0 100 RUN Inverter running
Output when the start command is input.
For V/F control, this signal is output during operation when the inverter output
speed rises to or above the starting speed.
During DC injection brake, 0 speed control or servo lock, this signal is not output.
1 101 SU Up to speed Refer to Pr. 41 "up-to-speed sensitivity" (page 95).
2102IPF
Instantaneous
power failure or
undervoltage
Output at occurrence of an instantaneous power failure or undervoltage.
3 103 OL Overload alarm
Output when torque or speed limit is activated.
For V/F control, this signal is output while the stall prevention function is activated.
4104FU

Third output speed
detection
Refer to Pr. 116 "third speed detection" (page 95).
7107RBP
Regenerative brake
prealarm
Output when 85% of the regenerative brake duty set in Pr. 70 is reached.
8108THP
Electronic thermal
relay function
prealarm
Output when the electronic thermal relay function cumulative value reaches 85% of
the preset level.
10 110 PU PU operation mode Output when the PU operation mode is selected.
11 111 RY
Inverter operation
ready
Output when the inverter can be started by switching the start signal on or while it
is running.
