2 Product description of safety module CAMC-G-S3
These output signals can be transmitted to the function controller as a status signal. They
can be used to activate external safety switching devices via safe outputs. For example,
an external clamping unit can be activated.
Safety functions for motion monitoring also use the safely-detected speed (ACTUAL_SPEED) or a safely-
detected position (ACTAL_POSITION) for monitoring. They control the approved speed in the functional
section of the motor control via a speed limit (SPEED_LIMIT).
The safety functions are configured using a series of parameters. The following can be set:
– speed ramps,
– monitoring limits for speed and position,
– time delays.
Additional settable options are:
– the behaviour for restart.
– the way in which the safety module manipulates operation of the basic unit:
– it does not manipulate actively and only monitors.
– it activates the quick stop in the basic unit and causes the basic unit to perform a quick stop
whilst monitoring the braking operation.
– it actively regulates the speed in the basic unit downwards and, at the same time, monitors com­
pliance with the limit values.
EN 61800-5-2 defines the various safety functions for drive controllers. It also defines
three methods for monitoring braking. Through the above configuration, the safety mod­
ule can support all the methods listed in the standard.
The safety module supports the safe stop and movement functions described in the fol­
lowing sections, in accordance with è Section 2.2.3, Tab. 2.4.
