2.10.3 Maximum output voltage and torque reduction
As the maximum output voltage depends on the pulse frequency to be set, in some cases the torque which is
stated in Planning Guideline 605 2101 must be reduced for values above the rated pulse frequency of 6 kHz.
For F
pulse
> 6 kHz: T
reduction
[%] = 1% * (F
pulse
– 6kHz)
Therefore the maximum torque must be reduced by 1% for each kHz pulse frequency above 6 kHz.
The torque limitation must be taken into account on reaching the break frequency. The same applies for the
degree of modulation (P218). With the factory setting of 100%, in the field reduction range a torque
reduction of 5% must be taken into account:
For P218 > 100%: T
reduction
[%] = 1% * (105 – P218)
Above a value of 105%, no reduction needs to be taken into account. However, with values above 105% no
increase in torque above that of the Planning Guideline will be achieved. Under certain circumstances,
degrees of modulation > 100% may lead to oscillations and motor vibration due to increased harmonics.
ATTENTION
At pulse frequencies above 6 kHz (400/480V devices) or 8 kHz (230V) devices, the
reduction in power must be taken into account for the design of the drive unit.
If parameter (P218) is set to < 105%, the derating of the degree of modulation
must be taken into account in the field reduction range.
