Safety module replacement

6.1.1

Repair

Repair of the module is not permissible. If necessary, replace the complete module.
6.1.2

Removal and installation

Information on removing and installing the safety module can be found here:
– Mounting/dismounting the safety module è Section 3.1.
– Accept the serial number of the replaced safety module è Section 4.3.2.
6.2

Decommissioning and disposal

Observe the information for dismantling the safety module in Section 3.1.
Disposal
Observe the local regulations for environmentally appropriate disposal of electronic
modules.
6.3 Replacing the previous series CMMP-AS with the CMMP-AS-...-M3
CMMP-AS
The devices of the previous CMMP-AS series have an integrated STO “Safe Torque Off” in accordance
with EN ISO 13849-1, Cat. 3 / PLd. The two-channel arrangement required by the STO function is
achieved via two separate switch-off paths:
– 1. Switch-off path: Output stage enable via [X1.21], switch-off of the power output phase
(PWM signals disabled). The power semiconductor drivers are no longer activated by pulse patterns.
– 2. Switch-off path: Power supply to the six output stage power semiconductors IGBTs via [X3] is
interrupted by means of a relay. The driver supply for the power semiconductors (IGBT
optocouplers) is disconnected by means of a relay. This prevents the pulse pattern (PWM signals)
reaching the power semiconductors.
The CMMP-AS also has a floating feedback contact ( [X3] Pins 5 and 6) which, as a diagnostics output,
indicates the presence of the driver supply.
