7.5 Reversing
Motion
Direction
In order to reverse the motion direction of the drive, the command to the drive needs to be
reversed. In addition, the emulated encoder output polarity needs to be reversed if an external
controller is using the emulated encoder outputs for feedback.
To reverse the command to the drive in Torque or Velocity Modes either change the wiring or
change the parameters:
CmdSrc Setting
Wiring Method Parameter
Method
Analog Command
Swap the analog
command connections
(J4-24 and J4-25)
Change the sign of
CmdGain

Command
PWM Input
Swap the PWM
connections (J4-10 and
J4-11)
Change the sign of
CmdGain
To reverse the command to the drive in Position Modes:
PosCmdSrc Setting
Wiring Method
PosCmdSrc
= AQuadB
Reverse the Ch A input to the drive by swapping J4-19
and J4-20.
PosCmdSrc
= Step-Dir
The Direction command, J4-5, to the drive needs to be
inverted by the user’s controller.
To reverse the
Emulated Encoder Outputs
from the drive:
•
Reverse the Emulated Encoder Outputs if the external control loops use the emulated
encoder outputs for feedback.
•
Swap the CHA and CHA/ emulated encoder outputs (J4-19 and J4-20) going to the
external controller.
