1 System fan, 701 alarm, 8901#0 parameter is changed to 1 to temporarily shield the alarm (OIC system);
2. If the driver alarms, please replace or clean the fan, and be careful not to lose the origin of the machine tool. The servo drive has 2 fans, make no mistake. 3 wires 24V, red (24V) black (0V) white or yellow (detection) cannot be shielded by parameters. You can connect the detection line to 0V for shielding (for OIB, OIC, OID systems, OIF and 31ib cannot).
3. The spindle motor fan is a 3-phase 220V AC fan. If it fails, there will be no alarm. However, if the spindle runs at high speed for a long time, the spindle motor overheating alarm may easily occur.
