What it means
The drive shows C01716 with the title "SI Motion P1 (CU): Tolerance for safe motion direction exceeded". It is raised when the tolerance for the "safe motion direction" function — the manual expands SDI as Safe Direction (safe motion direction) — was exceeded in the Safety Integrated (SI) motion monitoring of the Control Unit. The drive is stopped as a result of the stop response configured in p9566. The message value states whether the tolerance of the positive or of the negative safe motion direction was exceeded. The descriptions for the G130/G150, the S120/S150 and the G120 are identical apart from the parameter in which the message value is read and the safe acknowledgment options.
Why it appears
- The tolerance for the "safe motion direction" (SDI) function was exceeded — per the message value, either for the "safe motion direction positive" or for the "safe motion direction negative" function.
- As a result, the drive is stopped with the stop response configured in p9566.
What to check
- Check the traversing/motion program in the control.
- Check the tolerance configured for the "SDI" function and, if required, adapt it in p9564.
Reading the message value
The drive stores the message value decimally: in r9749 (SI message value) on the G130/G150 and S120/S150, and in r2124 (alarm value) on the G120.
- 0: the tolerance for the "safe motion direction positive" function was exceeded.
- 1: the tolerance for the "safe motion direction negative" function was exceeded.
Parameters the manual names
- p9564 — SI Motion SDI tolerance (Control Unit): the tolerance of the safe motion direction function; check it for this message and adapt it here if required.
- p9565 — SI Motion SDI delay time (Control Unit): delay time of the SDI function, named together with p9564 and p9566 for this message.
- p9566 — SI Motion SDI stop response (Control Unit): the stop response the drive carries out when the tolerance is exceeded.
- r9749 — SI message value: read the message value of this message here, interpreted decimally (G130/G150, S120/S150).
- r2124 — alarm value: read the message value of this message here, interpreted decimally (G120).
Acknowledging and restarting
The message is acknowledged with a POWER ON. It can also be acknowledged without a POWER ON by safe acknowledgment: deselect the "SDI" function and, if required, select it again, then carry out the safe acknowledgment. On the G130/G150 and S120/S150 this is done using one of the following options: the Terminal Module 54F (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 — C01716 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. 1475 |
| S120, S150 | NONE | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | None | SINAMICS S120, S150 List Manual · p. 2695 |
| G120 | — | IMMEDIATELY (POWER ON) | Safety monitoring channel has identified an error (10) | — | SINAMICS G120 · p. 857 |
The drives this code lives on
C01716 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 C01716 mean on a SINAMICS drive?
It reports that the tolerance of the Safe Direction (SDI) function — the safe motion direction — was exceeded in the Control Unit's SI motion monitoring. The drive is stopped with the stop response configured in p9566.
How do I acknowledge C01716 without switching the power off?
Deselect the SDI function and, if required, select it again, then carry out a safe acknowledgment — via the Terminal Module 54F (TM54F), the onboard F-DI (only CU310-2), PROFIsafe or the machine control panel; on the G120 via "Acknowledgment internal event".
What does the message value of C01716 tell me?
Interpreted decimally, 0 means that the tolerance for the safe motion direction positive was exceeded and 1 that the negative direction was exceeded. The value is read in r9749 on the G130/G150 and S120/S150 and in r2124 on the G120.
Which parameter holds the tolerance monitored by C01716?
p9564, the SI Motion SDI tolerance. Check the traversing/motion program in the control first, then check this tolerance and adapt it if required.
