17. APPLICATION OF FUNCTIONS
This chapter explains the application of using servo amplifier functions.
17.1 Scale measurement function
The function transmits position information of a scale measurement encoder to the controller by connecting
the scale measurement encoder in semi closed loop control.
POINT
The scale measurement function is available with servo amplifiers with software
version B0 or later.
When a linear encoder is used as a scale measurement encoder with this servo
amplifier, the "Linear Encoder Instruction Manual" is necessary.
For the controller settings to use the scale measurement function, refer to the
MR-J4-_TM_ Servo Amplifier Instruction Manual for each communication
method.
17.1.1 Functions and configuration
(1) Function block diagram
The following shows a block diagram of the scale measurement function. The control will be performed
in units of encoders of the servo motor for the scale measurement function.
