Saturation Behavior - Parker Compax3S025V2 Operating Instructions Manual

Parker EME
Note:
Depth filter 1 (O2150.3) / depth filter 2 (O2150.6)
With this the size of the attenuation of the filter must be at the position of the center
frequency. One stands here for complete attenuation (-∞ dB) and zero for no
attenuation.

Saturation behavior

In this chapter you can read about:
Current jerk response ......................................................................................................................171
Current jerk response with the activated saturation characteristic line............................................171
Saturation can be stated with the aid of current jerk responses at different current
height.
Current jerk response
Current jerk response of a motor to 2 different currents (1Arms / 2Arms)
2) (1Aeff)
1)
1) Actual current
2) Setpoint current
In the above figure we can see from the settling response that the drive shows a
distinctive tendency to oscillate at doubled current. The saturation characteristic
line, which is used to linearly reduce the P-term of the current loop depending on
the current, helps against such a saturation behavior.
If you respect the saturation for the above example with the aid of the saturation
characteristic line, the tendency to oscillate of the current loop can again be
activated.

The paramterization of the characteristic line is made in the MotorManager.
In order to accept the changes in the MotorManager in the project, the
entire configuration must be confirmed.
In order to make the changes from the MotorManager effective in the device, the
configuration download must be executed.
