87 Motor Rated Volts Nameplate Voltage Rating 0 – 600 Volts 230 VAC
88 Motor Base Frequency Nameplate Frequency 25 – 500 Hz 50 or 60 Hz
91 Motor Cosine Phi Nameplate Cosine Phi 0.4 – 0.99 Approx 0.8 2
81 Invoking this parameter begins the auto-calibration routine
NOTES:
1. FLA = Full Load Amps
2. The Cosine Phi is also known as the Power Factor, this will sometimes be on the nameplate as
“PF”. If the Power Factor is given as a %, always use the decimal equivalent (for example a power
factor of 84% would be entered as 0.84) If the Cosine Phi is not provided by the motor manufacturer,
one of the following formulas may be used.

After all of the Parameters have been entered, the drive needs to perform an auto-calibration routine
(Parameter 81). This calibration routine will take several seconds to complete. The user may use the Menu
Key to back up and/or out of the calibration any time prior to the auto calibration. The motor, and therefore
the pump, will not run during this auto-calibration procedure.
