Analog Input Pin Number Description
COMMAND J1-22 (+)
J1-23 (-) Analog command signal is a differential type signal to drive
the servo controller.
If the drive is in Velocity Mode configuration, the differential
COMMAND signal is the velocity command.
If the drive is in Torque Mode configuration, the differential
COMMAND signal is the torque or current command.
Separate scale and offset parameters are used for the input,
depending on whether the signal is a velocity command or a
torque current command.
