4.7 Digital and analog inputs and outputs
4.7.1
Analog input (X3)
The servo amplifier has a programmable input for analog setpoints.
AGND (X3/1) must always be joined to the CNC-GND of the controls to provide a ground
reference.
Technical data
— Input voltage max. ± 10 V
— Resolution 1.25 mV
— Ground reference AGND, terminal X3/1
— Input resistance 20 k
W
— Common mode voltage range for both inputs ± 10 V supplementary
— Update rate: 62,5 µs
Input Analog-IN (terminals X3/2-3)
Input voltage max. ± 10 V, 14-bit resolution, scalable
Standard setting: Speed Setpoint
Fixing the direction of rotation
Standard setting: clockwise rotation of the motor shaft (looking at shaft end)
with positive voltage on terminal X3/3 (+ ) against X3/2 ( - )
To reverse the direction of rotation you can swap the connections to terminals X3/2-3 or
change the
DIRECTION parameter in the SPEED screen.
