9. SPECIAL ADJUSTMENT FUNCTIONS

(2)Parameters

The operation of adaptive vibration suppression control selection (parameter No.60).

Parameter No. 63

0 0

Adaptive vibration suppression control selection Choosing "valid" or "held" in adaptive vibration suppression control selection makes the machine resonance suppression filter 1 (parameter No. 61) invalid.

0:Invalid

1:Valid

Machine resonance frequency is always detected to generate the filter in response to resonance, suppressing machine vibration.

2:Held

Filter characteristics generated so far is held, and detection of machine resonance is stopped.

Adaptive vibration suppression control sensitivity selection

Set the sensitivity of detecting machine resonance.

0:Normal

1:Large sensitivity

POINT

Adaptive vibration suppression control is factory-set to be invalid (parameter No. 63: 0000).

The filter characteristics generated are saved in the EEP-ROM every 60 minutes since power-on. At next power-on, vibration suppression control is performed with this data saved in the EEP-ROM being used as an initial value.

Setting the adaptive vibration suppression control sensitivity can change the sensitivity of detecting machine resonance. Setting of "large sensitivity" detects smaller machine resonance and generates a filter to suppress machine vibration. However, since a phase delay will also increase, the response of the servo system may not increase.

9.4 Low-pass filter

(1)Function

When a ballscrew or the like is used, resonance of high frequency may occur as the response of the servo system is increased. To prevent this, the low-pass filter is factory-set to be valid for a torque command. The filter frequency of this low-pass filter is automatically adjusted to the value in the following expression:

Filter frequency(Hz)

 

 

 

Speed control gain 2 setting 10

 

 

 

 

2

(1 Ratio of load inertia moment to servo motor inertia moment setting 0.1)

 

 

 

 

 

(2)Parameter

Set the operation of the low-pass filter (parameter No. 60.)

Parameter No. 63

0

Low-pass filter selection

0:Valid (automatic adjustment) initial value

1:Invalid

POINT

In a mechanical system where rigidity is extremely high and resonance is difficult to occur, setting the low-pass filter to be "invalid" may increase the servo system response to shorten the settling time.
