3.1.4 Traveling Limit Switch Input [LMT+/-]
Traveling limit switches are used to protect the system. This input signal is connected
via the photocoupler and RC filter. When the limit switch is applied, the external VEX

will be the power source of the photocoupler. This enables the over-trav-
eling function.

3.1.5 Position Latch [LTC]
This is a general purpose input pin for latching simultaneous position information.
Users can read the position counter by programming.
For detailed information, refer to the software manual.
3.1.6 Servo Ready Signal [RDY]
This is a general purpose digital input for checking the servo “ready” status from the
servo drive connection.
For example, the status can be verified before any command is issued. This input
can also be used as a general purpose input for other applications.
3.1.7 Home Position [ORG]
The home position defines the original position or home signal for each axis. For pro-
gramming settings, please refer to the software manual.
3.1.8 In-Position Signal [INP]
The in-position range (or deviation) is usually defined by the servo drive. When the
motor moves and converges in this range (or deviation), the servo drive will broad-
cast a signal to indicate that the motor is in the defined position.
