If the motor is wired according to the motor wiring section,
Motor speed and the function of the RUN input can be determined from the

SPD (speed) input selects speed range. LO SPEED and HI SPEED pots adjust the 2
speed ranges.
EXT SPD=ON speed adjusted by LO SPEED trimpot - range up to 5 rev/sec
EXT SPD=OFF speed adjusted by HI SPEED trimpot - range up to 25 rev/sec
If switch #2 is toward the words EXT SPEED, then the high speed is proportional to
the voltage applied to the WPR terminal, and is trimmed by the HI SPEED pot. You
can connect an external 1K - 5K pot to the WPR, CW and CCW terminals, or you can
apply a 0 to 5 volt analog signal to the WPR terminal (ground your analog signal to the
CCW pin.) The high speed range is 0 - 25 rev/sec (0 - 1500 rpm.) You can reduce the
range by turning down the HI SPEED pot.
When switch #2 is away from the EXT SPEED label, the high speed is set by the HI
SPEED pot and the WPR input does nothing.
Never apply more than 5 volts DC or less than 0 volts to the WPR pin.
In both operating modes, the accel/decel rate is set by the ACCEL pot. The
range is 1 to 250 rev/sec/sec.

Modes of Operation
Note: We refer to an input as being ON when current is flowing
through the input. A signal is OFF when no current is flowing. An
input is OFF when COM and the input terminal are at the same voltage,
or when the input is left unconnected (open).
The 3540 MO features two modes of operation.
Joystick mode
Joystick mode is set by moving switch #1 toward the word "Joystick". Switch #2
(EXT SPEED) has no effect in Joystick mode.
Joystick mode - speed and direction are determined by the voltage applied to the WPR
(wiper) terminal. 2.5 volts is "stopped" (no speed). Increasing the WPR voltage
toward 5 volts results in forward motion: speed increases with voltage. Decreasing
the WPR voltage from 2.5 toward 0 results in reverse motion, with speed increasing
as voltage decreases. The SPD (speed) input selects speed range. LO SPEED and HI
SPEED pots adjust the 2 speed ranges.
EXT SPD=ON speed adjusted by LO SPEED trimpot - range up to 5 rev/sec
EXT SPD=OFF speed adjusted by HI SPEED trimpot - range up to 25 rev/sec
In joystick mode, limit switches can be connected to the 3540 MO.

Speed Control from a 0 to 5 Volt Analog Signal
In oscillator mode, the 3540MO can rotate the motor a speed proportional to an
analog voltage. The voltage must be applied to the WPR terminal. The direction of
rotation will be controlled by the digital DIR input and the motor can be stopped
either by setting the analog input voltage to 0 or by turning the digital RUN signal
off.
To use the 3540 MO in this mode, set switch #1 away from the JOYSTICK label,
and set switch #2 toward the EXT SPEED label.
DRAWING...........
The HI SPEED pot sets the maximum speed (the motor speed when the analog
signal is at 5 volt DC). The range is 0 - 25 rev/sec.
