Parameter Descriptions
7-94 Position PI Feedback Scale Numerator
Range: Function:
between the motor and the feedback device
when the feedback device is not mounted
on the motor shaft.
Encoder revolutions =
× Motor revolutions
7-95 Position PI Feebback Scale Denominator
Range: Function:
NOTICE
1 [-2000000000 -
*
2000000000]
This parameter is only available
with software version 48.XX.
See parameter 7-94 Position PI
Feedback Scale Numerator.
7-97 Position PI Maximum Speed Above Master
Range: Function:
NOTICE
100 RPM [0 - 65000
*
RPM]
This parameter is only available
with software version 48.XX.
Enter the value by which the follower
speed is allowed to exceed the actual
master speed. Valid only in synchroni-
zation mode.
7-98 Position PI Feed Forward Factor
Range: Function:
NOTICE
98 % [0 - 110 %]
*
This parameter is only available with
software version 48.XX.
Enter the amount by which the speed
reference calculated by the profile generator
is allowed to bypass the position PI
controller.
7-99 Position PI Minimum Ramp Time
Range: Function:
NOTICE
0.01 s [0.000 -
*
3600 s]
This parameter is only available with
software version 48.XX.
Enter the shortest ramp time for the output
of the Position PI controller. Use this
parameter to limit acceleration when
correcting large position deviations, for
example when starting synchronization with
a running master or after recovering from
an overload situation during positioning.
