(1) Output current detection (Y12 signal, Pr. 150, Pr.
151, Pr. 166, Pr. 167)
⋅ The output power detection function can be used for
excessive torque detection, etc.
⋅ If the output current remains higher than the Pr. 150 setting
during inverter operation for longer than the time set in Pr. 151,
the output current detection signal (Y12) is output from the
inverter's open collector or relay output terminal.
⋅ When the Y12 signal turns on, the ON state is held for the
time set in Pr. 166 .
⋅ When Pr. 166 = "9999", the ON state is held until a next start.
⋅ At the Pr. 167 setting of "1", the inverter output is stopped and
the output current detection alarm (E.CDO) is displayed when
the Y12 signal turns on. When an alarm stop occurs, the Y12
signal is on for the time set in Pr. 166 at the Pr. 166 setting of
other than 9999, and remains on until a reset is made at the
Pr. 166 setting of 9999.
⋅ Set "12 (positive logic)" or "112 (negative logic)" to any of Pr.
190 to Pr. 196 (output terminal function selection) to assign the
function of the Y12 signal to the output terminal.
Description
Set the output current detection level.
100% is the rated inverter current.
Set the output current detection period.
Set the time from when the output current
has risen above the setting until the output
current detection signal (Y12) is output.
Set the zero current detection level. The
rated inverter current is assumed to be
100%.
Set this parameter to define the period
from when the output current drops below
the Pr. 152 value until the zero current
detection signal (Y13) is output.
Set the retention time when the Y12 signal
is on.
The Y12 signal on status is retained. The
signal is turned off at the next start.
Operation continues when the Y12 signal
is on
The inverter is brought to an alarm stop
when the Y12 signal is on. (E.CDO)
