(Explanation) The current speed data is “0000H.”
In other words, the current speed is “0” in this example.
The current speed is indicated in units of 1.0 mm/sec.
The current speed is set as a multiple of 1.0 mm/sec or 0.1 mm/sec.
The unit is changed on the special parameter setting screen of the ROBONET gateway parameter
creation tool. (The unit change function is supported by tools of version 1.0.4.0 and later.)
