3 Compact, Easy-to-Use, Inverter for Small-Sized Machines! The wide range of functions of the VF-nC1 meets various users needs, from simple speed control to steady torque at low speed. The vertical contact-type main circuit terminal board and captive screws also ensure easy wiring. Easy to Wire and Install POINT This is a composite photograph. Like most internal power distribution and control devices, the VF-nC1 has a vertical main circuit terminal board for smoother installation in switchboards. Wiring set-up is further improved by the use of captive screws on the main circuit terminal board. VF-nC1 inverters may also be installed side by side to save space. POINT Easy to Select Approval pending Approval pending Approval pending n General-purpose Toshiba inverters have been developed for "Compliance with Global Standards." The three main series: the three-phase 2V, single-phase 2V and single-phase 1V series, comply with major international standards in addition, several series of European models with a built-in EMI noise filter are also available. All of them have a wide range of functions. Easy to Set Up and Operate POINT Contents min 1 Even novice inverter users can operate the VF-nC1 without difficulty by using the RUN and STOP keys and the frequency adjusting knob on the operation panel. The design also allows most functions be controlled from the input terminals. A wizard function helps users with complicated settings. Other functions, which allow easy operation of the VF-nC1, include a vector control function (which improves the torque characteristic), a PI control function (useful for fans and pumps), and a 15-speed preset function.

12 To users of our inverters When studying how to use our inverters Notes Leakage current The amount of leakage current could increase to some extent, depending on the way the inverter is grounded. To prevent current leakage: (1) Use an ELCB free of higher harmonic waves. (2) When connecting multiple inverters to the same ELCB, use an ELCB with high current sensitivity. (3) Connect the inverter to a motor, using a cable as short as possible. Radio interference This inverter could cause interference with nearby audio systems. If interference occurs, its influence can be reduced by installing a noise filter (optional) on the primary side of the inverter or by shielding the cable connecting the inverter to a motor with a conduit, etc. For further information, please contact your nearest Toshiba dealer. Power factor improvement capacitors Do not install a power factor improvement capacitors on the input or output side of the inverter. Installing a power factor improvement capacitor on the input or output side causes current containing harmonic components to flow into the capacitor, adversely affecting the capacitor itself or causing the inverter to trip. To improve the power factor, install an input AC reactor or a DC reactor (optional) on the primary side of the inverter. Installation of input AC reactors Standard replacement intervals of main parts The table below lists standard component replacement intervals under normal operating conditions (i.e., average year round ambient temperature of 3 C, load ratio of 8% or less, average operation time of 12 hours/day). The replacement intervals do not indicates the service life of each component, but the number of years beyond which the failure rate of a component used without being replaced increases shapely because of deterioration and wear.

Note: The service life of each component greatly varies with its usage environment. Selecting the capacity (model) of the inverter Selection Capacity Refer to the applicable motor capacities listed in the standard specifications. When driving a high-pole motor, special motor, or multiple motors in parallel, select such an inverter that the sum of the motor rated current multiplied by to 1.1 is less than the inverter's rated output current value. Acceleration/deceleration times The actual acceleration and deceleration times of a motor driven by an inverter are determined by the torque and moment of inertia of the load, and can be calculated by the following equations. The acceleration and deceleration times of an inverter can be set individually. In any case, however, they should be set longer than their respective values determined by the following equations. Acceleration time Deceleration time Conditions JM : Moment of inertia of motorkgm 2 JL : Moment of inertia of load (converted into value on motor shaft)kgm 2 N : Difference in rotating speed between before and after acc. or dce.min 1 TL Load torquenm TM Motor rated torque NmV/f control Motor rated torque NmVector operation control TB Motor rated torque.2nm When a braking resistor or a braking resistor unit is used: Motor rated torque.8-1.nm Allowable torque characteristics When a standard motor is combined with an inverter to perform variable speed operation, the motor temperature rises slightly higher than it normal does during commercial power supply operation. This is because the inverter output voltage has a sinusoidal (approximate) PWM waveform. In addition, the coking becomes less effective at low speed, so the torque must be reduced according to the frequency. When constant-torque operation must be performed at low speeds, use a Toshiba VF motor designed specifically for use with inverters. [An example of V/f control at a base frequency of 6Hz] Torque (%) (See Note 1.) Maximum torque Allowable torque Output frequency (Hz) Note 1. 1% torque is based on the rotating speed of a motor operated at 6Hz. Starting torque lowers to some extent if the motor runs on commercial power. So, check the characteristic of the machine to drive. Note 2. The allowable torque at a base frequency of 5Hz can be calculated approximately by multiplying the allowable torque at 6Hz by.8. Starting characteristics When a motor is driven by an inverter, its operation is restricted by the inverter's overload current rating, so the starting characteristic is different from those obtained from commercial power supply operation. Although the starting torque is smaller with an inverter than with the commercial power supply, a high starting torque can be produced at low speeds by adjusting the V/f pattern toque boost amount. (15% max., though this rate varies with the motor characteristics.) When a larger starting torque is necessary, select an inverter with a larger capacity and examine the possibility of increasing the motor capacity.
