PNO Parameter Descriptions
Duty Selection
Heavy Duty
( typically 150%, 60s).
Normal Duty
allowing higher continuous ratings with less overload capability ( typically 110%, 60s).
% are related to the Drive/stack ratings.
For example, a 12A drive ( @4kHz ) under Normal Duty becomes a 10A drive ( @4kHz) under Heavy Duty
DC Link Voltage
This shows the voltage across the dc link capacitors.
Actual Speed RPM
This parameter changes according to the
Control Strategy:
In Vector Control mode the parameter shows the calculated mechanical speed of the motor shaft in rpm.
In Volts-Hertz Control mode the parameter shows motor synchronous speed in rpm.
Actual Speed rps
This parameter changes according to the
Control Strategy
:
In Vector Control mode the parameter shows the calculated mechanical speed of the motor shaft in revolutions per second.
In Volts-Hertz Control mode, the parameter shows the motor synchronous speed in revolutions per second.
Actual Speed Percent
This parameter changes according to the
Control Strategy
•
In Vector Control mode the parameter shows the calculated mechanical speed of the motor shaft as a percentage of the user
maximum speed setting (
100% Speed in RPM
in the
Scale Setpoint
function).
•
In Volts-Hertz Control mode, the parameter shows the electrical drive output frequency as a percentage of the user
maximum speed setting (
100% Speed in RPM
in the
Scale Setpoint
function).
DC Link Volt Filtered
This shows the filtered voltage across the dc link capacitors.
