3.3 Setting of Position Data
75
12) Incremental········· Set to 1 for pitch feed (relative movement = incremental feed).
The value set for the position in 1) indicates the pitch feed distance.
With the value set to 0, positioning is defined to the position in 1) based
on the absolute coordinate system.
Caution: In the pitch feed, do not perform a command with a pitch smaller than the
minimum encoder resolution (lead/encoder pulse number) or that less than
positioning accuracy repeatability.
There would be no deviation to occur even with the command because it is an
operation command to the same position as the positioning complete condition,
but the positioning control cannot be performed properly.
When solenoid valve mode 2 is selected, set this to 0. Setting this to 1 causes the
position data error to occur.
13) Gain set ·············· Six parameters required for servo gain adjustment are collected to be a
single set. 4 types of settings are able to be registered and the servo
gains can be switched over for each positioning operation. By utilizing
Smart Tuning Function
(Note)
in the PC software, the setting close to the
optimum can be obtained.
(Note) Refer to Chapter 9 Appendix Connectable Actuators for the
applicable models.
It may require the setting of the gain set dedicated for the
home-return operation in the case this function is used to have
the high-speed setting or the setting to apply a transported
weight more than the ratings.
For how to set up and the caution items, refer to the instruction
manual for RC PC Software.
