Overload capability

Load cycle data for Single Motor Modules in chassis format

The base-load current I_L is based on a duty cycle of 110% for 60 s or 150% for 10 s with a duty cycle duration of 300 s.

Low overload

The base-load current I_H is based on a duty cycle of 150% for 60 s or 160% for 10 s with a duty cycle duration of 300 s.

High overload

Derating factors

When the pulse frequency is increased, the derating factor of the output current must be taken into account.

This derating factor must be applied to the currents specified in the technical data.

Derating factor of the output current as a function of the pulse frequency for devices with a rated pulse frequency of 2 kHz

Current derating as a function of the ambient temperature

Note: A derating factor k_T > 1.0 is applicable only in conjunction with "current derating as a function of installation altitude". The rated current data may not be exceeded. For further information see System description.
