G120C_PN fault code F30665 & F1665

Hi,
I have a 6SL3210-1KE21-7AF1 (G120C_PN) with firmware 4.7 SP6 HF5 (4708319) that has a permanane F30665 and F1665 fault.

I'm using STARTER 5.3.0.3 to commission the unit with the following procedure:

* Standard drive control [1]
* Standard I/O with analog setpoint and safety [13]
* IEC induction motor 4kw
* Constant load application [0]
* Identify the motor at standstill [2]
Params were then downloaded and copied RAM to ROM.

* Functions -> Safety integrated: Basic functions via onboard terminals
Safety params were then downloaded and copied form RAM to ROM.

Unit was then power cycled (mains on-off-on).

I now have persistant faults F30665 & F1665.

I tried following the information in this link and upgraded the G120C_PN firmware from 4.7 SP3 HF2 (4706404) to 4.7 SP6 HF5 (4708319) which is now the current firmware, but the problem persists.

If I repeat the setup with Standard I/O with analog set[point [12] (no safety) the result is the same.

Can you advise if this is a firmware issue and / or a possible solution?

I have attached the setting clipboard data.

Thanks!

Hello MattKtek,

if the fault comes from the Safety configuration you could try and disable Safety according to https://support.industry.siemens.com/cs/document/109757227, chapter 5.6

In case this does not solve the issue, please contact the technical support: https://support.industry.siemens.com/my/ww/en/requests/#createRequest

Hi Tech Team,
Thanks for the advice.

In G120C_PN->Control_unit->Functions->Safety Integrated, I reset the Safety Integrated to 'No Safety Function'  and power cycled. The faults F30665 & F1665 are no longer present but I cannot run the drive because the device is now in the operating state 'Switching on inhibited - supply STO terminal w/ 24V (hardware)'. See attached screenshots .

With nothing to go on, I tried suppying 24V to DI0, then DI4 & DI5, then finally DI0 & DI4 & DI5 to no avail. See attached screenshots.

I then upgraded the firmware to the latest version 4.7 SP10 HF5, factory defaulted the device, then recommissioned the device in 'std I/O with analog', reset the safety integrated to defaults, then power cycled. Still the same warning: 'Switching on inhibited - supply STO terminal w/ 24V (hardware)'

This was repeated with 'std I/O with analog and safety', still the same.

What I cannot understand is why I have the Switching on inhibited - supply STO terminal w/ 24V (hardware) warning when I have selected the No Safety Function in Functions>Safety Integrated?

To prove that the above process should actually work, I commissioned another G120C, a 6SL3210-1KE11-8AF1, using std I/O with analog(no safety), with the No Safety Function selected in Functions>Safety Integrated. This device works perfectly and does not bring up the warning Switching on inhibited - supply STO terminal w/ 24V (hardware).

 Hi Tech Team,
I did try a factory reset, several times as I was trying different things out but that didn't resolve the problem either.

The FAQ you mentioned in the first post is for the G120 modular -> This is a very strange behavior that it appears on this G120C.

I did notice that the post applies to the G120 modular, but I thought it might have some relevance so that's why the firmware was upgraded on the G120C.

Thanks for all your advice anyway. You can close this thread now. ;-)

hello, did you resolve your problem, please? I have the same to the same problem.

 And what is your problem? What inverter? What is the FW version? Do you have a picture of the diagnostics buffer of the VFD?
