Feeder motor stops and red LED on inverter U1 is on

Possible cause:

• U1 inverter feeder motor reach the adjusted current limit because sheet stack falls down/feeder crash. Remove sheet stack and check the mechanical adjustment of blank magazine and feeder.
• U1 inverter current limit is set too low. Can be adjusted with parameter C022. Attention! Before you increase that limit check if the feeder can be turned by hand easily and mechanical condition is perfect.
• For reset inverter switch off and on the machine.
