Cause : Thermal trip comes when the heatsink temperature reaches the overheat fault level. The drive will display "E21" and stop operation due to temperature of the heatsink has exceeded the overheat detection level..

  1. Ambient temperature too high.
  2. Fan is damaged.
  3. Lower the ambient temperature.
  4. Fan air duct is blocked- clear the air duct.
