System overview

The following figure shows a typical drive system with integrated functional safety design, comprising
the following components:
– motor controller CMMP-AS-...-M3,
– safety module CAMC-G-S3,
– synchronous servo motor, e.g. from the series EMMS-AS or EMME-AS from Festo,
– linear axle with second measuring system, e.g. EGC-...-M... from Festo,
– reliable clamping unit.

Fig. 2.2 Safety module functional principle
The actual drive control and function control of the axle of motion takes place as usual via the motor
controller CMMP-AS-...-M3 and the assigned control interfaces, e. g. [X1] or a fieldbus.
The safety module monitors the function of the drive controller of the motor controller. For this, the
safety-relevant variables of the motor movement are recorded and monitored according to the selected
safety functions. If the safety limits are exceeded (e.g. a maximum permissible speed), then the safety
module can, for example, safely switch off the driver supply for the output semi-conductor, thus pre­
venting the power output stage from supplying the energy required by the motor.
