OVER TEMPERATURE FAULT

Was bedeutet 908 ?

The calculated SCR junction temperature, derived from thermistor heat sink measurements and the heating effects of the measured armature output current, has exceeded 125 degrees Centigrade. This fault will not shut down the drive.

• Ambient temperature surrounding the drive cabinet is excessively high.
• The air filter within the cabinet is clogged, restricting airflow.
• The heatsink fins are clogged with dust or debris, impairing heat dissipation.
• Failure of one or more cooling fan(s) in the power cube.
