Motor constant relation data
When the control mode selection (P012) is set to 00, operation mode
becomes a speed control operation mode (ASR mode). Relation
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).

H002/H202-H052/H252:
Motor constant relation data
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.
