Function:
Enter the I value. When the motor
HIGH
current exceeds this limit, a bit in the
status word is set. This value can also be
programmed to produce a signal on the
digital output or the relay output.
Function:
Enter the lower reference limit. When the
actual reference drops below this limit, the
display reads Ref . The signal outputs can
LOW
be programmed to produce a status signal
on terminal 27 or 29 and on relay output 01
or 02.
Function:
Use this parameter to set a higher limit for the
reference range.
When the actual reference exceeds this limit,
the display reads Reference High. Warning bit
19 is set in parameter 16-94 Ext. Status Word.
The output relay or the digital output can be
configured to indicate this warning. The LCP
warning indicator light is not turned on when
this parameter set limit is reached.
Function:
[-4999 - 4999 Use this parameter to set a
ProcessCtrlUnit] lower limit for the feedback

range.
When the feedback drops
below this limit, the display
reads Feedback Low. Warning
bit 6 is set in
parameter 16-94 Ext. Status
Word. The output relay or
digital output can be
configured to indicate this
warning. The LCP warning
indicator light does not light
up when this parameter set
limit is reached.
Function:
[-4999 - 4999 Use this parameter to set a
ProcessCtrlUnit] higher limit for the feedback

range.
When the feedback exceeds
this limit, the display reads
Feedback High. Warning bit 5

Bypass Set-up.
Press [Hand On] to start the search for frequency
bands causing resonances. The motor ramps up
according to the ramp set.
