The Full Scale Speed is the highest running speed desired.
For this application, the maximum motor speed is 1800
RPM.
The Full Scale Frequency is determined by the maximum
motor RPM, the encoder resolution, and the motor to
encoder gearing (if any). In this example, it is
1800 rpm.;. 60 sec/minute x 300 ppr
=
9 kHz
The Adjust input is a panel mounted quadrature encoder
"pot".
The "pot" Adjust Rate (resolution) is 10 RPM for each
quadrature edge (X4 logic). With a 5 ppr encoder, one turn
changes the Speed Setpoint by (5 ppr x 4 x 10 RPM
= )
200
RPM.

MOTOR
The Full Scale Speed is the highest running speed desired.
For this application, the maximum motor speed is 7200
RPM.
The Full Scale Frequency is determined by the maximum
motor RPM, the encoder resolution, and the motor to
encoder gearing (if any). In this example, it is
7200 rpm.;. 60 sec/minute x 100 ppr
=
12 kHz
The Adjust input is a pair of remote contacts; one each for
Increase and Decrease Speed functions.
The "mop" Adjust Rate is 99 RPM/sec while either switch is
closed. Note that the Run/Stop input is jumpered; starting
and stopping can be performed with the Run/Pgm key
(provided the PGM DIS switch is Off).
