Description: Displays the checksum for tracking changes for Safety Integrated.
These are additional checksums that are created to track changes (fingerprint for the "safety logbook" functionality) to
safety parameters (that are relevant for checksums).
Index: [0] = SI checksum to track functional changes
[1] = SI checksum to track hardware-specific changes
Dependency: Refer to: p9601, p9729, p9799

Description: Displays the time stamps for the checksums for tracking changes for Safety Integrated.
The time stamps for the checksums for tracking changes (fingerprint for the "safety logbook" functionality) made to
safety parameters are saved in parameters p9781[0] and p9781[1].
Index: [0] = SI time stamp for checksum to track functional changes
[1] = SI time stamp for checksum to track hardware-specific changes
Dependency: Refer to: p9601, p9729, p9799

Description: Sets the additional field-generating current for synchronous motors with sensorless actual value sensing.
The set value is referred to p0305.
This parameter ensures a "base load" for the motor.
The value must fulfill the following condition:
|p0305 x p9783| >= p9588 x 1.2
Dependency: Refer to: p9588
Notice: Reducing this percentage value can adversely affect actual value sensing with synchronous motors.
If the value is increased, this results in an increased motor power loss.
Note: This parameter is only effective for encoderless actual value sensing (p9506/p9306 = 1, 3).
For p9783 = maximum value, current injection is deactivated.
Current injection is not effective in the U/f control mode.
