47 motor ol hertz, 48 motor overload amps, 49 imbalance limit – Rockwell Automation Liqui-Flo 1.5 General Purpose and Vector Duty User Manual
Page 43: 50 imbalance time
Parameter Descriptions
4-11
Selects the output frequency below which the motor operating current is derated. The
motor thermal overload will generate a fault at lower levels of current. For all settings
of overload Hz other than zero, the overload capacity is reduced to 70% when output
frequency is zero.
Sets the amps threshold for motor overload fault.
Motor FLA x OL Factor = Operating Level
Sets the fault threshold for motor current imbalance.
Sets the time delay in generating a motor current imbalance fault.
