Mounting A Motor Feedback System With Spring Plate Stator Coupling; Electrical Installation; Shielding Connection - SICK STEGMANN SFS60S Instrucciones De Uso

NOTE
For variants with a spring plate stator coupling, it may not be possible to hold
the torque wrench perpendicular to the screw. An angle of inclination of up to
20° is included in the tightening torque tolerance. Loosening and fixing the
screw at an angle on a regular basis can cause damage to the screw.
WARNING
Note the following safety notes for screws used during mounting:
• Minimum strength class of 8.8
• Select the screw length type according to the mounting conditions
• Secure screw connections from loosening using screw adhesive
Spring washers and toothed washers are not sufficient for securing
•
screws!
WARNING
Only use the screws once. After removing the motor feedback system:
Clean the residue off of the affected threads on the drive shaft.
b
Use a new (unused) screw with screw adhesive on the thread during the
b
remounting process.
If the Torx screw (4) is lost, another must be purchased from SICK.

Mount on the drive shaft (2) provided by the customer with supplied feather
b
key (1).
Block the customer's drive shaft (2).
b
Apply screw adhesive to the thread of the clamping ring (3) or the supplied
b
Torx screw (4).
Insert the Torx screw (4) in the clamping ring (3) and secure it loosely; do not
b
tighten it at this stage.
Push the motor feedback system onto the customer drive shaft (2), aligning
b
it with the feather key (1). Ensure that you take the distance between the
spring plate stator coupling (5) and the mounting surface (6) into account
when it comes to the length of the screws (4).
Secure the screws (7) and the washers (8) loosely and apply screw adhesive
b
to each thread at the same time.
Fasten the screws (7) until the motor feedback system can be fully pushed
b
on and the spring plate stator coupling (5) is resting against the mounting
surface (6).
Tighten the screws (7). Tightening torque: 1.2 ± 0.1 Nm.
b
Tighten Torx screw (4). Tightening torque: 3.5 ± 0.1 Nm.

4.3 Mounting a motor feedback system with spring plate stator coupling, long
Fig. 2: Mounting a blind/through hollow shaft
1. Mount on the drive shaft (2) provided by the customer with supplied feather
key (1).
2. Block the customer's drive shaft (2).
3. Apply screw adhesive to the thread of the clamping ring (3) or the supplied
Torx screw (4).
4. Insert the Torx screw (4) in the clamping ring (3) and secure it loosely; do not
tighten it at this stage.
5. Push the motor feedback system onto the customer drive shaft (2), aligning
it with the feather key (1) so that the long spring plate stator coupling (5) is
resting against the mounting surface (6).
6. Mount the long spring plate stator coupling (5) using at least one M4 screw
(7) and a washer (8), and apply screw adhesive to the thread at the same
time.
7. Tighten the screw (7). Tightening torque: 1.2 ± 0.1 Nm.
8. Tighten Torx screw (4). Tightening torque: 3.5 ± 0.1 Nm.

Electrical installation

NOTE
Observe the corresponding operating instructions of the external drive system
or the higher-order control system for the installation of the motor feedback
system.
NOTE
Make sure the affected machines/systems are in a de-energized state during
mounting!

5.1 Shielding connection

NOTE
A suitable encoder shield connection to the ground or to the motor shield is
required for smooth operation.
With the motor feedback system with spring plate stator coupling (Fig. 1, 2),
this is ensured using the spring plate stator coupling (5).
5.2 Motor feedback system signals
The motor feedback system has the following signals:
HIPERFACE interface:
®
US supply voltage; the supply voltage is between + 7 V and +12 V, the rec‐
•
ommended supply voltage is +8 V.
GND - ground connection; electrically isolated from the housing. The voltage
•
drawn is US.
+ SIN process data channel; sine signal of 1 Vpp with a static offset of REF‐
•
SIN.
