Motor Current Limitation
DOK-INDRV*-KCU+KSM****-PR01-EN-P
Blowers are not available for Rexroth IndraDrive Mi.
The current limitation makes sure that neither controller nor motor are
damaged by overload, as long as the motor temperature remains below
100 °C. When the housing temperature of 100 °C is exceeded,
overtemperature shutdown takes place.
With a load of more than 200%, the I
temperature of winding and electronic system to the safe working range.
In standstill (turning shaft n < ~60 min
restrictive way, due to the concentration of losses to one phase. For
bigger motors, the continuous torque at standstill can be less than 200%
of the continuous torque at standstill 60 K.
The limitation starts at 100% of thermal drive load (P-0-0141). To have
reserve capacity (e.g. for dynamic processes or increased friction), you
should dimension the drive system with less than 80% of thermal drive
load. You have to check the drive load during initial commissioning.
