4.22.4 Current average value monitor signal (Pr. 555 to Pr. 557)
The pulse output of the current average value monitor signal (Y93) is shown above.
For the terminal used for the Y93 signal output, assign the function by setting "93" (positive logic) or "193" (negative logic)
to
Pr. 190 and Pr. 191 (output terminal function selection)
. The function can not be assigned to
Pr. 192 A,B,C terminal function
selection
.
1) Setting of
Pr.556 Data output mask time
The output current is unstable (transient state) right after the operation is changed from the acceleration/deceleration state
to the constant speed operation. Set the time for not obtaining (mask) transient state data in
Pr. 556
.
The average value of the output current during
constant speed operation and the maintenance timer
value are output as a pulse to the current average
value monitor signal (Y93).
The pulse width output to the I/O module of the
programmable controller or the like can be used as a
guideline due to abrasion of machines and elongation
of belt and for aged deterioration of 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.

Output current average value (A)
1) Data output mask time
When the speed has changed to
constant from acceleration/deceleration,
Y93 signal is not output for
Pr. 556
time.
2) Start pulse
Output as Hi pulse shape for 1s (fixed)
Output current set in
Pr. 555

3) Output current average value pulse
The averaged current value is output for 0.5 to 9s
(10 to 180%) during start bit output.
Signal output time =
Pr. 557

4) Maintenance timer pulse
The maintenance timer value (
Pr. 503
) is
output as Hi pulse shape for 2 to 9s
(16000h to 72000h)
Signal output time =
40000h
5) End pulse
Output as low pulse
