PerfectSpeed ® NEMA 48 Pump Motor
Max T orque
The torque point at the highest speed just below power limiting of the motor.
Maximum Demand (%)
The highest value of operation relating to motor limits as defined in the Motor Mode of
Operation. It is represented as the upper limit of the Y-axis in the Motor Profile graph.
Maximum Input (%)
The highest value of control method (on-board potentiometer, or 0 – 10 VDC). It is
represented as the upper limit of the X-axis in the Motor Profile graph.
Minimum Demand (%)
The lowest value of operation relating to motor limits as defined in the Motor Mode of
Operation. It is represented as the lower limit of the Y-axis in the Motor Profile graph.
Minimum Input (%)
The lowest value of control method (on-board potentiometer, or 0 – 10 VDC). It is
represented as the lower limit of the X-axis in the Motor Profile graph.
Message Timeout
A message referring to a communication failure between the computer and motor.
Motor HP
The horsepower rating of the motor
.
Motor flow Limit
A user-defined limit (in GPM) equating to 100% demand in flow Mode of Operation.
Motor Ramp Rate
The time (in seconds) it takes the motor to go from 0 to maximum RPM as defined by
the maximum operating parameters. Also called motor slew rate.
Motor Speed Limit
A user-defined limit (in RPM) equating to 100% demand in Speed Mode of Operation.
Motor Power Limit
A user-defined limit (in Watts) of output power. The parameter cannot be less than
25% of the value in the Motor Table. Refer to Appendix A: Motor Charts.
Motor Torque Limit
A user-defined limit (in lb – in) equating to 100% demand in Torque Mode of
Operation. The parameter cannot be less than 25% of the value in the Motor Table.
Refer to Appendix A: Motor Charts .
