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.
