Analog setpoint 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
Analog input (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.
