Bridge B current limit may be increased by this value per cent, provided that you
F
program P061 > 100%. This function is to be found in DCREG4 only.
Such value is applied to the present current limit resulting from the composition
of the values set in all relevant parameters (see parameter C000 and parameter
set P050 ... P062 - in case of internal limit).
If actual overlimit exceeds the value stated in the OVERLOAD CAPABILITY
TABLE, i.e. 150% of the drive rated current for 1m every 10m for Size 1 ... 2A
and lower values for MODULAR.S, then drive overheating alarm (A022) will trip.

F When this time, expressed in seconds, is over, if the drive is still in current
overlimit, the 6:FullOverLimit function is enabled, which is programmed in one of
the configurable digital outputs. Said output is disabled as soon as the drive is
no longer in overlimit mode.

This gain is represented by par. P070 if the digital input configured by setting
one of par. C130 ... C135 to 8:Second ParmSet is open, or it is represented by
par. P076 if this digital input is closed.
