What Er-H means
LSI error detection (Power PCB) p. 208
Common causes
- When an error occurred in the LSI on the power printed circuit board, this function stops the inverter. (Applicable to: 200 V series 45 kW or above, and 400 V series 55 kW or above) p. 208
- When the inverter has stopped because of a trip, this function allows the inverter to automatically reset itself and restart. (You can specify the number of retries and the latency between stop and reset.) p. 208
- Protects the inverter against surge voltages which might appear between one of the power lines for the main circuit and the ground. p. 208
- Upon detecting a loss of a frequency command (because of a broken wire, etc.), this function issues an alarm and continues the inverter operation at the preset reference frequency (specified as a ratio to the frequency just before the detection). p. 208
- Upon detecting an instantaneous power failure lasting more than 15 msec, this function stops the inverter output. p. 208
- In the event of overheating of the heat sink or an overload condition (alarm code: H70 / H71), the output frequency of the inverter is reduced to keep the inverter from tripping. p. 208
