2.8.2 Danger due to electricity
2.8.3 Dangers due to magnetic fields (effects on medical implants)
2.8.4 Danger due to high temperatures
2.8.5 Mechanical hazards
DANGER
Danger! Risk of electric shock!
If work on electrical components is required, ensure that the work is carried
out properly, failure to do so will cause serious or fatal injuries.
Work on the machine's electrical equipment may only be performed by
skilled electrician or trained personnel under the supervision of a skilled
electrician in accordance with all relevant electrical regulations.
DANGER
Danger due to strong magnetic fields.
The built-in permanent magnet creates strong magnetic fields around the
module,
which can influence medical implants such as pacemakers or
defibrillators or impair their function.
Persons with a pacemaker must keep a safety distance of at least 10 [cm].
CAUTION
Danger of burns due to heated housing!
The housing of the module can reach a temperature of approx. 60°C at a
room temperature of 20-25°C during operation. This temperature continues
to rise the higher the ambient temperature is.
Do not touch the housing or wear protective gloves.
No temperature-sensitive parts must be in contact or fastened.
Allow the housing to cool down to ambient temperature before touching it
without protective gloves.
CAUTION
Danger of injury by moving components!
Limbs can be crushed by moving components!

Work on and with the module may only be carried out by qualified
personnel.
Never reach into the system during normal operation!

3.4 Module loads
3.5 Positioning time
The travel time diagram refers to centric loads. Depending on the required
position tolerance, the settling time must be added to the travel time shown in
the diagram.
The table next to the diagram shows the load-dependent maximum settling
time* for a position tolerance of ±0.1° and ±0.015°. The values given apply to a
waiting time of 25ms. In the delivery state, the settling timeout is configured to
100ms. This means that it may have to be adjusted depending on the position
tolerance and load.
With a required position tolerance of ±0.4°, the drive is already stable within the
tolerance window at the end of the travel time, independent of the load. I.e. the
waiting time can be set to 0ms and the positioning time thus corresponds to the
travel time.
The precise swivel time calculation can be determined via the online
engineering tool Afag PerfectCycle ➡www.perfectcycle.afag.com.

5.2 Product description
The SREH-50-IOL module is a highly compact electric smart rotary module for
rotating payloads.
The controller integrated in the rotary module is controlled via a 5-pole IO-Link
and is equipped with two separate, galvanically isolated supplies - one supply
each for the logic and one for the motor.
The SREH-50-IOL can rotate endlessly and is equipped with an absolute
encoder with 4-fold multiturn.
As no external controller is required, the smart rotary module is simply
connected via a connecting cable from the SREH-50-IOL to the IO-Link master
provided by the customer. This connecting cable is used for both power supply
and signal exchange.
Further technical information can be found in the chapter 3 “Technical data” in
these installation instructions.
