Useful functions Parameter
6 - 278
The pulse output of the current average value monitor signal (Y93) is shown below.
For the terminal used for the Y93 signal output, assign the function by setting "93" (positive logic)
or "193" (negative logic) to Pr. 190 or Pr. 197. The function can not be assigned to Pr. 192 "ABC
terminal function selection".
The output current is unstable (transient state) right after the operation is changed from the ac-
celeration/deceleration state to the constant speed operation. Set the time for not obtaining
(mask) transient state data in Pr. 556.

Data output mask time
When the speed has changed to constant from
acceleration/deceleration, Y93 signal is not output
for Pr. 556 time.
Start pulse
Output as Hi pulse shape for 1s (fixed)
Time and output current set in Pr. 555 are averaged
Output current average value pulse
The averaged current value is output as low pulse shape for 0.5
to 9s (10 to 180%) during start bit output.
