Operation
CAUTION
We recommend testing the soft starter's setup on a low voltage motor before beginning operation on a medium
voltage motor. This allows the operator to test that the soft starter is correctly connected to the auxiliary equipment.
Start, Stop and Reset Commands
The soft starter can be controlled in three ways:
•
using the buttons on the controller
•
via remote inputs
•
via a serial communication link
The LCL/RMT button controls whether the MVE will respond to local control (via the controller) or remote control (via the remote
inputs).
The Local LED on the controller is on when the soft starter is in local control mode and off when the soft starter is in remote
control mode.
Control via the fieldbus communication network is always enabled in local control mode, and can be enabled or disabled in remote
control mode (parameter 6R
Comms in Remote
). Control via the serial communication network requires an optional
communication module.
The STOP button on the controller is always enabled.
Using the Soft Starter to Control a Motor
To soft start the motor, press the START button on the controller or activate the Start remote input. The motor will start using the
start mode selected in parameter 2A.
To stop the motor, press the STOP button on the controller or activate the Stop remote input. The motor will stop using the stop
mode selected in parameter 2H.
To reset a trip on the soft starter, press the RESET button on the controller or activate the Reset remote input.
To stop the motor with a coast to stop, regardless of the setting of parameter 2H
Stop Mode
, press the local STOP and RESET
buttons at the same time. The soft starter will remove power from the motor and open the main contactor, and the motor will
coast to stop.
