P7-12 Premagnetization time

Setting range: 0 – 5000 ms

Use this parameter to define a premagnetization time. Consequently, there is a corresponding start delay when the inverter is enabled. If the value is too small, the inverter might generate an overcurrent fault (O-I or hO-I) if the acceleration ramp is too short.

In the case of operating modes for synchronous motors, this parameter, together with P7-14, is used for the initial rotor adjustment. In particular, it must be adjusted for high moments of mass inertia.
