6.1.4How to recover from PU stop error (PS)

(1)Restarting method when stop was made by pressing

(Method of restarting from indication)

STOP

RESET from operation panel

1)After the motor has decelerated to a stop, turn off the STF or STR signal.

2)Press MODE twice* to display .

CAUTION

When Pr. 79 = 3, press MODE three times to display . Then press to proceed to 3).

(*For monitor screen) ... Refer to page 27 for details of the monitor display provided by pressing MODE .

3)Press SET .

4)Turn on the STF or STR signal.

REMARKS

•When you provide a reset input (RES) during operation, the inverter that is being reset shuts off the output and resets the internal heat integrating value of the electronic thermal relay and the number of retries, and the motor coasts.

•The Pr. 75 value can be set any time. This value does not return to the initial value if parameter (all) clear is executed.

•When the motor is stopped from the PU, and are displayed alternately. An alarm output is not provided.

STOP

Example of stop and restart during external operation

Alternatively, you can make a restart by making a power-on reset or resetting the inverter using the reset terminal of the inverter.

REMARKS

•When you provide a reset input (RES) during operation, the inverter that is being reset shuts off the output and resets the data of the electronic thermal relay, and the motor coasts.

•To make a restart, confirm that the PU is connected and then reset the inverter.

•The Pr. 75 value can be set any time. This value does not return to the initial value if parameter (all) clear is executed.

•When the motor is stopped from the PU, PS is displayed. An alarm output is not provided.

• Since PS is not an inverter error, the inverter can not be reset with	STOP .
	RESET

CAUTION

Do not reset the inverter with the start signal input.

Doing so will start the inverter immediately after it has recovered from the error, causing hazard.
