RS422 mode

Notice

Differential and single-ended connection

The RS422 signal transmits a differential voltage, which makes the signal less sensitive to interference compared to a single-ended signal.

If the encoder signal is to be transmitted over longer distances or at higher frequencies, an encoder with RS422 signals is recommended.

Shielded and twisted pair cables should be used.

Connection of RS422 encoders without zero pulse in two-channel mode

	Connection instructions In two-channel mode only encoders without zero pulse C can be used. The module pins for the C track are assigned the signals of the second A track. Both encoders are powered via module pins 22 and 24. Make sure that the sum of the supply currents does not exceed the sum current of 0.3 A.

	Connection instructions If a counter / pulse generator is connected, the B track determines the counting direction. In RS422 mode a differential signal is expected on the B̅ track. Only counters / pulse generators without zero pulse are suitable for use in two-channel mode. The module pins of the C track are assigned the signals of the second A track. Both encoders are powered via module pins 22 and 24. Make sure that the sum of the supply currents does not exceed the sum current of 0.3 A.
