7.2 Speed control (ASR)

When the control mode selection (P012) is set to 00, operation mode becomes a speed control operation mode (ASR mode).

Please drive after setting up the frequency, operation command and each motor constant .

7.3 Position control (APR) (Electronic gear function)

When the control mode selection (P012) is set to 01, operation mode becomes a speed control operation mode (APR mode).

7.3.1 Function outline

This function generates the frequency based on the position command pulse which comes from the pulse train input from the terminal and position feed back pulse which is detected by the motor encoder, and performs the position control operation. It can be used

as synchronous operation of main and sub motor. Also the turn ratio of main and sub motor can be changed by setting up the electronic gear ratio (N/D). (Electronic gear function)

7.3.2 Control mode setting

Inverter at the main motor (master inverter) can be set both as a speed control and position control. Please set up the inverter at the sub motor side (slave inverter) to a position control mode.
