2.2 List of parameters
Note:
The purpose of slip compensation is to maintain a constant motor speed regardless of the applied load. The fact that
the motor speed decreases with increasing load is a typical characteristic of induction motors.
For synchronous motors, this effect does not occur and the parameter has no effect in this case.
For the open-loop control modes p1300 = 5 and 6 (textile sector), the slip compensation is internally disabled in order
to be able to precisely set the output frequency.
If p1335 is changed during commissioning (p0010 > 0), then it is possible that the old value will no longer be able to
be set. The reason for this is that the dynamic limits of p1335 have been changed by a parameter that was set when
the drive was commissioned (e.g. p0300).
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
