Description
The servo drive has a serious alarm and cannot work normally. It needs to be

The servo drive warns that the device will not be damaged for the time being,
but if it is not handled correctly in time, it may cause a high level fault
output.
DO terminal outputs WARN signal.
6.1 Fault diagnosis and treatment
Faults can be divided into:
●Non-resettable NO.1 failure;
● Resettable NO.1 fault;
● Resettable NO.2 fault.
Among them, resettable indicates that after fault handled, we can clear the servo fault status by set P11-
01 to 1 or configure DI function FunIN.2: ALM-RST alarm resets.
Non-resettable means that after the fault is handled, drive needs to be re-powered
.
The NO.1 and NO.2 faults have different stop modes. The NO.1 fault is free to stop and keeps running
freely. The NO.2 fault stop mode is set by P00-12.
NO.1, NO.2 reset method for resetable fault: first turn off the servo enable signal (S-ON is set to OFF),
then set P11-01=1 or use DI function 2.
When the servo drive fails, the fault "Er.xxx" appears on LED display.
