Current detection function parameters

2.5 Current detection function parameters

2.5.1 Output current detection functions
(Pr. 48
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 or contact output
terminal.

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