2.2 List of parameters
SINAMICS G120C
238 List Manual (LH13), 04/2014, A5E33840768B AA
Description: Sets the mode to change over the master control / LOCAL mode.
Value: 0: Change master control for STW1.0 = 0
1: Change master control in operation
Danger: When changing the master control in operation, the drive can manifest undesirable behavior - e.g. it can accelerate
up to another setpoint.
Description: Displays whether writing to parameters is inhibited.
r3996[0] = 0:
Parameter write not inhibited.
0 < r3996[0] < 100:
Parameter write inhibited. The value shows how the calculations are progressing.
Index: [0] = Progress calculations
[1] = Cause
Note: Re index 1:
Only for internal Siemens troubleshooting.
Description: Sets activation/de-activation of the "auto tuning" function.
To permanently save the values that have been set, the parameters must be saved in a non-volatile memory (p0977
= 1).
The individual measuring steps can be configured in the following parameters:
p5301 for "One Button Tuning" (p5300=1) - this function is being prepared
p5302 for "Online Tuning" (p5300=2)
Sets activation/de-activation of the "onlinetuning" function. The following parameters are written to when online
tuning is activated: p430, p1160, p1400, p1413 - p1426, p1428, p1429, p1433 - p1435, p1441, p1460 - p1465,
p1498, p1513, p1656 - p1676, p2533 - p2539, p2567, p2572, p2573, p5280
Value: -1: Reset (restore default values)
0: Inactive
1: One Button Tuning
2: Online Tuning
Dependency: The prerequisite for the "auto tuning" function is that the "Moment of inertia estimator" function module is activated
(r0108.10).
Refer to: p5301, p5302
Warning: Only the motor measuring system is taken into account when optimizing the position controller. If an external
measuring system is used for the position control, then this can result in an unstable controller setting.
