Appendix

ە Speed Loop Integral Time Constant (Parameter List 1)

Driver guard parameter No. Unit Input range Default (reference)

39 - 1~1000 30

This parameter determines the level of response with respect to a speed control loop.

Increasing the setting results in lower response to the speed command and decreases the reactive force upon

load change. Compliance with the position command drops and the positioning time increases as a result.

However, decreasing the setting too much increases the tendency of the actuator to overshoot or oscillate,

resulting in increased mechanical vibration.

ە Current Loop Control Band Number

Driver guard parameter No. Unit Input range Default (reference)

40 - 0 ~4 4

This parameter sets the control band for the PI current control system.

Normally the default setting need not be changed.

If this parameter is changed inadvertently, stability of the control system may be affected and a very dangerous

situation could occur.

This parameter is useful in certain situations. For example, changing the parameter will suppress resonance

noise should it generate. If you wish to change this parameter, consult IAI.

ە Torque Filter Time Constant (Parameter List 1)

Driver guard parameter No. Unit Input range Default (reference)

42 - 1~2500 0

This parameter determines the filter time constant applicable to the torque command.

If the mechanical resonance frequency is equal to or lower than the servo loop response frequency, the motor

will vibrate.

This mechanical resonance can be suppressed by increasing the setting of this parameter.

It should be noted, however, that increasing the setting too much may affect the stability of the control system.

Setting is low (overshoot)

Setting is high
