WARNING
Risk of injury when the machine/system moves
unexpectedly!
Switch off power supply.
NOTICE
Malfunctions due to mechanical stress in the housing

Observe the requirements for the evenness of the mounting
surface.
The values relate to the entire bolting surface.

Depending on the load, the STM develops a very large heat
quantity that needs to be dissipated:
Mount the motor on heat-conducting materials.
To achieve the IP protection class 40:
Design the connection structure so that no chips, cooling
water or dirt can enter the STM's connection area from the
working area.
Note
•
If the unit has to be referenced via the measuring system's
index track, and if the moving range is limited when the STM
is installed, make sure that the basic carrier is aligned
correctly in the machine. (see Figure 5, page 28)
•
After every switch-on the controller moves jerkily about 30°-
40° anti-clockwise and about 30°-40° clockwise
Check the evenness of
the bolting surface
