.5.1 Output current detection functions
If the output remains higher than the
Pr. 48 setting during inverter operation
for longer than the time set in Pr. 49,
the output current detection signal
(Y12) is output from the inverter's
open collector output terminal.

Description
48
Set the output current detection level.
100% is the rated inverter current.
49
Set the output current detection time. Set the time from when the output
current has risen above the Pr. 48 setting until the output current detection
signal (Y12) is output.
CAUTION
•
Once turned on because the current has risen above the preset detection level,
the output current detection signal is held on for at least 100ms (approximately).
•
Using Pr. 64 or Pr. 65 to change terminal assignment may affect the other
functions. Make setting after confirming the function of each terminal.
