7.1.8 Fault output
When the drive fails, the drive will have a fault alarm output and the servo system will change from
the enabled state to the disable state.
To use this function, a digital output of the servo drive is congured as ALM function.
Parameters P5-12 ~ P5-13 set the function of the digital output Y1 ~ Y2 of the drive. Should either
of these inputs be assigned as the fault output.
Type Signal Symbol Setup Value Signal logic Function
Output ALM
1
Closed When the output is CLOSED, it means that the drive has a fault
Open
When the output is OPEN, it means the drive is in normal state and no
fault is occurred.
2
Open When the output is OPEN, it means that the drive has a fault.
Closed
When the output is CLOSED, it means the drive is in normal
state and no fault are occurred.
