2.2 List of parameters
Description: Sets the limit value for slip compensation in [%] referred to r0330 (motor rated slip).
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Description: Displays the actual compensated slip [%] referred to r0330 (rated motor slip).
Dependency: p1335 > 0 %: Slip compensation active.
Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Refer to: p1335
Description: Sets the gain for resonance damping for U/f control.
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Refer to: p1300, p1339, p1349
Note: The resonance damping function dampens active current oscillations that frequency occur under no-load conditions.
The resonance damping is active in a range from approximately 6 % of the rated motor frequency (p0310). The
shutoff frequency is determined by p1349.
For the open-loop control modes p1300 = 5 and 6 (textile sectors), the resonance damping is internally disabled in
order that the output frequency can be precisely set.
Description: Sets the filter time constant for resonance damping for U/f control.
Dependency: Not visible with application class: "Dynamic Drive Control" (DDC, p0096 = 2)
Refer to: p1300, p1338, p1349
