Example 2:
Setting the Accel Time 1 Parameter C1-01 Value by Explicit Messaging
To set parameter C1-01 (Modbus register 0200 Hex) Acceleration Time 1 to 3.5 seconds, first convert the Modbus register
number to DeviceNet Instance and Attribute.
Then, send an explicit message with Service Code 10 Hex (Set Attribute Single) to Class 64/Instance 2/Attribute 00 Hex, with
the data field as 23 Hex (35). The data field does not recognize decimal places, so the data must be written as a whole number.
Also, in reading and setting to parameters C1-01 to C1-09 Accel/Decel Time 1 to 4, be sure to check the setting of parameter
C1-10 Accel/Decel Time Setting Unit. For instance, in the above example, if C1-10 is set to value of 1 (0.01 – two decimal
places) instead of the default value (0.1 - one decimal place), the data field to set acceleration time to 3.50 seconds would be
15E Hex (350). Refer to the drive User Manual for further drive parameter descriptions.
