AF93/IS903 Parameter Descriptions<br />
USING THE PARAMETERS<br />
Motor Nameplate<br />
Parameters<br />
The values for the following six parameters (HP<br />
Rating, Rated Amps, Rated Efficiency, Rated<br />
Frequency, Rated Speed, and Rated Volts)<br />
should be compared to the motor nameplate after<br />
you install the drive. If the motor nameplate<br />
parameters differ from the information you must<br />
enter the correct setting. These values are<br />
essential for your drive to operate correctly.<br />
Rated Motor Volts<br />
Specifications<br />
Parameter Number: 16<br />
Mnemonic: RATED VOLTS<br />
Value: Volts<br />
Run Locked?: Yes<br />
Factory Setting: Drive Rated<br />
Motor HP Rating<br />
Specifications<br />
Parameter Number: 17<br />
Mnemonic: RATED HP<br />
Value: Hp<br />
Run Locked?: Yes<br />
Factory Setting: Drive Rated<br />
Rated Motor Current<br />
Specifications<br />
Parameter Number: 18<br />
Mnemonic: RATED CURRENT<br />
Value: Amps<br />
Run Locked?: Yes<br />
Factory Setting: Drive Rated<br />
Rated Input Frequency<br />
Specifications<br />
Parameter Number: 19<br />
Mnemonic: RATED FREQUENCY<br />
Range of Adjustment: 30 to 180 Hz<br />
Run Locked?: Yes<br />
Factory Setting: 60 Hz<br />
Rated Nameplate Speed<br />
Specifications<br />
Parameter Number: 20<br />
Mnemonic: RATED SPEED<br />
Range of Adjustment: 500 to 3600 RPM<br />
Run Locked?: Yes<br />
Factory Setting: Motor Dependent<br />
Rated Motor Efficiency<br />
Specifications<br />
Parameter Number: 21<br />
Mnemonic: RATED EFFICIENCY<br />
Range of Adjustment: 50 to 100%<br />
Run Locked?: Yes<br />
Factory Setting: 85%<br />
Load Limit<br />
Specifications<br />
Parameter Number: 22<br />
Mnemonic: LOAD LIMIT<br />
Range of Adjustment: 0 to 200% (2 to 10 Hp) or<br />
0 to 180% (15 to 25 Hp) of<br />
rated load, based on calculated<br />
motor torque rating.<br />
Run Locked?: No<br />
Factory Setting: 150% on constant torque<br />
and 110% on variable<br />
torque rated drives.<br />
This parameter sets the load limit for the drive,<br />
unless it is overridden by ÒANALOG LOAD LIMÓ<br />
(parameter 23). If the drive reaches the Load<br />
Limit (parameter 22) and you are ramping up to<br />
the Maximum Speed (parameter 5), the drive will<br />
go into foldback and stay at the speed where the<br />
load limit was reached. If the load limit control<br />
does not prevent an overload, the drive will shut<br />
down.<br />
