Parameter Descriptions
6-26 Terminal 60 Filter Time Constant
Range:
4 4
0.01 s [0.01-10.00 s] Enter time constant.
*
4.7.5 6-8* LCP Potentiometer
The LCP potentiometer can be selected either as Reference
Resource or Relative Reference Resource.
NOTE
In Hand mode the LCP potentiometer functions as local
reference.
6-80 LCP Potmeter Enable
Option:
[0] Disabled
[1] Enable
*
6-81 LCP Potentiometer Low Ref. Value
Range:
0.000 [-4999-4999] Enter low reference value.
*
6-82 LCP Potentiometer High Ref. Value
Range:
50.00 [-4999-4999] Enter high reference value.
*

VLT
Function:
A first-order digital low pass filter time
constant for suppressing electrical noise
in terminal 60. A high time constant
value improves dampening, but also
increases time delay through the filter.
NOTE
This parameter cannot be changed
while motor runs.
Function:
If LCP Potmeter is disabled, [▲] [▼] can adjust
local reference, and Potmeter value does not give
any reference in Auto/Hand mode.
Function:
The scaling value corresponding to 0.
The reference value corresponding to
potentiometer turned fully counter-
clockwise (0 degrees).
Function:
The scaling value corresponding to the
maximum reference feedback value set in
3-03 Maximum Reference.
The reference value corresponding to
potentiometer turned fully clockwise (200
degrees).

Function:
signal at terminal 42 as percentage of
maximum signal value. E.g. if 0 mA (or 0
Hz) is desired at 25% of maximum output
value, program 25%. Scaling values up to
100% can never be higher than
corresponding setting in 6-94 Terminal 42
