12. APPLICATION OF FUNCTIONS
12 - 9
Two writing methods are available.
Writing method Description
Data transmission method (Note)
MR Configurator2
Modbus-RTU
communication
Temporary writing
Write the cam control data and the cam data to the RAM of the
servo amplifier. After writing, the cam control data and the cam data
will be reflected.
The written data will be disabled if the power is turned off.
Use this when creating and adjusting the cam control data and the
cam data.
Writing
Write the cam control data and the cam data to the Flash-ROM. The
data will be enabled when the power is cycled after writing
After cycling the power, control is performed based on the written
data.
Conduct this after the cam control data and the cam data are
finalized.
Note. : Supported, : Unsupported
(2) Cam data
POINT
If the cam data is set incorrectly, the position command and speed command
may increase and may cause machine interference or [AL. 31 Overspeed].
When you have created and changed cam data, make sure to perform test
operations and make appropriate adjustments.
The following two types are available for the cam data.
Cam data type Description
Stroke ratio data type
Cam curve of one cycle is divided equally by the number of cam resolution and defined.
The cam curve will be created according to the stroke ratio data of the number of cam resolution.
Coordinate data type
Data in which cam curve of one cycle is defined with two or more points. The coordinate data is
defined as (input value, output value). The input value will be the cam axis one cycle current value,
and the output value will be the stroke value from the cam standard position.
(a) Stroke ratio data type
The following are set in the stroke ratio data type. Set the following items on the cam setting window
of MR Configurator2. When "Cam No." is set to "0", straight-line control is performed so that the
stroke ratio at the last point of the cam data becomes 100%.
Setting item Setting Setting range
Cam No.
Set a Cam No. 0: Linear cam
1 to 8: User-created cam
Setting method Set "1: Stroke ratio data type".
Cam resolution
Set the number of divisions for the cam curve of one cycle. Select from
256/512/1024/2048.
Cam data start position
Set the positions of the cam data and cam control data to the position of
when "Cam axis one cycle current value" is "0". 0 to "Cam resolution - 1"
Stroke ratio data Set the stroke ratio from the first to the last point. -100.000 to 100.000
