Stop/restart example for external operation
•• The motor can be restarted by making a reset using a power supply reset or RES signal.
CAUTION
Even if Pr. 250 Stop selection is set to other than "9999" to select coasting to a stop, the motor will not coast to a stop but
decelerate to a stop by the PU stop function during external operation.
Do not reset the inverter with the start signal on. Doing so will cause the inverter to start immediately after a
reset, leading to hazardous conditions.
(5) Reset limit
•• Setting can be made for the 01800 or more.
•• You can set Pr. 75 to disable reset operation until the thermal cumulative amount reaches 0 when a thermal trip
(THM, THT) or an overcurrent trip (OC1 to OC3) occurs consecutively twice.
•• When Pr. 75 = "100 to 103, 114 to 117", reset limit is made valid.
REMARKS
When the power-on reset (no control power is supplied) is made, the thermal cumulative amount is cleared.
