r3996[0...1] Parameter write inhibit status / Par_write inhib st
Access level: 3
Can be changed: -
Unit group: -
Min
-
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: For index 1:
Only for internal Siemens troubleshooting.
p5271[0...n] Online tuning configuration controller / Ot config ctrl
Access level: 3
Can be changed: T
Unit group: -
Min
-
Description: Sets the configuration for the online tuning.
Bit field: Bit
02
06
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Note: For bit 00:
For significant differences between the motor and load moment of inertia, or for low dynamic performance of the
controller, then the P controller becomes a PD controller in the position control loop. As a consequence, the dynamic
performance of the position controller is increased.
This function should only be set when the speed pre-control (bit 3 = 1) or the torque pre-control (bit 4 = 1) is active.
For bit 01:
At low speeds, the controller gain factors are automatically reduced in order to avoid noise and oscillation at
standstill.
For bit 02:
The estimated load moment of inertia is taken into account for the speed controller gain (see p5273).
For bit 03:
Activates the speed pre-control for the basic positioner (EPOS).
For bit 04:
Activates the torque pre-control for the basic positioner (EPOS).
For bit 05:
The maximum setpoint acceleration for the basic positioner (EPOS) is determined based on the estimated moment of
inertia. This is realized by activating the bit once.
The prerequisite is that the drive pulses are inhibited, and the moment of inertia was previously determined.
For bit 06:
The speed controller gain set in p1460 is not changed when calculating the controller data.
