3.6 External devices description
AC-M1 can be connected to the following external devices.
3.6.1 Encoder
A Hall-effect 64-pulse quadrature encoder manufactured by SME is coaxially enclosed in
the AC motors in order to provide a closed-loop control of the torque and the speed (see
the appendix “General technical overview of SME technology” for more details).
AC-M1 control board provides both a 5V power supply (pin K2-1) and a 12V power supply
(pin K1-21).
Both these power supplies are referenced to a dedicated ground terminal (pin K2-9).
To increase immunity use shielded cables and keep them separated from power leads.
Channel A has to be connected to pin K2-5 and Channel B to pin K2-4.
The environmental protection rating is IP65.
If you need to make use of other types of encoder, please contact SME in order to verify
the technical feasibility.
