Starting Operation
Section 2-2
Preparing Servo
Parameters to Be Set in
the Servo Drive
The settings for the parameter number, parameter size, and write data are set
in the Axis Operating Output Memory Area as Servo Parameters to be set in
the Servo Drive. In this operation example, the Common Parameters are set
so that the beginning word of the Axis Operating Output Memory Area for axis
1 is allocated in CIO 100. Therefore, the setting words for the Servo Parame-
ters for axis 1 are allocated as follows:
Writing Servo Parameters
to the Servo Drive
The Servo Parameter settings in CIO 117 to CIO 120 are written to the Servo
Drive. In this example, to transfer three Servo Parameters, execute the opera-
tion to write to the Servo Drive three times.
Writing the Pn50A Set Value
To write the Pn50A settings, first make the settings for transferring Servo
Parameters to the PCU's Axis Operating Output Memory Areas as shown
below.
In this example, to keep the Servo Parameters even if the Servo Drive power
is turned OFF, the Servo Parameters are saved in the non-volatile memory
(flash memory) in the Servo Drive. Servo Parameters are written from the
PCU to the non-volatile memory (flash memory) of the Servo Drive by turning
ON the SAVE SERVO PARAMETER Bit in the Axis Operating Output Memory
Area.
In this operation example, the Common Parameters are set so that the begin-
ning word of the Axis Operating Output Memory Area for axis 1 is allocated in
CIO 100. Therefore, the SAVE SERVO PARAMETER Bit for axis 1 is allocated
in CIO 10114. Turn ON this bit using the Programming Console.
While Servo Parameters are being saved to the Servo Drive, the Servo
Parameter Transferring Flag in the Axis Operating Input Memory Area turns
ON. When the Servo Parameters have finished being saved, the Servo
Parameter Transferring Flag turns OFF.
In this operation example, the Common Parameters are set so that the begin-
ning word of the Axis Operating Input Memory Area for axis 1 is allocated in
CIO 500. Therefore, the Servo Parameter Transferring Flag for axis 1 is allo-
cated in CIO 50014.
