Inverter Load; Motor Command Speed; Actual Motor Speed; Actual Elevator Speed - KEB COMBIVERT F5 Instruction Manual

Inverter load
Motor command speed
Actual motor speed
Actual elevator speed
Diagnostic Parameters
Display of the actual inverter load in %. 100% equals rated load of
the inverter.
Displays the motor set speed in rpm, calculated from the system
data.
Displays the actual motor speed in rpm measured from the motor
encoder .
Actual motor speed should always be the same sign (polarity) as
LF.88 and within 20 rpm. Otherwise there is a problem with the
encoder, the encoder cable, or the setting of parameters LF.28.
i
To verify the encoder operation with induction motors, run
the elevator drive in open loop (LF.30=0), set the inspection
speed (LF43) to 50% of contract speed and run the car empty
up. The actual motor rpm value displayed in LF.89 should be
nearly equal to the value displayed in LF.88. If the value in LF.89
varies by more than +/- 10 rpm or the value is greater or less
than LF.88 by more than 20 rpm, there is a problem with either
the encoder or the encoder cable.
Display of the car speed in ft/min; only when the encoder is
connected.
This is a calculated value. The car speed should always be verified
with an independent measuring device.
