4 CHAPTER 1 FUNCTIONS AND CONFIGURATION 1.1 Overview This Specification explains the full closed control compatible product that imports a position F/B signal from an external encoder, such as a linear scale, to the MR-J2S-A servo amplifier. For the items that are not described in this Specification, refer to the MELSERVO-J2-Super Series Full Closed Control Compatible Instruction Manual and the MELSERVO-J2S-A Specifications and Installation Guide and Instruction Manual. [Servo amplifier] [Items changed from those of the standard model] 1) The A/B/Z differential input I/F unit MR-J2S-CLP01 or Mitsubishi serial interface compatible linear scale is used to detect the position F/B signal of an external encoder such as a linear scale. 2) In addition to the full closed control that feeds back the position signal of the external encoder, dual F/B control that feeds back a signal composed of the external encoder's position F/B signal and the motor position F/B signal has been added as an extended function. 3) Function to switch pulse output between the closed encoder and motor end encoder [Functions deleted from the standard model] 1) Speed/torque control 2) Absolute position detection function 3) Control switching mode 4) Motor-less operation (test operation) 1.2 Control Block Diagram A full closed control block diagram is shown below.

When semi closed control is selected, control is always performed on the basis of the position data of the motor end encoder (independently of whether the motor is at a stop or running). When the full closed function in parameter No. 86 is valid, dual F/B control in which the motor F/B signal and linear scale F/B signal are combined by the dual F/B filter in parameter No. 97 is performed. In this case, full closed control is performed when the motor is at a stop, and semi closed control is performed when the motor is operating to improve control performance. When 1000 is set as the filter value of parameter No. 97, full closed control is always performed. -4-

6 1.5 System Configuration (1) When A/B/Z differential input I/F unit (MR-J2S-CLP01) is used The A/B/Z differential input I/F unit (MR-J2S-CLP01) converts external ABZ phase pulses into a position feedback signal that can be used for serial communication. Full closed control is enabled by connecting the output of the ABZ differential input I/F unit to the servo amplifier encoder connector. Note: When the MR-J2S-CLP01 is used, a linear scale without Z phase (rotary encoder) cannot be connected. Use a linear scale that has the Z phase.

14 4.2 Home Position Return Operation (1) About controller setting Make setting in the controller after conversion into the motor end unit. The command unit issued from the controller depends on the resolution of the motor end. (2) Precautions for home position return 1) General precautions Home position returns are all performed according to the closed end data. It is irrelevant to the Z phase position of the motor end. In the case of the linear scale, the home position (reference mark) of the linear scale must exist in the home position return direction. The dog should be installed 1/2 or more revolutions of the semi-closed end motor before the reference mark. Example of incremental linear scale Allowed range: A home position return can be made when it is started from within this range. Disallowed range: A home position return cannot be made if it is started from within this range. To execute a home position return securely, make provisions, e.g. move the axis to Limit 1 by JOG operation. Dog Home position Limit 1 Limit 2 return direction Home position (reference mark) of linear scale 2) About Z-phase output of absolute linear scale ( Serial I/F (ABS)) When an absolute linear scale is used, the home position return position is as shown below. Virtual Z phase is created per semi-closed end revolution. Home position of linear scale Incompatible with the absolute position detection function. (The description applies to the case where the absolute linear scale is used in the INC system.) 3) About Z-phase output of incremental linear scale ( Serial I/F, general-purpose pulse output (INC)) When an incremental linear scale is used, the Z phase output from the servo amplifier is provided in the home position (reference mark) of the linear scale. Do not set more than one home position (reference mark). Z phase output cannot be executed when there is no home position (reference mark). Z phase is output in the home position (reference mark) of the linear scale. Precautions for the case when the axis passes through the home position (reference mark) Inherently, the signal ON region of the home position (reference mark) has some degree of width. B A Home position signal B is recognized as ON position. A is recognized as ON position. Since the signal ON position changes depending on the home position passing direction, always start a home position return in the same direction when it is desired to stop the axis in the same home position return completion position every time. -14-

