9.4 Setting and accessing communication parameters
Please 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 eight 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) and Group 6 and Group 7 (PR 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
Please 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. Please refer to Chapter 8 for detailed descriptions.
P4.006: Force Digital Output (DO) contact control. You can 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 it is necessary,
set P2.008 to 22 (16H in hexadecimal format) first.
Accessing parameters through communication:
You can read the values from parameters through communication: Group 0 ~ Group 7.
