Description 

0 

ENABLE  Set to 1 to put the Unidrive in READY mode. (The 

hardware ENABLE must also be present.)  The RUN 
FWD, JOG and RUN REV bits will have no effect 
unless the ENABLE bit is set to 1.  The Unidrive 
outputs are disabled immediately when the ENABLE 
bit is reset to 0, and the motor will coast to stop 

1 RUN 

FWD 

Set to 1 to run the motor in the forwards direction.  
Reset to 0 to decelerate the motor to a controlled 
stop before the Unidrive output stage is disabled 

2 

JOG 

Set to 1 with RUN FWD or RUN REV bit also set to 
jog the motor in the appropriate direction.  The 
Unidrive will ramp the motor to the normal speed or 
stop when the JOG bit is reset to 0, depending on 
the status of the  RUN FWD and RUN REV bits. 

3 RUN 

REV 

Set to 1 to run the motor in the reverse direction.  
When reset to 0, the Unidrive will decelerate the 
motor to stop before the outputs are disabled 

4 

TRIP 

Set to 1 to trip the Unidrive on “tr52”.  The TRIP bit 
must be reset to 0 before the Unidrive can be reset.
