Motor Protection While the Basic Set Up group allows the user to get started with a minimum
number of parameters to modify, the Motor Protection group allows full access
to the SMC Flex controller's powerful parameter set. Following is a listing of the
additional setup parameters provided.
Note: The majority of parameters have a Fault and an Alarm setting.

Parameter Mgmt Recall of factory default parameter values. Ready, Load Default
(1) Starting Mode must be programmed to Soft Start to obtain access to the Initial Torque parameter.
(2) Starting Mode must be programmed to Current Limit to obtain access to the Current Limit Level parameter.
(3) Refer to the I/O section on page 36 and Notes on page 38 for MV specific functionality.
(4) This is not to indicate how the motor windings are configured. Do not select "Delta" for MV applications.
(5) When programmed for 'Emergency Run' and the Option 2 input is energized, a 'Start' command will first close the bypass contactor, then the line contactor for an across-the-line start of the motor. A
'Stop' command will open the line contactor first and allow the motor to coast, regardless of the programmed 'Stop Mode'. For Pump Option modules, the Option 2 input defaults to 'Emergency Run' for
MV applications.
