The Speed Range is designated to be "Low Speed" when
the switch is in the "L" position and designated to be "High
Speed" when the switch is in the "H" position.
The starting speed (or base speed) is fixed at 50pps in the
low speed range, and 300pps in the high speed range and
cannot be changed.
Table 2: Setting the Running Speed
Pins 1 through 16 are used for setting the index data (number of
steps, 0000 to 9999). They are arranged in binary coded decimal
(BCD) format A pin is designated to be "ON" when there is
continuity between it and ground (GND= pin "31, see schematic on
p.16). This connection to the ground pin can be made through a
switch, a transistor, or it can be made directly (hard wired). This
makes the U1215GA ideally suited for use with programmable
controllers. Ta b l e 5: Connecting Terminals
* When rate 3 is selected, there is no acceleration or decel-
eration. Therefore, the motor will start at the selected
running speed. If the running speed is greater than the
no load self-starting frequency (marked as fs on the
torque-speed curves on pages 36 and 37), the motor
will not start.
