At rated power supply voltage the unit supplies rated / maximum output currents. With input voltages above the rated power supply
voltage the output currents must be reduced at constant output power.

The input current must be reduced between 40 °C and 55 °C. Refer to correction factors at changed operating conditions
8)
The possible overload time at this moment is dependent of the device load and the heat sink temperature. The device load is determined
by the overload monitoring of the device.

The range of the output frequency is based on a stationary operation in the linear range of the PWM, i. e. without overmodulation.
The quality of the generated output voltages depends on the ratio between output frequency and current controller frequency f
I-R
( f
I-R
= 1/cycle time current controller).
The maximum output frequency f
max
, generated with high quality, is calculated as follows:

Furthermore the controller sets an upper limit for the output frequency of 599 Hz (please contact the responsible Baumüller sales de-
partment, keyword: export restriction).
The range of the output frequency is defined as follows:
PWM frequency
Current controller cycle time

900 Hz could be generated by the controller
The device is able to generate output voltages with frequencies between f
max
and 599 Hz and the controller allows that, however the
quality of this voltages cannot be guaranteed.
Typical the devices are marked with the max output frequency at 4 kHz switching frequency: 0 ... 450 kHz.
13)
The permitted output current must be reduced complying with
Output frequency dependent continuous current derating BM5XXX
Output frequency dependent maximum current derating BM56XX
on page 120 if the statical output frequency is lower
than 15 Hz and the frequency remains between 0 and 15 Hz for more than 5 seconds.
14)
The device is available only in cooling type „Z“ and „F“ with standard design (BM56XX-XXX6) or short design (BM56XX-XXX9).
