How to Programme
6.3 Parameters: 4-** Limits/Warnings
6.3.1 4-1* Limits
Use these parameters to adjust warning limits for power.
Warnings are shown on the LCP, can be programmed as
outputs, and can be read out via the serial bus in the
Extended Status Word.

Function:
[ 1.0 - 1000.0 %] This is a true current limit
function.
Function:
Enter the regen power limit. When
the regenerative power exceeds
this limit the display reads Regen
Limit. The signal outputs can be
programmed to produce a status
signal on terminals 27 or 29 and
on relay outputs 01 or 02.
Function:
Enter the active power limit. When
the active power exceeds this limit
the display reads Power Limit. The
signal outputs can be programmed
to produce a status signal on
terminals 27 or 29 and on relay
outputs 01 or 02.
Function:
Select the time-out function. The time-out
function activates when the output frequency
exceeds the deviation limit set in parameter 4-91
Output Frequency Deviation Limit for the time set
