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 .

7.3Position 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).
