Releasing The Failsafe Function "Safe Torque Off" (Sto) - Siemens SINAMICS G120C Getting Started

Defining the function of an analog output
Procedure
To define the function of an analog output, proceed as follows:
1. Select the function marked using a CO parameter.
2. Enter the number of the CO parameter into parameter p0771 of the analog output.
3. Use p0776[0] to determine whether the analog output is a current or voltage input.
You have now defined the analog output function.
Example: You want to output the signal for the actual current via AO 0.

Releasing the failsafe function "Safe Torque Off" (STO)

Precondition
Procedure
For releasing the STO function you have to set the following parameters:
1. p0010 = 95 - Enter commissioning of fail-safe functions.
2. p9761 = ... - Enter password for fail-safe function (factory setting = 0).
3. p9762 = ... - Enter new password, if required (0 ... FFFF FFFF).
4. p9763 = ... - Confirm new password.
5. p9601.0 = 1 - Select STO via terminal strip.
6. p9659 = ... - Set the forced checking procedure timer.
7. p9700 = D0 - Copy fail-safe parameters.
8. p9701 = DC - Confirm fail-safe parameters.
9. p0010 = 0 - Finish commissioning of fail-safe functions
10.p0971 = 1 - Save the parameters in a non-volatile memory
11.Wait until p0971 = 0
12.Bring the converter into a completely no-voltage condition (400V and 24V) and switch on
You have released the STO function.
