Name
Electronic Stops the inverter output in accordance with the setting of the
thermal electronic thermal overload relay to protect the motor.
overload
This function protects general-purpose motors and inverter motors
relay
over the entire frequency range, as well as protecting the 2nd
motor.
* The operation level and thermal time constant (0.5 to 75.0
minutes) can be set.
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 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 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 issues an
alarm and stops the inverter output.

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.
CPU error If the inverter detects a CPU error caused by noise or some other
factor, the inverter stops.

Description
Pressing the 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 Er6.
Inverters prohibit any run operations and displays Er6
on the LED monitor if a run command is present at the
time of any of the following status changes.
- Powering up
- An alarm ( key turned ON) is released or an
alarm reset (RST) is input.
- Link command (LE) has switched inverter operation and
the run command in the source to be switched is active.
