Current characteristics
The maximum output current of the EVS9326 ... EVS9332 devices is limited
under certain operating conditions:
ƒ At output frequencies f
out
< |5 Hz| and heatsink temperatures
J
K
> 40° C.
ƒ The current limitation depends on the switching frequency.

Current derating characteristics
0 Operation at switching frequency f
chop
= 8 kHz (C0018 = 1)
The current limitation follows the characteristic curve
At output frequencies f
out
< |5 Hz| and heatsink temperatures
J
K
= 40 ... 80 °C, the current limit is steplessly adjusted in the
range
1 Operation at switching frequency f
chop
= 16 kHz (C0018 = 2)
The current limitation follows the characteristic curve and is independent of
the heatsink temperature
At automatic change−over of the switching frequency (C0018 = 0), the controller
operates at f
chop
= 16 kHz. The current limitation follows the characteristic
curve
1.
If an increased torque is required (e.g. acceleration processes), the controller
automatically switches over to f
chop
= 8 kHz. The current limitation follows the
characteristic curve
0.
