Notes with regard to a typical circuit:
–
The safety switching device used must switch off the controller enable (X1-9, DIN5) without a delay
and the inputs STO-A and STO-B (X40-1, -3) with a delay.
–
The required delay is application-dependent and must be defined specific to the application
concerned. The delay must be designed so that the drive is decelerated to zero, even at maximum
speed, via the quick stop ramp in the CMMP-AS...-M3, before STO-A/B are switched off.
–
The electrical installation is executed in accordance with the requirements of EN 60204-1.
For example, the safety switching device and the motor controller are located in the same control
cabinet, so that faults can be excluded for a cross-circuit or earth fault between the cables
(acceptance test on the control cabinet for faultless wiring).
–
The typical circuit exhibits a 2-channel structure, which is suitable for categories 3 and 4 with
additional measures.
–
Which additional measures are required depends on the range of applications and the safety
concept of the machine.
