Analog Inputs (X3B)

The servo amplifier is fitted with two programmable differential inputs for analog set-
points. AGND (X3B/13) must always be joined to the GND of the controls as a ground
reference.
Technical characteristics

Analog-In 1 input (terminals X3B/10-9)
Differential input voltage max. ± 10 V, resolution 16 Bit (accuracy 13 Bit), scalable.
Standard setting: speed setpoint
Analog-In 2 input (terminals X3B/12-11)
Differential input voltage max. ± 10 V, resolution 16 Bit (accuracy 13 Bit), scalable.
Standard setting: torque setpoint
Application examples for setpoint input Analog-In 2:
—
—
—
If an input was freshly assigned to a pre-programmed function, then the data set must be
saved in the EEPROM of the servo amplifier and a reset has to be carried out (with the
amplifier setup software for example).
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 X3B/10-9 or
X3B/12-11 respectively, or change the COUNT DIRECTION parameter in the "Feedback"
screen page.
