2.4.4 I/O Connector (CN1)
Input and output signals of the drive are all photocoupler protected. The signal status of
internal photocouplers [ON: conduction], [OFF: Non-conduction], are not displaying the
voltage levels of the signal.

2.4.4.1
Limit and origin input signal
Connect limit sensor and origin sensor to IN/OUT connector of LIMIT+, LIMIT-, ORIGIN pin.
LIMIT+ and LIMIT- sensor works to limit each axis of rotation range to CW and CCW direction,
using for protection of mechanical collision or others. ORIGIN sensor uses to assign the
origin of the mechanisms.
2.4.4.2
Brake and Output signal
Brake function prevents motor rotation under Servo OFF Status by BRAKE+/BRAKE- pin of
I/O Connector (2.4.4 I/O Connector). BRAKE+ is +24 V externally supplied to operate brake
circuit and BRAKE- is the output signal for actual motor control. Control signal automatically
generates according to Servo ON/OFF status and alarm generation.
