1.8.5 Output shut-off (MRS signal): Setting "6"

Short the output stop terminal MRS-SD during inverter output to cause the inverter to immediately stop the output. Open terminals MRS-SD to resume operation in about 10ms. Terminal MRS may be used as described below:

(1) To stop the motor by	frequency	Motor coasted
Terminals MRS-SD must be shorted	frequency	to stop

(2) To provide interlock to disable			frequency"

After MRS-SD have been shorted, the	MRS -SD
inverter cannot be operated if the start	Across	ON
signal is given to the inverter.	STF-SD

	(STR)

(3) To coast the motor to stop

The motor is decelerated according to the preset deceleration time and is stopped by operating the DC injection brake at 3Hz or less. By using terminal MRS, the motor is coasted to a stop.

1.8.6 External thermal relay input: Setting "7"

When the external thermal relay or thermal relay built in the motor is actuated, the inverter output is shut off and an alarm signal is given to keep the motor stopped to protect the motor from overheat. If the thermal relay contact is reset, the motor is not restarted unless the reset terminal RES-SD is shorted for more than 0.1s and then opened or power-on reset is performed.

The function may therefore be used as an external emergency stop signal input.
