7.3.1 External DC 24 V voltage supply for group stop
When multiple frequency inverters should be switched off by on DC 24 V voltage
supply, the overall current consumption of the STO inputs must be determined.
Please check the operating instructions for the current consumption.
Typical is 10 mA for each STO input for each device.
Dimension the cable cross sections according to the calculated current in compliance
with the maximum connectable cable cross sections.
7.4 DC 24 V power supply by AGL
You can use terminal X11.1 (DC 24 V supply) and X11.2 (GND) in order to supply a
safety control device. Only use the power supply for the device connected to the
frequency inverter. Other safety control devices must not be connected. The maxi-
mum output current is 100 mA.
All further connected components (in example displays of digital outputs) and the
safety control device must not have higher current requirements.
8 Requirements to be met in operation
During operation, the projected and commissioned machine components must not be
changed. If the machine is modified a new acceptance inspection is required.
Check the safety function at regular intervals. The test intervals are to be determined
according to the risk analysis. However, the check should be performed once every
year, at the latest.
9 Requirements to be met by acceptance inspection
The acceptance inspection of the safety function is ordered by the manufacturer of
the machine. The inspection (acceptance, validation) shall be performed by a proper-
ly qualified person.
The result of the inspection is to be documented and must be signed by the inspec-
tor. Each safety function must be documented in detail in this report.
The inspections also include the machine documentation, including its safety func-
tions. The safety functions must be checked particularly during the inspection and
documented in the inspection report. Parameter settings shall be attached to the
report. Further documents shall be added, as required, depending on the machine.
Depending on the result of the risk analysis, inspection reports of the regular inspec-
tions shall be issued and signed by the inspector.
10 Application Examples
The following examples illustrate how the functions “Safe Torque Off (STO)” and
“Safe Stop 1 (SS1)” work. According to EN 60204, stop functions are divided in dif-
ferent categories. By suitable safety control devices, stop categories 0 and 1 can be
realized in combination with the frequency inverter ACU.
