All rated values refer to a DC link voltage of 540 V, a control voltage of 24 V and an environmental temperature of 40 °C.
2)

The output voltage is a pulsed DC voltage. The operating range refers to the RMS of the fundamental wave.

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 ZEnviron-
mental temperature– on pag
e 55.
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.
9)
For cooling versions S and A, only.
10)
If UL508C is complied with: max. 4.0 A.
11)
Refer to ZMotor requirements– on page 52.
12)
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 betw
een 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 Range of the output frequency
2 kHz 250 µs 0 - 225 Hz
4 kHz 125 µs 0 - 450 Hz
8 kHz 62.5 µs 0 - 599 Hz (900 Hz

)

900 Hz could be generated by the controller
The device is able to generate output voltage
s 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.

Using internal brake resistors, the continuous brake resistor power is 5 kW.
