Electrical installation
WARNING
Switch off the power of all affected machines/systems/vehicles during the
installation process.
When connecting the DFS60S Pro, observe the operating instructions of the
higher-level evaluation system.
Ensure that the screened connection is applied neatly.
Connect the housing or screen to ground. For this purpose, connect the
cable screening braid over a large area.
Only use screened and twisted-pair cables. All signal cables/interface sig‐
nals must be twisted in pairs with the appropriate complementary signal.
Protect the stator coupling against any strain caused by the connecting
cables. Observe the smallest permitted bend radius of the connecting
cables (permitted bend radius for encoder with cable outlet: min. 7.5 × outer
diameter of the cable).
Use a cable that is suitable for the application and the application condi‐
tions.
We recommend that you use SICK accessory cables (see corresponding data
sheets).
Provide the encoder with supply voltage generated using PELV systems
(EN 50178) (pollution degree 2).
The current for the power supply unit used for the encoder must be limited
externally to max. 1 A – either by the power supply unit itself or using a fuse.
Perform differential evaluation of the encoder signals.
Terminate used and unused encoder signals differentially; i.e., insert a termi‐
nating resistor of ≥ 120 Ω between the signal and the complementary signal.
In encoders with a connector outlet, do not pass on unused signals. Termi‐
nating is not required here.

6.2 Encoder signals
The DFS60S Pro is equipped with the following signals:
•
Supply vUS of the encoder: The supply voltage range measured on
the encoder is between 4.5 V and 32 V.
•
Ground connection GND of the encoder: Galvanically isolated from the hous‐
ing. The voltage relating to GND is +US.
•
Process data channel SIN+: SIN+ is a sine signal of 0.5 V
PP
with a static off‐
set of 2.5 V.
•
Process data channel SIN–: SIN– is a sine signal of 0.5 V
PP
with a static off‐
set of 2.5 V. SIN– is complementary to the SIN+ signal.
•
Process data channel COS+: COS+ is a cosine signal of 0.5 V
PP
with a static
offset of 2.5 V. The COS+ signal is phase-shifted by 90° in relation to the
SIN+ signal.
•
Process data channel COS–: COS– is a cosine signal of 0.5 V
PP
with a static
offset of 2.5 V. COS– is complementary to the COS+ signal.
•
Zero pulse Z: Z outputs the zero position of the encoder as a differential digi‐
tal signal with a width of 90° electrical (el.) and a level of 1.75 V (low) and
2.9 V (high).
