19-14 Motor/encoder gear nominator
Range:
Function:
1
[1...1,000]
If the encoder is mounted on a gear where 5 revolutions of the
motor correspond to 2 revolutions of the encoder, GEAR NUM
should be set to “5” (the number of motor revolutions) and
GEAR DEN should be set to “2” (the number of encoder revo-
lutions). If the encoder is mounted directly on the motor shaft
this parameter setting should remain at “1”.
19-15 Motor/encoder gear denominator
Range:
Function:
1
[1...1,000]
See the description of GEAR NUM. If the encoder is mounted
directly on the motor shaft this parameter setting should remain
at “1”.
19-16 Maximum jog velocity
Range:
Function:
100
ERPM
[1...999,999 ERPM]
The maximum speed allowed while jogging the application is
specified in terms of Encoder Revolutions Per Minute (ERPM).
NB!
This setting must never exceed a value that is approx. 5% lower than the value in
par. 32-80.
19-17 Jog ramp time
Range:
Function:
5,000
ms
[50...100,000 ms]
This parameter specifies both the ramp-up time as well as the
ramp-down time used during jogging. The ramp time is defined
as the time in milliseconds it would take to ramp from standstill
to the maximum allowed velocity 3280.
19-18 Jogl Velocity Scaling
Range:
Function:
0
[0...1]
If 1, the scale velocity will be scaled by MOT ENC GEAR NUM/
DEN
19-19 FFVEL auto-calculation
Option:
Function:
[0]
*
Disabled
[1]
FFVEL enabled
Setting this parameter to “1” will prompt the program to calcu-
late the optimal setting of parameter velocity feed forward.
