5.5 Response for a communication failure via PROFIsafe or to the TM54F

5.5 Response for a communication failure via PROFIsafe or to the
TM54F
Factory setting for the response to communication failure
In the following cases, the drive responds with a STOP A.
● PROFIsafe communication to the higher-level control has failed.
● DRIVE-CLiQ communication to the TM54F has failed.
5.5.1

STOP B as response to communication failure with PROFIsafe control

If, for a communication failure, the axis coasting down can result in subsequent damage, as
response to the communication failure, instead of a STOP A, you can select that the axis is
stopped along a ramp.
Precondition
You have enabled Safety Integrated Extended Functions or Basic Functions.
Communication failure
In this context, communication failure can mean the following:
● Interruption or disturbance in PROFIsafe communication
● The higher-level controller (F-CPU) is in the STOP state
Drive response
Parameter p9612 defines the drive stop response when PROFIsafe communication fails:
● p9612 = 0: STOP A
● p9612 = 1: STOP B
Not e
For the selected STOP B stop response, in order to ensure that the OFF3 ramp is actually
maintained, when just using the Safety Basic Functions, the following must be carefully
observed:
• The STOP F to STOP A (p9658, p9858) transition time must be set to greater than or
equal to the SS1 delay time (p9652, p9852).
• If a higher-level control system responds to the drive fault by withdrawing the controller
enable signals, for faults F01611 and F30611, the message type must be changed to
alarm (p2118, p2119).
