8.2 Derating of output power

Drive controllers of the DGM Modular series have two
integrated PTC resistors as standard which monitor both
the heat sink temperature and the inner temperature. As
soon as a permissible IGBT temperature of 95°C or a
permissible inner temperature of 85°C is exceeded, the
drive controller shuts down.
DGM Modular type drive controllers are designed for an
overload of 150 % for 60 sec. and 200 % for 3 sec.
(every 10 min.).
Reductions in the ability to handle overload and/or its
duration should be taken into account in the following
circumstances:

The respective max. output values can be determined from
the following characteristic curves.
A clocking frequency permanently set too high >4 kHz
(load-dependent).
A permanently increased heat sink temperature,
caused by a blocked air flow or a thermal blockage
(dirty cooling ribs).
Depending on the type of assembly, permanently
excessive ambient temperature.
