● X391/X392 – position feedback interface
15-pin sub-D socket connector, position feedback to NC system.
● X311/X312 － encoder interface
25-pin sub-D socket connector, connecting with resolver in
servomotor.
● Drift － drift compensation
Implement the drift compensation when the rated speed is zero
(short circuit between terminal 56 and 14).
Adjustment range: -45mV~ +45mV。
● Tachometer
The actual drive speed for +/-10V speed setpoint can be varied in
range 0.6 nrated ~1.8 nrated . It is not necessary for customers to adjust
the tachometer, as it is already calibrated before delivery.
● KP － proportional gain
The proportional gain KP of the speed controller can be set using
potentiometer KP. It is used to optimize the speed dynamic
performance. Adjustment range: 2.5 ~95.
