[Operation example]
The following operation assumes that the speed-position switching signal is input at the position of the
feed current value of 90.00000 [degree] during execution of "[Da.2] Control method" "Forward run:
speed/position" at "[Pr.1] Unit setting" of "2: degree" and "[Pr.21] Feed current value during speed
control" setting of "1: Update feed current value".
(The value set in "[Da.6] Positioning address/movement amount" is 270.00000 [degree])
