PARAMETERS
4.2.51 Current average value monitor signal (Pr. 555 to Pr. 557)
(no function for the 400V class)
Pr. 555 "current average time"
Pr. 556 "data output mask time"
Pr. 557 "current average value monitor
signal output reference current"
The average value of the output current during constant speed operation and the
capacitor life timer value (Pr. 503) are output as pulses to the current average value
monitor signal (Y93).
The pulse width measured by inputting the signal to the I/O module of the PLC or the
like can be used as a guideline for increase in output current due to abrasion of
peripheral machines and elongation of belt and for aged deterioration of peripheral
devices to know the maintenance time.
The current average value monitor signal (Y93) is output as pulse for 20s as 1 cycle and
repeatedly output during constant speed operation.
