The Digistart IS can be commanded to emergency stop the motor, ignoring the soft stop mode set in Pr 2H.
When the circuit across DI4, +24V is opened, the soft starter allows the motor to coast to stop.
To use the emergency stop function, set Pr 3A to 'Emergency Stop' (this is the default setting).
If emergency stop is not required, change the setting of Pr 3A or connect a link across DI4, +24V.
For keypad control, the soft starter requires:
 control supply connections (terminals CSH, CSL, CSR depending on the control voltage)
 programmable input A (DI4, +24V) must be closed or Pr 3A Input A Function must be changed from Emergency Stop
