1)
All rated values are based on an power supply voltage of 400 V/50 Hz, a DC link voltage of 640 V, a control
voltage of 24 V and a surrounding temperature of 40 °C and the switching frequency specified.
2)
The input current must be reduced between 40 °C and 55 °C, refer to correction values at changed operation
conditions,
Z Correction values for the output current of the mains inverter BM50XX, BM51XX – on page 49.
3)
The output voltage is a pulsed direct voltage. The adjusting range is based on the RMS-value of the funda-
mental wave.
4)
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 con-
troller 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 respon-
sible Baumüller sales department, keyword: export restriction).


The range of the output frequency is defined as follows:
PWM frequency Current controller cycle time Range of the output frequency
2 kHz 250 µs 0 - 225 Hz
4 kHz 125 µs 0 - 450 Hz
8 / 16 kHz 62.5 µs 0 - 599 Hz (900 Hz
*)
)

*)
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.
5)
The device draws the rated/peak current at rated supply voltage. The input current must be reduced if power
supply voltage is higher than 400 V and the DC link output power remains constant, refer to
Z Derating: Out-
put current as function of the DC link voltage axis units – on page 55.
6)
The actual possible overload time depends on the preloading of the device and the heat sink temperature
and is detected by the overload monitoring of the device.

Assumption: initial conditions before the overload occurrence: heat sink temperature 40 °C, I = 0 A,
7)
Without loads on the digital outputs and motor brake.
8)
Short-circuit protected for a maximum of 1 minute.
9)
This power rating is the total power rating of both axes.
10)
120 s for BM53XX-SXXX

10 s for cold plate devices BM53XX-CXXX, refer to Z Cooling – as from page 56
11)
The continuously permitted output current must be reduced complying with Z Output frequency-dependent
current derating – on page 74 if the statical output frequency is lower than 15 Hz and the frequency remains
between 0 and 15 Hz for over 5 seconds.
