Possible Cause
• Cold weather mode is not enabled, and
unit temperature is less than -10 degree.
• Cold weather mode is enabled and Under
Temp Fault Override is not set, unit
temperature is less than -30 degree.
• Cold weather mode is enabled and Under
Temp Fault Override is not set, unit
temperature is -20~ -30 degree. The temp
<-20 degree when cold weather start
times out.
External supply on the DeviceNet
communication connector is not present.
Digital input is activated for external
fault input.
Digital input is activated for external
fault input.
Drive degree greater than
(DCI_wDriveOverTempThreshold value -10
degree) and less than
DCI_wDriveOverTempThreshold value,report
drive over temperature warning.

Remedy
If unit temp -20 ~ -10 degree, start motor in
cold weather mode.
If unit temp <-20°, warm up unit above
-20°C for proper operation using cold
weather mode.If still < -20° when cold
weather mode times out, try higher output
voltage in cold weather mode.
Check voltage and wiring of power supply
of the DeviceNet communication.
Check digital input settings and verify input
level, could be an external device causing
fault.
