The damping control function suppresses vibration of low-rigidity mechanisms or devices whose tips
tend to vibrate.
Two damping filters are provided to enable switching the damping frequency automatically according to
the movement direction and also via an external signal. In addition, the settings can be made easily by
setting the damping frequency and filter values.
EtherCAT is an open high-speed industrial network system that conforms to Ethernet (IEEE 802.3).
Each node achieves a short cycle time by transmitting Ethernet frames at high speed. A mechanism
that allows sharing clock information enables high-precision synchronization control with low
communications jitter.

G5-series AC Servo Drives With Built-in EtherCAT Communications, Linear Motor Type use the object
dictionary for CAN application protocol over EtherCAT (CoE) as a base for communications.
An object is a special data structure inside a device that consists of data, parameters, and methods.
An object dictionary is a data structure that describes the data type objects, communications objects,
and application objects.
All objects are assigned four-digit hexadecimal numbers in the areas shown in the following table.
*1
G5-series Servo Drive parameters (Pn
) are allocated to objects 3000 to 3999 hex. Index 3
hex
correspond to G5-series Servo Drive parameters Pn
. For example, object 3504 hex is the same as
parameter Pn504.
Pn
uses decimal numbers but object 3
is a hexadecimal number.
For details on servo parameters, refer to Section 9 Servo Parameter Objects.
