SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013

Example:

For a 12 ms SI monitoring cycle and a switching frequency of 110 ms (p10017 = 0), the maximum discrepancy time

which can be set is as follows:

p10002 <= (110/2 ms) - 12 ms = 43 ms

Rounded-off, p10002 <= 36 ms is obtained (since the discrepancy time can only be accepted as a whole SI moni-

toring cycle, the value will need to be rounded up or down to a whole SI monitoring cycle if the result is not an exact

multiple of an SI monitoring cycle).

Note:

F-DI: Failsafe Digital Input

A01796 (F, N) SI P1: Wait for communication

Reaction: NONE

Acknowledge: NONE

Cause: The drive waits for communication to be established to execute the safety-relevant motion monitoring functions.

Note:

In this state, the pulses are safely suppressed.

Alarm value (r2124, interpret decimal):

3: Wait for communication to be established to PROFIsafe F-Host.

Remedy: If, after a longer period of time, the message is not automatically withdrawn, the following checks have to be made:

- Check any other PROFIsafe communication messages/signals present and evaluate them.

- check the operating state of the F-Host.

- Check the communication connection to the F Host.
