11 – CONNECTION AND ENCODER TYPES FOR SYNCHRONOUS
MOTORS
PERMANENT MAGNET SYNCHRONOUS MOTORS (PMSM) will only work in closed loop.
EnDat
®
absolute or incremental sine-cos type, 2048 pulse/rev. encoders fitted to the motor shaft are
normally recommended for synchronous motors.
The encoder board must be inserted inside the inverter:
NXOPT-BE
or
NXOPT-BB
The board must be inserted in the 3rd connector from the left (slot C)
To connect the ECN 113 or ECN 413 Heidenhain encoder to the inverter, use the following table.
To connect sine-cos encoders (for example Heidenhain ERN1387), use the following table as well, but
ignore the first 4 connections (DATA+,DATA-,CLOCK+,CLOCK-) because they don’t exist in this kind of
encoder.

6 A- Yellow / Black
7 B+ Blue / Black
8 B- Red / Black
9 GND White / Green
10 Encoder power supply Brown / Green
In special circumstances, an incremental PUSH-PULL type encoder can be used; see paragraph 10 for
instructions on how to connect it.
The encoder must have a high number of pulse/revs, such as 10,000 for example.
ADVICE FOR ALL THE ENCODER TYPES
The encoder cable must be shielded, and the shield connected (as indicated in paragraph 3.2) to the
inverter ground terminal. In any event, the encoder should have a shielded cable of length sufficient
to allow connection direct to the inverter, following the shortest possible run and located WELL
AWAY FROM THE POWER CABLES. Remaining wires have to be isolated one by one and left
unconnected.
