5.5.1 About position control
●
In position control, speed commands, which are calculated to eliminate the difference between
the command pulse (parameter setting) and the estimated feedback pulse, are output to rotate
the motor.
●
This inverter can perform simple positioning by contact input or position control by simple pulse
input to the inverter.
