OVERVIEW
ECM3000 control motors are designed to control various types of
industrial equipment.
There are two types of strokes: a 90° stroke for burner control and
a 160° stroke for valve control using hot and cold water, steam,
etc. There are three types of control signal inputs: relay contact,
4–20mADC, and potentiometer (nominal 135Ω resistance input).
24, 100, and 200VAC models are available. Flexible 85–264VAC
powered models are also available for 4–20mADC signal input
models. The included bracket can be used for replacement of an
older Azbil Corporation motor with this one.

Handling Precautions
• Use high-speed motor models at a duty ratio (operating ratio) of 40% or less.
• Do not connect the ECM3000F to a mechanical balancing relay such as the R9107A or R927C. Doing so may apply excessive voltage to
the potentiometer, resulting in device failure.
• Be sure to connect non-voltage contacts to terminals S, CONT, CW, and CCW of an ECM3000 model with forced open/close function.
In the case of the M744 and M7284, 24VAC may be applied to the S, CONT, CW, and CCW terminals.
If the ECM3000 is replaced with a forced open/close function model, do not apply 24VAC to any terminal. Doing so will damage the
circuit.
• For the ECM3000F and ECM3000D, leakage current from the snubber circuit protecting the motor drive element (relay or SSR) must
be within the following.
• 100VAC: 0.8mA (RMS) max.
• 200VAC: 0.4mA (RMS) max.

MOUNTING
Installation location
To install the ECM 3000, use the supplied bolt or equivalent (M6
size, with spring washer and flat washer). Use a nut (not supplied)
if necessary.
Bolt tightening torque: 4.1 to 5.2 N·m
Do not install the device in locations prohibited in the SAFETY
PRECAUTIONS section. For outdoor use, use a protective cover
or the like.
Handling Precautions
• Prevent foreign matter or moisture from entering the
device from the output shaft.
• When the motor is used with a control valve in an appli-
cation such as fluid control, if the control valve is located
higher than the motor, water drops may enter the motor
by running along the valve.
Mounting orientation
l90° stroke model
This model can be mounted with any desired orientation.
However, take measures to prevent water and foreign matter
from entering the output shaft.
l160° stroke model
This device can be mounted with the output shaft horizontal or
facing downwards. To prevent water drops from entering the
device, do not mount with the output shaft facing upward.
Incorrect Incorrect Incorrect
To ensure splash-proofing
Close the cover securely so that the packing and cable are not
pinched. Make the knockout hole watertight after wiring.
• Use a waterproof connector for the cables running from the
motor. Recommended waterproof connector: refer to the
sealing item of specifications
• If a conduit is used, use a waterproof precut tube or the like
to ensure waterproofing.
WIRING
Symbols used on the device:
Symbol Meaning
AC power supply
DC signal
Functional ground terminal (not a protevtive ground terminal)
CAUTION
Make sure that the frame ground terminal is properly
grounded (100Ω max.) using at least 2mm2wire and
M4 crimp terminals with insulating sleeves.
During wiring, open a knockout hole (22mm dia.) on either side,
and pull out the cables from the hole. For wiring to the terminals,
follow the terminal label indicated on the terminal block, and be sure
to use M3.5 crimp terminals with insulating sleeves.
Handling Precautions
• To open a knockout hole, using a flat-head screwdriver, set
its tip on the outer edge of the knockout plug, and lightly
tap the screwdriver all the way around this edge until the
knockout is removed.
• Do not allow any fragments to enter the actuator when the
knockout hole is opened.
• Do not use unused terminals on the device as relay
terminals.
• Be sure to attach the cover after wiring is complete.
• Do not run the signal wires in the same conduit as power lines.
• Keep power cables at least 50cm away from signal cables.
• If the power and signal cables must run together in the
same conduit, use JCS4364-compliant instrument cable
for signals.
• Use the appropriate supply voltage according to the
model No.
• Be sure to install a circuit breaker (8A max) for the power
source.
• During motor operation, in order to stop hunting (which
causes the controller’s internal relay to turn ON and OFF
excessively), change the parameters of the controller.
For example, set the derivative time (D) to 0 seconds, set
a wider dead band, etc.
If the internal relay operates excessively, the life of the
motor or the host controller relay will be shortened.

