Connection to a SSI encoder (X5)
You can set up the AX2040/2070 as a slave following a synchronous serial absolute-encoder
(master-slave operation). This application uses the SubD connector X5.
If lead lengths of more than 50 m are planned and for questions concerning the power supply of the
encoder, please consult our customer service.
Frequency limit: 1.5MHz
AGND and DGND (connector X3) must be joined together!
8.12.5
Connection to stepper-motor controllers (step and direction)
This interface can be used to connect the servo amplifier to a third-party stepper-motor controller.
The parameters for the servo amplifier are set up with the aid of the setup software (electrical gea-
ring). The number of steps can be adjusted, so that the servo amplifier can be adjusted to the
pulse-direction signals of any stepper-motor controller. Various monitoring signals can be output.
Observe the frequency limit!
Using an A quad B encoder provides better EMC noise immunity.
