Definition of Angle and its Range
●
Definition of “0 degrees” and operational range
“0 degrees” and dire/-) of RS204MD are defined as fig. 2.7.
Operational range (for Goal Position) is 0
±
150deg, and Detectable range (for Present Position) is 0
±
160 deg.
fig. 2.7 Definition of Angle
●
Dead Zone(undetectable range)
The range of more than +160 degrees to less than -160 degrees in fig. 2.7 is undetectable area (“Dead
Zone”) of internal angle sensor.
When in this range, ”Present Position” (p.39

) will be
“555.5” and “Torque Enable”(p.38) will be “00H” (Torque-OFF).
To turn on the torque again, please move output-axis to Operational Range then send Torque-ON
command.
You can rotate the output-axis by hand beyond the Dead Zone since there is no mechanical limit
(stopper) on the 160 degrees and -160degrees, but please keep in mind that passing the dead zone
frequently, such as continuously rotating the output shaft, will damage the angle sensor and may be
shorten its life.