Note
• The 4–20mA input circuit is isolated from the power circuit
inside the device.
Handling Precautions
• During motor operation, in order to stop hunting (which
causes the controller’s internal relay to turn ON and OFF
excessively), change the parameters of the controller. For
example, set the derivative time (D) to 0 seconds, set a
wider dead band, etc.
If the internal relay operates excessively, the life of the
motor or the host controller relay will be shortened.
If frequent operation cannot be avoided, install an auxiliary
relay between the motor and controller.
• The feedback potentiometer of the ECM3000F is a com-
bination resistor consisting of two different resistors con-
nected in parallel.
Accordingly, the angle of rotation of the ECM3000F is pro-
portional not to the resistance of the feedback potentiom-
eter but to the voltage ratio between the potentiometer
terminals (T–G voltage or Y–G voltage).
The resistance of the feedback potentiometer cannot be
used to measure the angle of the motor rotation.

Handling Precautions
• Before shipment, terminals CONT and S are connected.
Disconnect these terminals if operation with the valve
forced fully open (or closed) is desired.
• Only one of terminals CCW, CW, and CONT can be con-
nected to terminal S. Multiple terminals cannot be con-
nected to terminal S.
• Be sure to connect non-voltage contacts to terminal S,
CONT, CW, or CCW of an ECM3000 model with a forced
open/close function. If 24VAC is applied, the circuits will
fail.
• If the same signal is input to multiple control motors that
are connected in parallel, faulty operation may result.
The same contact signal cannot synchronize multiple
ECM3000 motors.

AUXILIARY SWITCH OPTIONAL
Adjustment
lOperating point
An auxiliary switch can turn on if the arrow on the setting dial
(A, B, C, or D) is aligned with the mark.
The operating point can be set in a range of 5–95% opening.
The repeatability is within ±3%.
The differential is approximately 2%.
After the settings are changed, make sure that the switch oper-
ates before the motor reaches the fully-open and fully-closed
positions.
lOperation type
If the actual opening is greater than the set opening, connec-
tion between terminals 1 and 2 (Common–NO) will be electri-
cally continuous, but connection between terminals 1 and 3
(Common–NC) will not be.
The figure below shows an example in which, at 50% opening,
connection between terminals 1 and 2 is ON while connection
between terminals 1 and 3 is OFF.

*1. Feedback potentiometer output specifications
The feedback potentiometer of the ECM3000F has the following equiv-
alent circuit. (See the diagram of parallel resistors below.)
In the controller, the resistance of the feedback potentiometer is con-
verted to voltage, which indicates the motor opening.
In other words, the angle of rotation is not calculated directly from
the resistance of the potentiometer. But if a combination resistor
(1k+180) is used, the resistance can be close to 135, which has
been conventionally used in the industry.
The following are Azbil Corporation’s controllers compatible with
this device: SDC35/36, SDC45/46, the SDC40 series, DMC10, Network
Instrumentation Modules, RN748.

Note
• In old models, such as the M904, because the feedback
potentiometer uses a single resistor, if the resistance of the
potentiometer is measured (between terminals G and T)
with a continuity tester, the motor opening can be deduced.
However, the output part of the feedback potentiometer of this
device consists of multiple resistors. Thus, unlike old models,
its resistance is not proportional to the motor opening.
The controller calculates the motor opening from the voltage
between terminals G and T.
The voltage between terminals G and T is linear to the motor
opening, but if the resistance between these terminals is mea-
sured, as was possible for older models, the result will not be
linear to the motor opening. Instead, the relationship can be
graphed as a parabola, as shown below.
