Vector Mode
If drive is setup for CL.Vector ( 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 - 0.47 and Max RPM (# 0.02 ) ,
Accel Rates #0.03 & 0.04 = 5-15 seconds to 1000rpm
S-ramp #2.06 = On S-Curvature #2.07 could be increased a bit ( 10 )
Stop Mode
rP
= Ramp located at #6.01 in both Classic & SP
Verify encoder voltage
Unidrive Classic
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 Static ( non-rotating)
#0.40=2
Rotating
( motor will go to 2/3 max speed )
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
