Name
PTC - A PTC thermistor input stops the inverter output for motor
thermistor protection.
A PTC thermistor is connected between terminals [C1] and
[11], and a 1-kΩ=external resistor is connected between
terminals [13] and [C1].
Overload Outputs a preliminary alarm at a preset level before the motor is
early stopped by the electronic thermal function for the purpose of
warning protecting the motor.
Stall prevention Operates when instantaneous overcurrent limiting is active.
- 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).
External alarm - Stops the inverter output with an alarm through the digital input
input signal (THR).
Alarm relay - The inverter outputs a relay contact signal when the inverter
output issues an alarm and stops the inverter output.
(for any fault)
< Alarm Reset >
The alarm stop state is reset by pressing the
digital input signal (RST).
< Saving the alarm history and detailed data >
The information on the previous 4 alarms can be saved and
displayed.
Memory error The inverter checks memory data after power-on and when the
data is written. If a memory error is detected, the inverter stops.
Remote keypad The inverter stops by detecting a communication error between
communications the inverter and the remote keypad (option) during operation from
error the remote keypad.
CPU error If the inverter detects a CPU error caused by noise or some other
factor, the inverter stops.

Description
Pressing key on the keypad forces the inverter to
decelerate and stop the motor even if the inverter is
running by any run commands given via the terminals
or communications (link operation). After the motor
stops, the inverter issues alarm "E 6."
