SS1 / STO Implementation using a Safety Control Unit (Stop Category 1):
The example below shows Safe Stop (SS1) implementation that brings a motor to rest in a controlled
manner, before invoking STO on the drive after a time delay determined by an external Safety Control Unit.
The Safety Control Unit shown in this example is a Sick UE410-MU module. This configuration conforms to
SS1 as defined in EN 61800-5-2:2017 para 4.2.3.3 c). Other products are available on the market that may
better suit user’s application, so the user must select and assess appropriate equipment:
Configuration Setup:
TH1
Motor Thermistor ‘+’ connection
TH2
Motor Thermistor ‘-’ connection
DX1 Run Forward: 24 V digital input
DI4 Stop: 24 V digital input
STOA 24
V input connected via ‘
Safety Control Unit
’ DODE o/p signal
STOB 24
V input connected via ‘
Safety Control Unit
’ DODE o/p signal
Note: The maximum input level of STOA & STOB inputs is 25.2 V. This must be taken into
consideration when selecting a 24 V power supply to generate VCC, i.e. VCC(max) < 25.2 V.
On system power-up:
1. The Safety Control Unit outputs are de-energized (open-circuit), so STO on the drive is invoked
(active).
To run the drive:
1.
Ensure that the ‘Safety Demand’ is reset, i.e., contacts are closed.
2.
Close the ‘Start PB’ switch to ensure the Safety Control Unit is reset. This should enable outputs
Q3 & Q4, applying 24 V onto STOA & STOB inputs, and hence disabling the STO function.
