3.7 Address Configuration
A3-60
ME0384-4A
[Full servo control method]
Holding current can be reduced by using servo control with stepper motors.
While the degree of reduction varies depending on the actuator model and load conditions, the
holding current drops to about 1/2 to 1/4.
No position deviation will occur as the system maintains the servo ON status. The actual holding
current can be checked using the current monitor screen within PC software.
(13) Vibration damping No.
Suppresses vibration (resonance) of the load attached to the actuator.
Handles 3 types of vibrations.
For each vibration, 4 parameters are established and treated as 1 set.
The position table configures parameter sets that correspond to the position No. that needs
vibration damping.
For details, refer to "6.2 Various Functions/Vibration damping control function (page B6-65)".

This function is limited to servo motor specification actuators.
For stepper motor specification or DC brush-less motor specification actuators, this should be
set to 0.
Caution
● The vibration frequency that can be suppressed (targeted natural frequency) is 0.5Hz to
30Hz.
● Vibration of the load to which vibration is induced due to the actuator connected to this
controller is applicable. Other vibrations cannot be damped.
● Vibration in the same direction as the direction of movement of the actuator is
applicable. Other vibration directions cannot be damped.
● Home return and push-motion operation are not applicable.
● If the vibration frequency setting is low, the tact time may increase. At less than about 6
Hz, the positioning convergence time will be over 150ms.
