit will not generate a rotating field in the connected motor. The auxiliary contactor is used to interrupt the self-holding condition of the main contactor in the event of a fault signal. t must be used if the control voltage for line contactor Q is 0 V. The auxiliary contactor is not required if a line contactor with a control voltage of V is used. Used to acquire the motor speed and allows speed-controlled operation with the highest degree of dynamic response and precision.

The converter or rectifier units, or infeed/regenerative feedback unit is connected to the power via the line contactor and disconnected in case of need or in the event of a fault. The system is dimensioned according to the output of the connected converter, rectifier unit or rectifier/regenerative feedback unit. radio interference suppression filter is required whenever the radio interference voltages originating from converters or rectifier units must be reduced according to EN 00-. The line commutating reactor limits current peaks and reduces harmonics. t is also required, among other things, for compliance with the permissible system perturbations according to EN 0 and compliance with the radio interference suppression voltages. The X / control terminals are provided with a connection for ing devices requiring an external V control voltage. Terminals X / on the compact units (inverters) and X / on the chassis units (converter and inverter) allow the output of an isolated digital signal, e.g. to control a main contactor. Function "SFE STOP" on compact inverters and input units (converters and inverters) with option K0 With the "SFE STOP" function, a safety relay can be used to interrupt the power for pulse transmission in the power section. This ensures that the inverter cannot operate the connected motor. On all chassis and compact units of type, a voltage of 0 V 0/0 Hz is required for the fans. The chassis units are connected via X:. and the compact units are connected directly to fan fuses F0 and F0. Siemens G SE0-QX0 (Version E) SOVERT STERRVES ompendium Vector ontrol -

"Safe STOP" function NOTE The "SFE STOP" function of SOVERT STERRVES (also known as "Starting lockout" in SORVE ) satisfies EN 0 0-/N VE 0 Part Section., "evices for switching off and preventing unexpected starting", but does not satisfy Section., ain switch function (isolating from the power ). The main switch function can be performed only by the use of an electrically isolating switching element. The "SFE STOP" function is also suitable for implementing the stop function according to ategory 0 and as defined by EN 0 0- / VE 0 Part, Section... The requirements for the behavior of the control functions in the case of a fault (EN 00-, Section.) are met by fulfillment of the requirements of EN - acc. to ategory. Purpose of the "SFE STOP" function NOTE Residual risk The SFE STOP function is supplied as standard with SOVERT STERRVES of the compact series of inverter units in sizes to (with the exception of converters and inverters for 0 V to 0 V ). the case of chassis units and ompact PLUS units, this function is obtainable in the form of the K0 option. The "SFE STOP" function prevents unexpected starting from standstill of the connected motor. The "SFE STOP" function should not be activated until after the drive is at standstill, because otherwise no further braking is possible. That is why the drive must be brought to standstill and secured by means of an external machine control. The "SFE STOP" function interrupts the power used to drive the GBT modules. residual risk remains in the event of two faults occurring at the same time. The drive can then turn through a small angle (permanent-field synchronous servomotors, e. g. FT, FK: -pole 0, -pole 0, -pole ; asynchronous motors: in the remanence range max. slot division, or about to ). The "SFE STOP" function does not electrically isolate the equipment and therefore gives not protection from "electric shock". The whole machine must be isolated from the system by opening the main switch (EN 00/.) in the event of production shutdowns or for maintenance, repair and cleaning work on the machine or plant.

20 onfiguration and onnection Examples 0.00 When used with the positively-driven signal contacts of the compact inverter units, the "SFE STOP" function has to be connected to terminal strip X: / (chassis units: terminal strip X: /) in the line contactor circuit or EERGENY OFF circuit. f there is any doubt as to whether the SFE STOP relay is functioning correctly with respect to the operating mode of the machine, the drive concerned must be electrically isolated from the power, e. g. by means of a line contactor. The "SFE STOP" function and the associated mode of operation must not be used again until after the fault has been remedied. NOTE When the "SFE STOP" function is activated, it is possible in some cases for the "Operating" status signal to be generated at the converter/inverter. But the pulses are not released and so the motor cannot turn. hazard is therefore ruled out. From the control, with the aid of heckback SFE STOP (X Pin /; X Pin /), make sure that the SFE STOP function cannot be deactivated in converter statuses other than REY FOR ORTON or REY FOR SWTHNG ON. order that the converter/inverter control recognizes the SFE STOP status and proceeds to process this status in the sequencing control, a binary input of the UV control unit must be activated, thereby generating the OFF command (cf. P...P) and hence a starting lockout. When the OFF command is activated via "SFE STOP", the converter status changes to Starting lockout.

22 onfiguration and onnection Examples 0.00 Operating principle of "SFE STOP" The power to the individual motor windings is controlled by means of the inverter power sections. pulse formation logic drives the GBT power transistors in a rotating-field-oriented pattern. each transistor arm, an optocoupler/fiber optic cable is connected between the control logic and the control amplifier of the power section for potential isolation. s it cannot be ruled out that the inverter electronics will generate a pulse pattern capable of producing a rotating field (without a start command being present), a method was found of safely preventing the pulse pattern from reaching the ignition and control inputs of the GBTs. The "SFE STOP" TVE function implements an electrical separation (interrupt) between the power and the driver electronics of the GBT inverter, thereby preventing the motor from turning. The "SFE STOP" function is activated by an external NO contact and is active when the "SFE STOP relay" has dropped out. the event of failure of the "SFE STOP" function, the "SFE STOP" checkback contacts must separate the drive from the power by means of a line contactor or the EERGENY STOP circuit. No rotating-field-oriented operation of the power transistors is possible while the "SFE STOP" function is active. Simultaneous welding of two GBTs is the worst case leading to the residual risk described in the above. NOTE The motor can no longer develop torque while the "SFE STOP" function is activated. Non-self-locking drives must be secured by means of a mechanical brake. The "SFE STOP" function is not suitable for bringing a running motor to a standstill as quickly as possible, because this function turns off the control pulses and so the motor is braked only by the load. dvantage: The "SFE STOP" function makes it unnecessary to provide motor contactors.
