PNP connection through the P1 connector (figure 2). It is recommend to add an EMI line filter between the power
supply and the drive to increase noise immunity for the drive in interference environments.

4.2 Fault Output Connection
When over voltage or over current protection happens, EM882S red status LED light will blink and the impedance
state between ALM+ and ALM- will change (from low to high or high to low depending on configuration) and can thus
be detected. Fault output connection is optional, and it can be connected either in sinking or sourcing.
