Useful functions
The pulse output of the current average value monitor signal (Y93) is shown below.
Fig. 6-220: Output of the pulse signal Y93
For the terminal used for the Y93 signal output, assign the function by setting "93" (source logic)
or "193" (sink logic) to any of Pr. 190 to Pr. 194 "Output terminal function selection". (The func-
tion can not be assigned to Pr. 195 "ABC1 terminal function selection" and Pr. 196 "ABC2 ter-
minal function selection".)
Setting of Pr. 556 "Data output mask time"
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.

Y93
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

Maintenance timer pulse
The maintenance timer value (Pr.503) is output as Hi
output pulse shape for 2 to 9s (16000h to 72000h).
