3.1 Encoders connectors
3.1.1 Connector JC5: Analog position encoder (1Vptp, EnDat 2.1)
Caution: The encoder cable must be insulated (no contact) from the power and the mains.
The inputs and outputs of this connector are not galvanically insulated from the GND.
The inputs and outputs must be connected to an Extra Low Voltage circuit only
(SELV).
Caution: The encoder connector must be handled in an ESD protected environment, only.
Remark: The encoder cable(s) connected to the DSC2P must be shielded (see §3.7.1
).
Two different types of encoder can be connected to the analog encoder connector: either an
incremental analog encoder 1 Vptp or an analog absolute encoder (EnDat 2.1).
3.1.1.1 Incremental analog encoder (1 Vptp)
The incremental analog encoder has 1 Vptp signals with a load resistor R
0
=120Ω. It determines the motor
position thanks to two sinusoidal signals with a 90° phase-shift (sine and cosine). A third signal, the index (also
called reference mark), gives the absolute motor position:
The +5VDC encoder supply output is protected by the fuse F3 (1A) on JC5, JC6 and JC10.
Remark: Refer to the corresponding ’Operation & Software Manual’ for more information about the use
of EHO and ELS signals. The EHO signal is only present from the DSC2Pxxx-xxxC.
