Maximum Demand (%)
The highest value of operation relating to motor limits as de-
fined 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 de-
fined 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 0V to 10V DC). 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 maxi-
mum 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: Mo-
tor Charts.