15 4.3 Functions For the functions that are not described below, refer to the MELSERVO-J2-Super Series Full Closed Control Compatible Instruction Manual. For parameter number compatibility, refer to the Table Model-by-Model Parameter Compatibility List since the parameter number compatibility differs from that of the MR-J2S-B-PY Test operation Test operation can be performed using the Servo Configuration software, which runs on the personal computer, and the servo amplifier. Test operation can also be performed similarly using the amplifier front pushbuttons. The full closed control compatible amplifier cannot use motor-less operation. Function Item Usability Remarks Test operation JOG operation Positioning operation Program operation DO forced output Motor-less operation Usable Usable Usable Usable Unusable Performed by the feedback of the motor encoder. It is irrelevant to the full closed encoder. In a semi closed control/full closed control state, operation is performed in the control mode states as set in parameter No. 86, No. 97. When full closed function switching is valid (semi/full switching), semi closed control is always valid. Same as the standard servo function. Not supported Semi/full closed control switching operation Using the external DI signal, semi closed or full closed control can be selected for operation. Using the parameter, pre-assign the full closed selection (FCS) function device to any DI signal. When the full closed selection signal is changed to on or off, the droop pulses are cleared unconditionally and closed loop control switching is executed. This switching must be executed during a servo motor stop. When switching is performed between semi closed and full closed, the machine position and current position do not match since the current position before switching and the current position after switching have a discontinuous position relationship. Note that this switching cannot be used for absolute positioning, etc. Position command and servo motor speed Full closed selection (FCS) Full closed controlling (FCC) (Semi closed control) (Full closed control) (Semi closed control) Within 15ms Droop pulse clearing and closed loop switching processing are executed. Within 15ms (Application example) When only the fixed-pitch stock feed section is full-closed controlled as in a roll feeder. -15-

16 4.4 About the Servo Configuration Software When current version of Servo Configuration software (MRZJW3-SETUP111E to -SETUP151E S/W: E1 version) is used The following indicates how to check whether the full closed-related parameter settings are normal or not and whether the servo motor and full closed encoders operate normally or not. Select "MR-J2S-A" in the system setting of the Servo Configuration software. Opening the batch monitor screen displays the following screen. 1) 3) 2) 4) 5) 6) 7) (1) Explanation of display items The following table indicates the display items that are related to the servo motor and full closed encoders. Symbol Name Explanation 1) Cumulative feedback pulse Feedback pulses from the servo motor encoder are counted and displayed. Click "Clear" to reset the value to 0. Command pulse frequency Position command inputs from the command controller are counted and 2) displayed. Click "Clear" to reset the value to 0. 3) Within-one-revolution position The within-one-revolution position of the servo motor encoder is displayed. 4) ABS counter The multi-revolution counter of the servo motor encoder is displayed. The value is incremented or decremented by 1 per servo motor revolution.

Caution: The name does not Click "Clear" to reset the value to 0. match what is monitored. 6) 7) Servo motor speed ( read as Within-full-one-revolution position) Caution: The name does not match what is monitored. Droop pulse( read as Full ABS counter) Caution: The name does not match what is monitored. The within-one-revolution position of the full closed encoder is displayed. In the case of an INC linear scale, the Z-phase counter is displayed. The value is counted up from 0 relative to the home position (reference mark). The value is displayed in the pulse unit of the closed encoder. In the case of an ABS linear scale, the virtual within-one-revolution position (equivalent to lower 17 bits of the conversion result of 32-bit absolute position data into the motor end unit, 0 to ) is displayed. The multi-revolution counter (number of revolutions from home position) of the full closed encoder is displayed. In the case of an ABS linear scale, the virtual multi-revolution counter (equivalent to lower 15 bits of the conversion result of 32-bit absolute position data into the motor end unit, 0 to ) is displayed. Since the absolute position function is invalid, this model has nothing to do with the absolute home position. -16-
