7.2.34 P058: CURRENT LIMIT DECREASE PER CENT
Current limit decrease per cent for both bridges following the configured digital
input closing, as long as one parameter among C130 ... C135 is set to 4:Clim.
Such value is to be applied to the present current limit resulting from the
composition of the values set in all relevant parameters (see parameter C000,
parameter set P050 ... P062 - in case of internal limit - and trimmer hardware
limit (IMAX[T2]) - if any).
7.2.35 P059: RAMP OVER THE CURRENT REFERENCE
This parameter indicates the max. variation of the current reference in a
microsecond; that variation is expressed as a percentage of the max. value
(100%) corresponding to the drive rated current.
This is the same as imposing - to the current reference - a min. rise ramp time
from zero to 100% and a min. fall ramp time from 100% to zero.
The time (expressed in milliseconds) corresponding to a particular value of such
parameter results from the following formula:
. E.g., the range of
this parameter is equal to 0.1 … 10ms with a 0.25ms default value.
7.2.36 P060: BRIDGE A CURRENT OVERLIMIT
Bridge A current limit may be increased by this value per cent, provided that you
program P060 > 100%.
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 current).
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.
