1) Differential line driver output rotary encoder
11.10.3 Cautions for the other side device
Encoders having the output forms shown in the following table can be connected to the terminals. (The
encoders may not function correctly depending on electrical compatibility. Check the specifications in
advance.)
Voltage output type encoders and absolute encoders cannot be connected to the high-speed counter input
terminals.
