[8] Wiring of origin signal
(1) When this signal is used in an open loop
When the differential signal origin (Z phase) signal is output from the driver
When connecting an open collector type origin signal
(2) When this signal is used in a closed loop
Wire the feedback signal (signal from the encoder) from the driver as shown below.
The driver (encoder) will not pose any problems if it can output a signal equivalent to AM26LS31.
• For details on the signal level on the driver side, check with the driver manufacturer.
