Analog setpoint inputs (X3)
The servo amplifier is equipped with two differential inputs for analog setpoints which are freely
programmable (with the aid of the macro-language, consult our applications department). AGND
(X3/1) must always be joined to the CNC-GND of the controls as a ground reference.
Technical characteristics
—
Differential-input voltage max.
±
10 V
—
Resolution 1.25 mV
—
Ground reference : AGND, terminal X3/1
—
Input resistance 20 k
Ω
—
Common-mode voltage range for both inputs ± 10 V
Input SW/SETP.1 (terminals X3/4-5)
Differential input voltage max. ± 10 V, resolution 14-bit, scalable
Standard setting : speed setpoint
Input SW/SETP.2 (terminals X3/6-7)
Differential input voltage max. ± 10 V, resolution 12-bit, scalable
Standard setting : torque setpoint
Application examples for setpoint input SW/SETP.2:
—
adjustable external current limit
—
reduced-sensitivity input for setting-up/jog operation
—
pre-control / override
Fixing the direction of rotation
Standard setting : clockwise rotation of the motor shaft (looking at the shaft end)
—
Positive voltage between terminal X3/4 (+ ) and terminal X3/5 ( - ) or
—
Positive voltage between terminal X3/6 (+ ) and terminal X3/7 ( - )
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.
