What it means
C30716 is a safety message of the Safety Integrated (SI) motion monitoring. The drive issues it as SI Motion P2: Tolerance for safe motion direction exceeded
when the tolerance for the "safe motion direction" function — SDI, Safe Direction — has been exceeded. The drive is stopped as a result of the stop response configured in p9366. The message value tells whether the tolerated range was left on the positive or on the negative direction.
Why it appears
- The tolerance for the "safe motion direction" function was exceeded: the drive has moved beyond the tolerated range of the SDI monitoring, either in the positive or in the negative direction (the message value distinguishes the two).
- As a result of the exceedance, the drive is stopped with the stop response configured in p9366.
What to check
- Check the traversing/motion program in the control.
- Check the tolerance for the "SDI" function and, if required, adapt it in p9364.
Reading the message value
- The drive stores the message value in r9749; interpret it as a decimal number. On the G120, the message value is stored in r2124.
- 0 — tolerance for the "safe motion direction positive" function exceeded.
- 1 — tolerance for the "safe motion direction negative" function exceeded.
Parameters the manual names
- p9364 — SI Motion SDI tolerance: the tolerance of the SDI function; this is the setting to check and, if required, adapt for this message.
- p9366 — SI Motion SDI stop response: sets the stop response with which the drive is stopped when the SDI tolerance is exceeded.
- r9749 — SI message value: carries the value of this message (0 or 1, interpret as decimal); on the G120 the value appears in r2124.
- r2124 — alarm value: the parameter in which the G120 stores this message's value.
Acknowledging and restarting
The message can be acknowledged without a POWER ON (safe acknowledgment). Prerequisite: deselect the "SDI" function and, if required, select it again.
On the G130, G150, S120 and S150, carry out the safe acknowledgment via one of the following options: the TM54F, the onboard F-DI (only CU310-2), PROFIsafe or the machine control panel. On the G120, deselect the "SDI" function and select it again, then carry out the safe acknowledgment via "Acknowledgment internal event".
What differs between the drive families
Straight from the manuals' own fields — C30716 is not described identically everywhere.
| Drive family | Reaction | Acknowledge | Message class | Component | Manual |
|---|---|---|---|---|---|
| G130, G150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS G130, G150 List Manual · p. 1700 |
| S120, S150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS S120, S150 List Manual · p. 3008 |
| G120 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | — | SINAMICS G120 · p. 929 |
The drives this code lives on
C30716 is described for G120, G130, G150, S120, S150. These are the converters of those families in our catalogue — price on request.
Questions technicians ask
What does fault C30716 mean on a SINAMICS drive?
It is a Safety Integrated message: the tolerance of the safe motion direction (SDI) function was exceeded and the drive was stopped with the stop response configured in p9366.
How do I acknowledge C30716 without switching the power off?
Deselect the SDI function and, if required, select it again, then carry out a safe acknowledgment — via the TM54F, the onboard F-DI (only CU310-2), PROFIsafe or the machine control panel. On the G120, the safe acknowledgment is carried out via "Acknowledgment internal event".
Which parameter holds the SDI tolerance for C30716?
p9364. The remedy is to check this tolerance and adapt it if required, together with the traversing/motion program in the control.
What does the value 0 or 1 of C30716 tell me?
Read the message value as a decimal number: 0 means the tolerance for the "safe motion direction positive" function was exceeded, 1 means the negative direction. The value is in r9749, on the G120 in r2124.
