    2. TROUBLE SHOOTING 2.1 Inverter trip contents, remedy, advice Trip It’s one of INV failure by locked motor, fast ACC/DEC because big current will be flown. By over current detection, INV will shut the output by the hardware. This detection will be done by AC Over current detection at Over current will be detected about output stage...
  • Page 20 Trip If Instant power failure 15ms or more happened, INV will shut the output. If the instant power failure is longer Instant power failure than preset allowable time or affordable control supply voltage time, INV will work as normal power off. This detection means INV will re-start with the run command after the long instant power failure.
