Parameter Write Disable Selection (Pr. 77) - Mitsubishi Electric FR-V560 Instruction Manual

Operation selection function 2 (Pr. 65 to Pr. 79)
(2) Restarting method when stop was made by inputting
1) After the motor has decelerated to
a stop, turn off the STF or STR
signal.
2) Press EXT .
..... (Recovery from
3) Turn on the STF or STR signal.
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 function, 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 even if parameter (all) clear is executed.
• When the motor is stopped from the PU, PS is displayed. An alarm output is not provided.
• Pr. 250 is made invalid.
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.
