UNDERSTANDING SETPOINTS
CAUTION:

Setting text abbreviations

5–2
The pages containing setpoint fields, except for the inputs and outputs pages, are in a
common format. This is a simple tabular format with two columns: setpoint name and
units, and setpoint value. Setpoints for features that are not enabled are omitted from the
page.
Setpoints may be changed while the motor is running; however it is not recommended
to change important protection parameters without first stopping the motor.
Setpoints will remain stored indefinitely in the 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.
The following abbreviations are used in the setpoints pages.
• A, Amps: amperes
• AUX: auxiliary
• CBCT: core balance current transformer
• COM, Comms: communications
• CT: current transformer
• FLA: full load amps
• FV: full voltage
• G/F: ground fault
• GND: ground
• Hz: Hertz
• kohms: kilo-ohms
• MAX: maximum
• MIN: minimum
• SEC, s: seconds
• UV & U/V: undervoltage
• VT: voltage transformer
• %MNV: percent of motor voltage
• %UB: percent unbalance
• %NCV: percent of nominal control voltage
• %MNR: percent of motor nominal rating
• Ctrl: control
• Hr & hr: hour
• O/L: overload
• UTC: co-ordinated universal time
• ops: operations
• mcc: motor control center
