This is the first page of Setpoints. The MESSAGE RIGHT, MESSAGE LEFT, MESSAGE UP and
MESSAGE DOWN keys may be used to view all of the setpoints data.
The Setpoint values themselves are changed by pressing the VALUE UP or VALUE DOWN keys
until the desired value is reached. When a Setpoint is adjusted to its proper value the STORE key

will be permanently saved.

Setpoints may be changed while the motor is running; however it is not recom-
mended to change important protection parameters without first stopping the motor.
WARNING
Setpoints will remain stored indefinitely in the MM2 internal non-volatile memory even when control
power to the unit is removed. Protection parameters are based on the entered data. This data must
be complete and accurate for the given system for reliable protection and operation of the motor.
All Setpoint messages shown contain the factory default settings.
