6.1.4 How to recover from PU stop error (PS)
(1) Restarting method when stop was made by pressing from operation panel
(Method of restarting from indication)
1) After the motor has decelerated to a stop, turn off the STF or STR signal.
2) Press twice* to display .
(*For monitor screen) ... Refer to page 27 for details of the monitor display provided by pressing .
3) Press .
4) Turn on the STF or STR signal.
(2) Restarting method when stop was made by pressing from PU
Alternatively, you can make a restart by making a power-on reset or resetting the inverter using the reset terminal of
the inverter.
CAUTION
When Pr. 79 = 3, press three times to display . Then press to proceed to 3).
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.
1) After the motor has decelerated
to a stop, turn off the STF or
STR signal.
2) Press .

3) 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
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 .
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.
