Cause : Under Voltage - Main supply failed. Shock load outside specified limits.
Diagnose & Remedy
Check the following:
1. Supply voltage (P0210) must lie within limits indicated on rating plate
2. Supply must not be susceptible to temporary failures or voltage reductions
3. Enable kinetic buffering (P1240 = 2)
