Parameter 1-63 Slip Compensation Time Constant
Table 115: Parameter 1-63 Slip Compensation Time Constant
1-63 Slip Compensation Time Constant
Default value: Size related
Parameter type: Range, 0.05 - 5 s
Setup: All setups
Conversion index: -2
Data type: Uint16
Change during operation: True
N O T I C E
Parameter 1-63 Slip Compensation Time Constant
has no effect when
parameter 1-10 Motor Construction
=
[1] PM, nonsalient SPM
.
Enter the slip compensation reaction speed. A high value results in slow reaction, and a low value results in quick reaction. If low-
frequency resonance problems arise, use a longer time setting.
Parameter 1-64 Resonance Damping
Table 116: Parameter 1-64 Resonance Damping
1-64 Resonance Damping
Default value: Size related
Parameter type: Range, 0 - 1000%
Setup: All setups
Conversion index: 0
Data type: Uint16
Change during operation: True
N O T I C E
Parameter 1-64 Resonance Damping
has no effect when
parameter 1-10 Motor Construction
=
[1] PM, nonsalient SPM
.
Enter the resonance damping value. Set
parameter 1-64 Resonance Damping
and
parameter 1-65 Resonance Damping Time Constant
to help eliminate high-frequency resonance problems. To reduce resonance oscillation, increase the value of
parameter 1-64 Reso-
nance Damping
.
Parameter 1-65 Resonance Damping Time
Table 117: Parameter 1-65 Resonance Damping Time Constant
1-65 Resonance Damping Time Constant
Default value: 5 ms
Parameter type: Range, 1 - 50 ms
Setup: All setups
Conversion index: -3
Data type: Uint8
Change during operation: True
N O T I C E
Parameter 1-65 Resonance Damping Time Constant
has no effect when
parameter 1-10 Motor Construction
=
[1] PM, non-salient
SPM
.
Set
parameter 1-64 Resonance Damping
and
parameter 1-65 Resonance Damping Time Constant
to help eliminate high-frequency res-
onance problems. Enter the time constant that provides the best dampening.
