9-12 Examples
Example #5
Write Acceleration and Deceleration Times (C1-01 and C1-02)
to a Drive
This example will show how to write acceleration time 1 and deceleration time 1 to a drive on the
MB+ network. After writing the new acceleration and deceleration times, the new data will be
stored in Non-Volatile memory with the ‘ENTER’ command.
In this example, an input to the PLC will be used to initiate the MSTRs that will write the
acceleration and deceleration times. This input will be addressed at 10005.
This example requires multiple MSTR transactions. The following MSTR transactions will be
performed:

1 Write Accel and Decel registers 40180 40190
2 Write the ENTER command 40200 40210
The MSTR functions inserted into the ladder logic would look like:
10005 00036 00034
