If Maximum Speed Error Threshold (H15) = 0 then Trip 62 (Speed err) is disabled.
Maximum Speed Error (J57) shows the maximum speed error for the current travel. It is reset when a new travel begins.
This indicates the number of travels started for the system. It includes all complete and aborted travels i.e. every time Elevator Software State (J03) is
>1 the travel count increments.
The Output Power (J59) is the power flowing via the a.c. terminals of the drive. The power is derived as the dot product of the output voltage and
current vectors, and so this is correct even if the motor parameters are incorrect and the motor model does not align the reference frame with the flux
axis of a motor in RFC-A mode. For Open-loop, RFC-A and RFC-S modes a positive value of power indicates power flowing from the drive to motor.
For Regen mode a positive value of power indicates power flowing from the supply to the regen drive.
The output frequency is not controlled directly, but the Output Frequency (J60) is a measurement of the frequency applied to the motor.
The Output Voltage (J61) is the rms line to line voltage at the AC terminals of the drive.
This indicates the maximum power sampled in the previous travel. The value is taken from Output Power (J59) and is filtered using a first order 50 ms
time constant filter. This value is reset at the beginning of a new travel.
