Because of EMC reasons, the last component that handles the encoder signals should have a termination resistor when Sin/Cos or
TTL type encoders are used. The termination resistor enhances the quality of the signals. If there are no components on the encoder
signal chain after the Advanced safety option board, the termination must be on the Advanced safety option board.
If the Advanced safety option board transmits the encoder signals to the encoder board in slot C, use termination on the encoder
board and not on the Advanced safety option board. This applies to the cases in Illustration 10 and Illustration 11. It also applies to
other possible components that handle the encoder signals.
Do not use multiple termination resistors. Configure the termination resistor during the parameterization of the Advanced safety
option board.
Advanced safety option board
TTL: A+, B+, Z+
Sin/Cos: Sin+, Cos+, Ref+
TTL: A-, B-, Z-
Sin/Cos: Sin-, Cos-, Ref-

The use of resistor on the Advanced safety option board is selected during parameterization.
