Motor control (MCTRL)
Parameterisable additional functions
Limiting the maximum output frequency
The maximum output frequency (C00910
) 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 C00144
.
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 C00018
.
Display of the current switching frequency
The current switching frequency applied in the controller is displayed in C00725
.
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.
