Servo Mode 

 
 

If drive is setup for 

Servo

  ( see 0.48 ) then the drive can be run and checked for  

its’ most basic operation.

 

 

Set  

 
#0.05 = Pad (or 4 )  

so that you can Start/Stop and change speed from front of drive 

 
Recheck motor parameters #0.42, 45 and  0.46 and Max RPM  (# 0.02 ) ,  
Accel Rates #0.03 & 0.04   = 5-15 seconds to 1000rpm  
Hold Mode= #6.08= 0  or 

Off

  

Stop Mode   

rP 

=    Ramp       located at    #6.01 in both Classic & SP 

 
Verify encoder voltage

Unidrive SP 

#3.23      0= 5v    1= 15v                           #3.36     5,8,15v 

 

 

 

 

 

 

 

 

If >5v set #3.39= 0 

Check for proper encoder wiring and operation    
 

Manual rotation of motor shaft clockwise will result in up counting    

 

                                   –if not swap A and /A 

 

Check for correct encoder PPR  

 

 

 

 

   #3.21 

    #3.34 

Unidrive Classic

      

 

       

Unidrive SP 

If correct 

Encoder 

 #3.27=    

 

 

 

  

       #3.29=   

 

¼ Rev  

         =   4096 

 

 

 

     =   16384 

½ Rev  

         =   8192 

 

 

 

     =   32767 

1  Rev  

         =   16384 

 

 

 

     =   65,535 

 
 
You could run Auto Tune 
Auto Tune 

 

#0.40=1  Rotating        #0.40=1  motor rotates upto 2 revs 

 

 

 

 

 

                 #0.40=2  motor rotates upto 2 revs    

       Stator resistance measured in test 2 

                Parameter #3.25 gets updated with motor phasing angle 
 

 

            

 

 

  Enable needs toggled to move beyond 

  

 

( Shaft must be unloaded for rotating Autotune !!! ) 

If motor rotates CCW  reverse  U & V motor leads and repeat 

 
You should be able to run drive from keypad for basic checkout. 
Test by depressing 

GREEN

 Run and Up Arrow to ¼ speed then test 

Stop

 

If ok go to ½ Speed – Stop  then ¾ - Stop  then to Full Max Speed if all OK
