Limiting the maximum output frequency
The maximum output frequency (
) of the controller is not limited depending on the
switching frequency. Therefore, adapt the maximum output frequency according to our
recommendation:
• At a switching frequency of 4 kHz, for instance, 500 Hz for the maximum output frequency
should not be exceeded.
Carry out further measures:
• If required, deactivate the switching frequency changeover by the heatsink temperature via
.
• If required, ensure that the changeover threshold of the controller output current to the next
switching frequency below will not be exceeded. If required, select a constant switching
frequency in
.
Display of the current switching frequency
The current switching frequency applied in the controller is displayed in
Operation at an ambient temperature of 45°C
The controller is designed so that operation at an ambient temperature of 45° C without derating is
permissible at a switching frequency of 4 kHz.
