Analog inputs (X3)

The servo amplifier is fitted with two programmable differential inputs for analog
setpoints. AGND (X3/7) must always be joined to the GND of the controls as a ground
reference.

Analog-In 1 input (terminals X3/3-4)
Differential input voltage max. ± 10 V, resolution 14-bit, scalable.
Standard setting : speed setpoint
Analog-In 2 input (terminals X3/5-6)
Differential input voltage max. ± 10 V, resolution 12-bit, scalable.
Standard setting : torque setpoint
Application examples for setpoint input Analog-In 2:

Defining 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 X3/3-4 or X3/5-6
respectively, or change the ROTATION DIRECTION parameter in the "Speed controller"
screen page.
