3-8 Operation

Index Division Ratio Selection

Switch 3 and Switch 4 are used to create 4 patterns based on their
ON/OFF combinations. The patterns determine the pulse ranges, the
pulses per revolution, and the counts per revolution.

Maximum Effective Motor Speed

The Maximum Effective Motor Speed is dependent on the combined
values for Switch 3 and Switch 4. Only one of the switches numbered
5 through 10 should be in the ON position. The default setting has
Switch 5 in the ON position with switches 6 through 10 in their OFF
positions.

TIP

Having more than one switch, in series 5 through 10,
set to the ON position results in an undefined
maximum RPM speed. No switches, in series 5
through 10, set to the ON position results in an
output speed of zero. In either case, no damage is
done to the ESRS.
