Typical wiring for Oscillator Mode using external speed Control pot
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.
Wiring diagrams and a plot of speed vs voltage are shown below.

Modes of Operation
Note: We refer to an input as being ON when current is owing
through the input. A signal is OFF when no current is owing. 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.
Refer to the full manual - available from the website for connection details.
Oscillator mode
Oscillator mode is selected by moving switch #1 away from the word Joystick.
Thespeed can be controlled by on-board potentiometers and/or
by an external analog voltage. RUN input starts and stops the motor. DIR input
controls direction of rotation. SPD input selects the speed range.
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
following table.
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.

Choosing a Power Supply
To nd out how to choose a power supply refer to the tech notes on our website.
Mounting the Drive
To operate the drive continuously at maximumpower you must properly mount it on
a heat sinking surface with a thermal constant of no more than 4°C/watt. Often, the
metal enclosure of your system will make an effective heat sink.

Idle Current Reduction
Your drive is equipped with a feature that automatically reduces the motor
current by 50% anytime the motor is not moving. . Idle current reduction is
enabled by sliding switch #4 toward the 50% IDLE label,as shown in the
sketch below. Sliding the switch away from the 50% IDLE label disables the
reduction feature

Microstepping
The 3540 MO divides each full step into 64 microsteps, providing 12,800 steps
per revolution for precise positioning and smooth motion.
Connecting the Motor
STEP motors have 4, 6 or 8 leads , these are
wired to 4 connections on the drive in various
combinations.
Motors will perform differently according the
way it is connected, to nd out more about the
differnet way of connecting your motor , see the
technotes or FAQs on our website.
Warning: When connecting
the motor to the driver, be
sure that the motor power
supply is off. Secure any
unused motor leads so that
they can’t short to anything.
Never disconnect the motor
while the drive. Never con-
nect motor leads to ground
or to a power supply!

Tach Output
The Tach Out signal is provided for measuring the motor speed. It generates
100 pulses per revolution, so if you connect a frequency counter, the speed
reads out in revs/second with two decimal places. The schematic diagram of
the Tach Out optoisolation circuit is shown below.
Do not connect the Tach output to more than 24VDC.
The current into the Tach+ terminal must not exceed 20 mA.

Connecting Digital Inputs and Limit Switches
You must supply 5-24 volts DC to supply current to the LEDs on the input side
of the opto-isolators.Your controlling logic must be capable of sinking or sourc-
ing at least 3 mA at 5 volts and 10 mA at 24 volts to control each drive input.
Sinking Circuits (NPN) - If your output devices prefer to sink current, then
connect the COM terminal to your positive power supply. If you are using a
TTL circuit to drive the 3540 MO, connect the COM terminal to your 5 volt bus.
No ground connection is needed. If you are using a PLC or proximity sensor,
you’ll need a power supply.
Sourcing circuits (PNP) - If your output devices can only source current (some
PLC outputs are this way), connect the COM terminal to the ground of the DC
power supply that powers your output circuits Note: We refer to an input as
being ON when current is owing through the input. A signal is OFF when no
current is owing. An input is OFF when COM and the input terminal are at the
same voltage, or when the input is left unconnected (open).
The ENABLE input allows the user to turn off the current to the motor by
setting this signal on. The logic circuitry continues to operate, so the drive
“remembers” the step position even when the ampliers are disabled. If you
have no need to disable the ampliers, you don’t need to connect anything to
the ENABLE input.
