Description The Stop Mode parameter allows for the most suitable stop of the motor based on the application.
Options LED LCD
CoS Coast Coast: A coast to stop should be used when no special stopping
requirements are necessary; Example: crushers, balls mills,
centrifuges, belts, conveyor. In Low Voltage systems, the bypass
contactor is opened before the SCRs stop gating to reduce wear on the
contactor contacts. (Default)
SdcL Voltage Decel Voltage Decel: In this mode, the starter linearly phases-back the SCRs
based on the parameters Decel Begin Level, Decel End Level, and
Decel Time.
tdcL TT Decel TruTorque Decel: In this mode, the starter linearly reduces the motor
torque based on the Decel End Level and Decel Time.
Note: The MX stops the motor when any fault occurs. Depending on the application, it may be
desirable for the motor to be stopped in a controlled manner (Voltage Decel or TT Decel) instead of
being allowed to coast to a stop when this occurs. This may be achieved by setting the Controlled
Fault Stop Enable parameter to On. Be aware however that not all fault conditions allow for a
controlled fault stop.
