• Fail-safe standstill monitors
  • 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.
  • 3 safety contacts, STOP 0
  • 1 Signalling output
  • Fail-safe delay timer
  • Time adjustable from 0,1 s to 99 min
  • 3 safety contacts
  • 2 Signalling outputs
  • Detects standstill using 2 impulse sensor(s)
  • 2 safety contacts
  • 2 Signalling outputs
  • Detects standstill using 1 or 2 impulse sensors
  • Uses additional standstill signal, e.g. PLC as second input channel
