9.4 Setting and accessing communication parameters
Refer to Chapter 8 for the descriptions of the parameters that you can write or read through the
communication interface.
The ASDA-A3 servo drive parameters are divided into nine groups: Group 0 (Monitoring
parameters), Group 1 (Basic parameters), Group 2 (Extension parameters), Group 3
(Communication parameters), Group 4 (Diagnosis parameters), Group 5 (Motion control
parameters), Group 6 and Group 7 (PR parameters), and Group M (Motor parameters).
Setting parameters through communication:
You can set parameters through communication:
Group 0, except (P0.000 - P0.001), (P0.008 - P0.013), and (P0.046).
Group 1
Group 2
Group 3
Group 4, except (P4.000 - P4.004) and (P4.008 - P4.009).
Group 5, except (P5.010), (P5.016), and (P5.076).
Group 6
Group 7
Group M
Note the following additional details:
P3.001: when changing to a new communication speed, the next data is written in the new
transmission speed after the new speed is set.
P3.002: when changing to a new communication protocol, the next data is written with the new
communication protocol after the new protocol is set.
P4.005: JOG control parameters. Refer to Chapter 8 for detailed descriptions.
P4.006: force digital output (DO) contact control. Use this parameter to test the DO contact.
Set P4.006 to 1, 2, 4, 8, 16, and 32 to test DO1, DO2, DO3, DO4, DO5, and DO6,
respectively. Then, set P4.006 to 0 to complete the test.
P4.010: calibration functions. First set P2.008 to 20 (14H in hexadecimal format) to enable this
function.
P4.011 - P4.021: these parameters are for adjusting the hardware offset. The parameters were
adjusted before delivery, so changing these parameters is not recommended.
If you need to modify these parameters, first set P2.008 to 22 (16H in
hexadecimal format).
Accessing parameters through communication:
You can read the values from parameters through communication: Group 0 - Group 7, and
Group M.
