13.6 Connector: encoder [X2B]
Different types of encoders can be connected to the 15-pin D-Sub connector (see section
12.5 Encoder connector [X2B] on page 220):
l Analogue incremental encoders (1 V
ss
)
l Incremental encoders with a serial interface (RS485 level, e.g. EnDat,
HIPERFACE
®
, BISS)
l Digital incremental encoders (RS422, HALL sensors)
It is also possible to evaluate an optional error signal (AS/NAS) via pin 6. With some
incremental encoders, it is possible to detect and signal soiling or other
faults/malfunctions of the measuring system via an output (AS or NAS). The error signal
can be evaluated by digital as well as analogue incremental encoders.
In the case of analogue incremental encoders, the evaluation is only possible if no
commutation track (Z1) is parameterised and connected. The evaluation of the error signal
can be inverted.
Configuration on the device [X2B]
D-SUB connector, 15-pin type, female
Mating connector [X2B]
l D-SUB connector, 15-pin type, male
l Housing for a 15-pin D-SUB connector with locking screws of type 4/40 UNC
Damage to property caused by an incorrect power supply
If an incorrect power supply is used, the encoder may be destroyed. Ensure that the
correct voltage is activated prior to connecting the encoder to [X2B].
To do so, start the MetronixServoCommander
®
parameterisation software and select
the Parameters/Device parameters/Angle encoder settings.
