Alarm
output
[30A/B/C]
Blown fuse Upon detection of a fuse blown in the inverter’s main circuit, this function stops
the inverter output. (Applicable to 125HP or above (for both 3-phase 208 V and 3-
phase 460 V))
Ffus Yes
Abnormal
condition in
charger circuit Upon detection of an abnormal condition in the charger circuit inside the inverter,
this function stops the inverter output. (Applicable to 50HP or above (3-phase 208
V) or 75HP or above (3-phase 460 V))
pbf
Yes
In the following cases, the inverter stops running the motor to protect the motor in
accordance with the electronic thermal overload protection setting. Electronic
thermal
overload
- Protects general-purpose motors over the entire frequency range (F10 = 1.)
- Protects inverter motors over the entire frequency range (F10 = 2.)
* The operation level and thermal time constant can be set by F11 and F12.
0l1 Yes
A PTC thermistor input stops the inverter output for motor protection. PTC
thermistor
Connect a PTC thermistor between terminals [V2] and [11] and set the function
codes and slide switch on the control PCB accordingly.
0h4 Yes
Motor protection
Overload
early
warning Outputs a preliminary alarm at a preset level before the motor is stopped by the
electronic thermal overload protection for the motor.

Operates when instantaneous overcurrent limiting is active. Stall
prevention
- Instantaneous overcurrent limiting:
Operates if the inverter's output current exceeds the instantaneous overcurrent
limit level, avoiding tripping of the inverter (during constant speed operation or
during acceleration).
—
—
Alarm relay
output
(for any fault) - The inverter outputs a relay contact signal when the inverter issues an alarm
and stops the inverter output.
< Alarm reset >
The alarm stop state is reset by pressing the
key or by the digital input
signal (RST).
< Saving the alarm history and detailed data >
The information on the previous 4 alarms can be saved and displayed.

Yes
Memory error
detection
The inverter checks memory data after power-on and when the data is written. If
a memory error is detected, the inverter stops.
er1
Yes
Keypad
communi-
cations error
detection The inverter stops by detecting a communications error between the inverter and
the keypad during operation using the keypad.
er2
Yes
CPU error
detection If the inverter detects a CPU error or LSI error caused by noise or some other
factors, this function stops the inverter
er3
Yes
Option
communi-
cations error
detection Upon detection of an error in the communication between the inverter and an
optional card, stops the inverter output.
er4 —
Option error
detection When an option card has detected an error, this function stops the inverter output.
er5
—
Operation
error detection STOP
key
priority
Pressing the key on the keypad forces the inverter to decelerate
and stop the motor even if the inverter is running by any run
command given via the terminals or communications link. After the
motor stops, the inverter issues alarm
