Sensor-free detection of standstill by monitoring e.m.f.
Direct connection to three-phase motors
Suitable for connection to a frequency converter with the following interface date: rotary hysteresis 0 … 1000 Hz; switching frequency of the end level up to 16 kHz; engine voltage range 0 … 400 V
This fail-safe standstill monitor has the particular advantage that no adjustment for a required-value is needed during comissioning.
