Typical power losses for Motor Modules

The information on the power losses in the previous chapters are maximum values, which
occur in the most unfavorable case. For typical applications, the losses are lower.
The following applies as typical application:
● Maximum motor cable length, 30 m
● 4 kHz pulse frequency
● DC link voltage 540 V - 600 V
The power loss for typical applications can be calculated using the following formula:
P [W] = a + S
