Function:
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".
Function:
See the description of GEAR NUM. If the encoder is mounted
directly on the motor shaft this parameter setting should remain
at "1".
Function:
The maximum speed allowed while jogging the application is
specified in terms of Encoder Revolutions Per Minute (ERPM).
Function:
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.
Function:
If 1, the scale velocity will be scaled by MOT ENC GEAR NUM/
DEN
Function:
Setting this parameter to "1" will prompt the program to calcu-
late the optimal setting of parameter velocity feed forward.
