1)
All rated values refer to a supply voltage of 230 V (single phase) and accordingly 400 V (3-phase) at 50 Hz,
a control voltage of 24 V and an environmental temperature of 40 °C.
2)
The input current must be reduced be a temperature of 40 °C and 55 °C, see correction factors at modified
environmental conditions,
3)
At the rated supply voltage, the device takes up the rated-/peak-input current. At the input voltage above the
rated supply voltage, the input current must accordingly be reduced at a constant output power, see correc-
tion factors at modified environmental conditions,
4)
The output voltage is a pulsed direct current (DC). The operating range refers to the RMS value of the fun-
damental wave.
5)
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

4 kHz
125 µs

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 Hz.

Current derating see
Frequency-output-dependent current derating
7)
At a DC-link-rated voltage, the device supplies the rated-/maximum-output current. At DC link input voltages
above the rated-supply voltage, the output current must accordingly be reduced at a constant output power,
see correction factors at modified environmental conditions,
8)
The overload time is dependent of the motor current and of the heat sink temperature and is determined by
the Ixt-monitoring of the device.
9)
The continuously permitted output current must be reduced complying with
on page 44, if the statical output frequency is lower than 15 Hz and the frequency remains
between 0 and 15 Hz for over 5 seconds.
10)
The output power must not exceed the limit value of 1.5 kW, it is limited by the controller.
