CORRECTIVE ACTION
• Check the input data.
• Check the drive and motor capacities.
• Check the input data.
• Check the motor wiring.
• Increase acceleration time ( C1-01 ).
• Increase torque limit values ( L7-01 , -02 ) if they
are reduced from factory settings.
• Uncouple the motor from the load.
• Swap two motor leads.
OR
• Swap channels on the input to the PG-X2 card
(on terminal block TA1, swap wires at terminals
4 & 6 and swap wires at terminals 5 & 7).
• Uncouple motor from load.
• Increase acceleration time ( C1-01 ).
• Check input data, especially the encoder PPR
( F1-01 ).
• Check Table 6-1 for specific minor
fault indicated by "XXX."
• Pulse generator is disconnected from
the PG-X2 card (Terminal TA1).
Check PG wiring.
