8.11 Digital and analog inputs and outputs
8.11.1 Analog inputs (X3)
The servo amplifier is fitted with two programmable differential inputs for analog set
-
points. AGND (X3/7) must always be joined to the GND of the controls as a ground
reference.
Technical characteristics
Differential-input voltage max. ± 10 V
Ground reference AGND, terminal X3/7
Input resistance 2.4 kW
Common-mode voltage range for both inputs ± 10 V
Update rate 62,5 µs
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:
adjustable external current limit
reduced-sensitivity input for setting-up/jog operation
pre-control / override
Defining the direction of rotation
Standard setting : clockwise rotation of the motor shaft (looking at the shaft end)
Positive voltage between terminal X3/3 (+ ) and terminal X3/4(-)or
Positive voltage between terminal X3/5 (+ ) and terminal X3/6(-)
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.
