5.3.4 Response times
The response time is the time between the detection of an input signal and the change of a
linked output signal. Below you will find information on the response times of the F-
TM ServoDrive drive system.
Note
The actual response time falls between a minimum and maximum response time. You must
always assume the maximum response time when configuring your system
.
The drive system is the component that provides the safety functions. The description "error-
free drive system" means that the component providing the safety functions itself has no
defect:
● Maximum response time in error-free drive system
When the enable is removed at the STO+ or STO- terminals, the maximum response
time in an error-free drive system is guaranteed.
Stop function (via terminals)
The following table specifies the response times for the indicated stop functions from the
time of activation until occurrence of the response.
5.4 Safety Integrated
Important notes on the Safety Integrated system are provided in this section.
Diagnostics hardware fault
If an internally diagnosed hardware fault occurs, you can only reset the module by restarting
it. Nevertheless, the replacement of the F-TM ServoDrive is strongly recommended.
Unwanted activation of the safety function can be an indication of a hardware fault.
Wiring the F-TM ServoDrive
For information on how to perform the electrical wiring for the F-TM ServoDrive, refer to
section Wiring (Page 20)
STO inputs
The STO inputs are described in the section Connecting safe torque off (Hardware STO)
(Page 27).
