Example Settings

Parameter
Phase Reversal
This parameter allows the user to enable phase reversal
protection.
Starts Per Hour
Allows the user to limit the number of starts during a one
hour period.
Restart Attempts ①
Determines the number of attempts the controller will
make to automatically restart the motor after a fault.
①
Restart Delay
Provides a delay period prior to a restart attempt.
ETM Reset
Allows the user to reset the accumulated value of the
elapsed time meter.
②
Parameter Management
The newly programmed parameter values can be saved
to memory, or the factory defaults parameter values can
be recalled.
①
The Auto Restart feature is not available.
②
The new programmed parameter values will not be stored to the EEPROM without the user's
direction in parameter management: Store In EE
