PrNo. Parameter

Value

Unit Function

• This amplifier provides 2(two) sets (1st. and

2nd.) of gain and time constant for position loop,

velocity loop, velocity detection filter and torque

command filter.

• The functions and meanings of these 2nd gains

or time constants are the same as those of the

1st ones mentioned in the previous page.

• For switching between the 1st and 2nd gains or

constants, see Adjustment.

* If Pr20 (inertia ratio) has been set correctly, the

unit of the values of Pr11 and Pr19 is Hz.

•

You can set-up the frequency of the resonance suppression notch

filter.

•

You can set-up frequency 10% lower than the resonance frequency of the

machine system which you can obtain by the frequency characteristics

analysis program contained in PANATERM ®.

•

This notch filter function will be disabled by setting this

parameter at1500.

•

You can set-up the width (five options) of the resonance

suppression notch filter in 5 steps. The higher the setting

is, the wider the width you can obtain.

•

In normal cases, the default value should be used.

•

You can set-up the time constant (eight options) of the primary delay filter

inserted in the Disturbance torque observer.

Value of Pr1F

Disturbance torque

observer disabled.

* 1Note that the running noise of the motor becomes larger, with a smaller value of Pr1F(better suppres-

sion of the Disturbance torque). It is recommended that you start from the larger value of Pr1F to see

the actual response and decrease the value.

•

For the calculation of Disturbance torque in the observer, the inertia ratio (Pr20) is necessary. If the

load inertia is known, calculate the inertia ratio and set the value of Pr20 to the inertia ratio calcu-

lated. If the load inertia is unknown, perform the auto gain tuning so that you can automatically enter

the value of Pr20.
