Diagnose & Remedy
Check main supply voltage (P0210).
Check the following:
1. Ambient temperature must lie within specified
limits
2. Load conditions and duty cycle must be
appropriate
3. Fan must turn when drive is running
Check that duty cycle lies within specified limits
Check that duty cycle and shock loads lie within
specified limits
Check the following:
1. P0611 (motor I
appropriate value
2. P0614 (Motor I
be set to suitable level
