3.3 Setting of Position Data
76
Caution:
y
No retaining torque is provided in automatic servo OFF. Pay sufficient
attention to the setting because the actuator may be moved by external force
applied to it.
y
Do not use the automatic servo OFF if the next moving command is relative
distance specification (pitch feed). Failure to follow it may cause position shift
to occur.
y
Do not use the automatic servo OFF in pressing. If used, the pressing force is
lost.
y
Automatic Servo OFF would not function in the operation with teaching mode
of PC software.
15) Vibration suppress No.····· Suppresses vibration (sympathetic vibration) of the load
installed on the actuator.
It possesses a capacity to deal with 3 types of vibration.
There are 4 parameters corresponds to 1 type of vibration and
they are compiled in 1 set.
Set the parameter set corresponds to the position number
necessary for the vibration control in the position table.
[Refer to Chapter 5 Vibration Suppress Control Function.

Caution: (1) The vibration frequency that can be controlled (applicable specific
frequency) is from 0.5 to 30Hz.
(2) The vibration control is applicable only for the vibration generated by the
load of the actuator connected to this controller.
Other vibrations cannot be controlled.
(3) The vibration control is applicable only for the vibration in the direction of the
actuator operation. Vibration in other directions cannot be controlled.
(4) The vibration control is not applicable for home-return and pressing
operations.
(5) If the vibration frequency setting is low, the takt time may become long. The
value below approximately 6Hz makes the positioning finishing to take more
than 150ms.
