9. PC/Teaching Pendant Connection Method in Multi-axis Configurations
This section explains the method to permanently connect a PC/teaching pendant in configurations consisting of
multiple axes, so that the PC/teaching pendant connector need not be removed/inserted each time.
The connector is connected to a SIO converter, and the SIO converter sends/receives data to/from each
controller via RS485 serial communication.
The basic specifications are as follow:
[1] Maximum number of connected axes: 16
[2] Maximum length of serial communication cable: 100 m or less
[3] Terminal
resistor: 220 : (Be sure to install a terminal resistor for the last axis to prevent the effect of
radiating noise.)
9.1 Connection Example
Caution: y Do not connect the teaching pendant and PC at the same time.
If both are connected at the same time, a communication error (message level) will occur.
y Use 0 V commonly for all devices to which 24 V is connected.
y Turn the 24-V power supply ON/OFF on the 24-V side only (do not disconnect 0 V).
