Analog Speed Setpoint Inputs
Analog speed setpoint inputs are available for
rotators 1 through 6 at breakout terminals J2-A1
through J2-A6. Using dip switch 6 of SW1 on
the Control Card, these inputs can all be set so a
0-10VDC or 4-20mA input signal gives 0-100,000
rpm rotator speed. See "Dip Switch Settings" later
in this section.

For 4-20mA input signals, the following equation
can be used to determine the mA input signal
corresponding to a given speed:
Table 3 shows 0-10VDC and 4-20mADC input
signals for speeds from 0 to 100,000 rpm in steps
of 5,000 rpm.
