Safety functions integrated in the drive
5.2 Acceptance of the safety functions
F-TM ServoDrive
42 Equipment Manual, 02/2020, A5E47579503-AA
Requirements for the acceptance test
● The machine is correctly wired.
● All safety equipment (e.g. protective door monitoring devices, light barriers, emergency
limit switches) are connected and ready for operation.
● The commissioning of open-loop and closed-loop control must be complete; otherwise,
the over-travel distance may be changed due to a changed dynamic response of the
drive control, for example. This includes:
– Settings of the setpoint channel
– Position control in the higher-level CPU
– Drive control
Acceptance test
The acceptance test comprises two parts:
● You test whether the safety functions are set correctly in the drive:
– Does the configured safety function sufficiently reduce the residual risk at the
machine/plant?
– Do the set interfaces, timers and monitoring functions match the configuration of the
machine?
● You test whether the safety-relevant functions in the machine or system function
correctly.
This part of the acceptance test goes beyond the acceptance test of the drive:
– Is all safety equipment, such as protective door monitoring, light barriers and
emergency limit switches, connected and ready for operation?
– Do the drive settings match the configured safety-relevant function in the machine?
Documentation
The documentation consists of the following parts:
● Description of safety-relevant components and functions of the machine or system,
including the program versions.
● Report of the acceptance test results.
● Report of the safety function wiring.
● The documentation must be signed off by the person who performed the acceptance test.
