Stop/restart example for external operation
• The motor can be restarted by making a reset using a power supply reset or RES signal.
CAUTION
⋅ If Pr. 250 Stop selection is set to other than "9999" to select coasting to a stop, the motor will not be coasted to a stop but
decelerated 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.
