7-2-10 Installation for 2ch communication specifications with CNC, and installation of
only one power supply unit. (2-system control)
In this example, the following systems are explained. The same connection is used for other 2ch
systems.
• CH1: B-V14/V24/V14L + B-V14/V24/V14L
• CH2: B-V14/V24/V14L + A/B-SP
