Series: SV670N-LK, SV670N-PTC, SV670NS-INT
Freewheeling diode junction temperature too high
servo drive
Meaning: The estimated temperature of the servo drive freewheeling diode is too high and has reached the fault threshold H0A.18.
Possible causes
- 1. ambient temperature too high 2. repeatedly resetting the overload fault by switching off the power supply after an overload
- 3. fan failure
- 4. inappropriate servo drive mounting orientation or spacing between servo drives
- 5. servo drive fault
