Installation of the shaft encoder
4.2.19.1 Shaft encoder on the control device (A7)
When connecting a shaft encoder, always observe the
supply voltage (5V / 24V) and the interface type (RS422 /
HTTL).
The power supply of the shaft encoder connected to
this bushing (A7) takes place directly via the control
device.
