3.4 Over current and stalled rotor protection
This protection scheme addresses the starting inrush current and stalled-rotor current.
The over current and stalled rotor current threshold is set in WinESG parameterization/device settings panel shown in
the illustration below or Modbus function code 06 register 18. The over current is settable from 100 to 800% of motor
current (Ir)
If a current exceed
s
this current threshold for a pre-defined timer set in WinESG parameterization/timer panel shown in
the illustration below or Modbus function code 06 register 32 a failure or warning will be generated depending o
n
the
alarm setting. The over current time is settable from 0.1 to 6553.5 seconds.
