ASDA-A2 Chapter 9 Communications
9-18 Revision February, 2017
9.4 Write-in and Read-out Communication Parameters
Please refer to Chapter 8, Parameters for all parameter details. And the descriptions of parameters
which can be wrote or read through communication are as follows.
Parameters are divided into 8 groups, Group 0: Monitor Parameters, Group 1: Basic Parameters,
Group 2: Extension Parameters, Group 3: Communication Parameters, Group 4: Diagnosis
Parameters, Group 5: Motion Setting, Group 6 and Group 7: PR Definition.
Write parameters via communication:
Parameters which can be written through communication include:
Group 0, except (P0-00~P0-01), (P0-08~P0-13) and (P0-46) Group 1 (P1-00~P1-76)
Group 2 (P2-00~P2-67)
Group 3 (P3-00~P3-11)
Group 4, except (P4-00~P4-04) and (P4-08~P4-09)
Group 5 (P5-00~P5-99), except P5-10, P5-16 and P5-76
Group 6 (P6-00~P6-99)
Group 7 (P7-00~P7-27)
Please note that:
(P3-01) When change to a new communication speed, the next data will be written in a new
transmission speed after setting the new value.
(P3-02) When change to the new communication protocol, the next data will be written with the
new communication protocol after setting the new value.
(P4-05) JOG controls parameters of the servo. Please refer to Chapter 8, Parameters for the
description.
(P4-06) Force to control output contact. This parameter is for DO (Digital Output) testing. Users
can write 1, 2, 4, 8 and 16 to test DO1, DO2, DO3, DO4 and DO5 respectively. Please
write 0 after the test so as to inform the servo drive that the test has been completed.
(P4-10) Adjustment function selection. Write 20 (= 14H in hexadecimal format) in parameter P2-
08 first to enable the adjustment so as to change the value of P4-10.
(P4-11 ~ P4-21) This parameter is Offset Adjustment. Do not change the setting unless it is
necessary. If it is necessary, please write 22 (= 16H, in hexadecimal format) in
parameter P2-08 first to enable the function so as to change the value of (P4-11 ~
P4-21)
Read parameters through communication:
Parameters can be read through communication include:
Group 0 (P0-00~P0-46) Group 4 (P4-00~P4-23)
Group 1 (P1-00~P1-76) Group 5 (P5-00~P5-99)
Group 2 (P2-00~P2-67) Group 6 (P6-00~P6-99)
Group 3 (P3-00~P3-11) Group 7 (P7-00~P7-27)
