What it means
F07436 tells you that the actual value of the free tec_ctrl 0 has reached one of its limits. The drive obtains this actual value from the signal source set via connector input p11064. The fault value in r0949, interpreted as a decimal number, shows which limit was reached: 1 for the upper limit, 2 for the lower limit. The same condition can also be signaled as an alarm (A) instead of a fault, depending on the drive's configuration.
Why it appears
- The actual value of the free tec_ctrl 0 has reached its upper limit (fault value 1).
- The actual value of the free tec_ctrl 0 has reached its lower limit (fault value 2).
- The monitored actual value comes from the signal source set via connector input p11064.
What to check
- Adapt the limit settings to the actual value signal: set the upper limit in p11067 and the lower limit in p11068.
- Check the scaling of the actual value signal.
- Check the signal source setting for the actual value in p11064.
Reading the message value
- Fault value in r0949, interpret decimal: 1 — the actual value has reached the upper limit.
- 2 — the actual value has reached the lower limit.
Parameters the manual names
- p11064 — connector input (CI) that selects the signal source of the free tec_ctrl 0 actual value; check this setting when the fault appears.
- p11067 — upper limit of the free tec_ctrl 0 actual value; adapt it to the actual value signal.
- p11068 — lower limit of the free tec_ctrl 0 actual value; adapt it to the actual value signal.
- r0949 — fault value; read it as a decimal number to see whether the upper (1) or the lower (2) limit was reached.
Acknowledging and restarting
Acknowledge the message immediately. Once the limits in p11067 and p11068 match the actual value signal and the signal source in p11064 is set correctly, the drive can be started again.
The same on every family
Every manual that describes F07436 gives it the same reaction, acknowledgement and message class.

Questions technicians ask
What does fault F07436 mean on a SINAMICS G120XA?
The actual value of the free tec_ctrl 0 has reached its limit. Fault value r0949, read as a decimal number, shows whether it was the upper limit (1) or the lower limit (2).
Which parameters should I check for F07436?
Adapt the limit settings in p11067 (upper limit) and p11068 (lower limit) to the actual value signal, check the scaling of the signal, and check the source selected in p11064.
Can F07436 also appear as an alarm?
Yes, the same condition can also be signaled as an alarm (A) instead of a fault.
How is F07436 cleared?
Acknowledge the message immediately. After the limits and the signal source have been matched to the actual value signal, the drive can be restarted.
