BECKHOFF AX2500 - Manual (Page 59)

8.14.4 Connection to a SSI encoder (X4)
You can set up the AX2500 as a slave following a synchronous serial absolute-encoder
(master-slave operation). This application uses the SubD connector X4.
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 MHz
AGND (terminal X3/1) must be connected to the ground of the control system!
8.14.5 Connection to stepper motor controllers (pulse and direction)
You can connect the servo amplifier to a third-party stepper-motor controller. The param-
eters for the servo amplifier are set up with the aid of the setup software (electrical gear-
ing). 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 limit frequency!
Using an A quad B encoder provides better EMC noise immunity.
