8.16.2 Analog Input
The drive is fitted with differential inputs for analog torque, velocity, or position control. The standard drive offers one
analog input on X21, dual axis drives and drives with built-in option IO or DX offer a second analog input on X22.
Maximum distance for unshielded I/O lines is 3 m inside the cabinet. If the I/O cable leaves the cabinet, it
must be EMC shielded.

Defining the direction of rotation
Standard setting: clockwise rotation of the motor shaft (looking at the shaft end) affected by positive voltage between
terminal (+ ) and terminal (- )
To reverse the direction of rotation, swap the connections to terminals +/- or change parameter AXIS#.DIR in
WorkBench.
