3.2 P2 - Fault and Brake Output Connector

Pin

Details

ALM

Output Connection: Optional.

(1)

Maximum 30V/100mA output

(2)

3.5 P5 - Tuning Port

EM870S has a tuning port with RS232 to modify the drive parameters, it’s only for tuning, not for equipment control
because neither precision nor stability is sufficient. If you need a field bus drive, use a Leadshine RS485 or EtherCAT
type drives:

The interface definition is as follows:

3.6 Status LED Lights

There are two LED lights for EM870S. The GREEN one is the power indicator which should be always on in normal
circumstance. The RED one is a drive status indication light, which will be OFF while working normally but ON and
flash 1 or 2 times in a 3-second period in the case of enabled over-current or over-voltage protection.
