Analog inputs (X3)

The servo amplifier is equipped with two differential inputs for analog setpoints which are
programmable. AGND (X3/1) must always be joined to the CNC-GND of the controls as a ground
reference.

Input Analog-In1 (terminals X3/4-5)
Differential input voltage max. ± 10 V, resolution 14-bit, scalable
Standard setting : speed setpoint
Input Analog-In2 (terminals X3/6-7)
Differential input voltage max. ± 10 V, resolution 12-bit, scalable
Standard setting : torque setpoint
Application examples for setpoint input Analog-In2:
—
—
—
Fixing the direction of rotation
Standard setting : clockwise rotation of the motor shaft (looking at the shaft end)
—
—
To reverse the direction of rotation, swap the connections to terminals X3/4-5 and. X3/6-7 or
change the ROT. DIRECTION parameter in the "Speed controller" screen.
