Warning and precautions
!
Installation
The drive unit should be installed in well ventilated and safe perfect electric cabinet. It
is suggested that the recommended interval is employed in Fig 1 to get the excellent
heat dissipation.
Wiring
The wiring must be stable and terminal must be tightened when the motor line and
power line have big current. The drive unit and stepper motor must be earthed stably.
Power-on
Do not plug out/plug in the plug with the electricity, otherwise, the unexpected result
maybe occur.
The overcurrent protector should be installed to protect the power line from being cut
off when the overcurrent occurs.
The power switch should be employed with the air switch instead of the general
knife-break switch.
The drive unit is turned on when there is no conductive abnormal thing in the drive
unit, and the wiring is correct and stable.

2 Performance introduction
The three-phase compound stepper motor is adopted with the rare earth material, with
little exhaustion of electromagnetism, high coversion efficiency and excellent
dynamism compared to other reaction stepper motor. The three-phase compound
stepper can stably run with low noise, big output and without stepping out. The
three-phase stepper motor greatly improves the vibration and noise driven by the sine
wave current, and is the top grade motor.
DY3E series three-phase compound steppr drive unit developed by GSK CNC
Equipment has characteristics as follows:
Latest innovative technology
It is employed with the micro-electronic technology to embed the new generation high
speed monolithic processor into the drive unit to improve the control performance and
simplify the circuit; employed with AC servo control method to get AC servo run
characteristics, and the three-phase sine current drive output; the low voltage DC
power supply in the drive unit use the switch power supply to reduce the volume of
power circuit and to get the reliable stability.
Micro stepping angle
It is employed with the vector division technology to control the min. angle of the motor
rotating to be 1/20（0.03°）of the stepping angle of motor. The mircro step control can
ensure the stepper motor can stably run with low speed, and its run effect approaches
that of AC servo. The micro step drive unit is matched with μm（0.001mm） grade
CNC control device to realize μm grade min. movement, used for machining the
cambered surface, conical surface, thread and other workpiece, which can obviously
improve the fine effect of workpiece’s surface.

High torque
The output torque of stepper motor is in direct proportion, the input current capacity is
in direct proportion of voltage used by the amplifier of drive unit when it runs with the
high speed. Presently, the used voltage of most stepper motor is below DC150V, but
that of DY3E reaches DC310V, so, it still has the high torque output when it runs with
the high speed.
High reliability
The control parts are high integrated, the amplifier is employed with Mitsubishi new
intellective module with tight structure, terse circuit, few connectors, external wind
cooling heat dissipation to protect the dust from the machine inner, and with the
over-temperature, overvoltage, low-voltage, protection and alarm signal output.

4 Advanced stepper motor control method
The AC servo control method is applied the drive unit of three-phase compound
stepper motor, its input AC220V becomes to DC 310V after commutating, and then
becomes three-circuit 310V stepping sine wave current after pulse width modulation,
and their fixed time sequence separately flows through three-circuit wind, and each
step corresponds to one step of motor rotating. Change the motor’s speed by
changing the frequency of sine current output by drive unit, and step amount output
by per rev confirms the angle of every step rotating.
According to the present electronic technology, the step amount of sine current is
divided into many. According to the theory, the step amount per rev is many, which is
the subdivided technology. The theory analysis and much experiement verify: when
the subdivision amount exceeds 10, the skip and the step-out appear after the motor
has the load. So it is no actual meaning when the subdivision amount exceeds 10.
Presently, only three-phase sine current subidivision technology can ensure that the
motor output torque does not drop after subsidivision, and each step can be precisely
positioned.
When the three-phase wind is connected with the sine current(three-phase current
phase shift is 120°）, the current in the air gap of motor creates constant rotary
maganetic potential of one space maximum value, the space maganetic potential
power and direction are related to the current ‘s sequence and power of each phase,
the current of drive unit in the motor wind is bidirectional grade step wave(the current
wve forms the sine wave when the grade amount increases infinitely), and the phase
difference of each current is 120°. The maganetic rotor tracks the rotor space
maganetic potential face to move to form the motor rotating, and when the space
maganetic potential positions to some point, the rotor also positions to the point to
realize the precise positioning. The relationship between phase current waveform and
the stepping angle is as follows:

When some phase current changes one full period(other phase current also
separately changes one full period, only their stepping angle is different), the rotor of
stepping motor rotates one pitch, and its corresponding mechnical angle is
360°/Z2(Z2 is the teeth number of rotor). When the phase current is divided into N
step current value in one period, the rotor is located at the different positioning point
when it is in each step current, so the stepping angle of stepper motor
is :а=360°/(NZ2), or the step number per rev of motor is S=N×Z2. When each sine
period is composed of 20 current step N, and the teeth number Z2 of rotor is 50, the
stepping angle of motor isа=360°/(NZ2)=360°/（20×50）=0.36°, the needed pulse
number per rev is S=N×Z2=20×50=1000.

5 Installation specifications
The contour and installation dimension is as Fig. 1.
Installation steps:
a) Unpack check
DY3E drive unit is packed solely. Please check the drive unit type, serial number,
User Manual, accessories and so on after unpacking, and contact with us if they are
be inconsistent with those in the packing box.
Check whether the drive unit distorts, its parts are abnormal, and if they are so,
install them after they are safety or contact with us.
b) Installation
DY3E drive unit should be installed in the excellent ventilated and perfect guard
electric cabinet, and please install it according to recommended interval as Fig. 1 to
get the excellent heat dissipation of drive unit.
c) Wiring
Connect the signal wire, motor wire and powe wiring according to the following
interface specifications. The wiring must be connected stably and the motor wiring
and power wiring should be more than 1 mm
2
.
Because the drive unit works in the high frequency chopping mode, the stepper
motor will have the induced voltage and leak the current. It is suggested that the
power supply of drive unit should be provided by the insolated transformer, and the
drive unit and the stepper motor must be stably earthed to get the safety. The power
switch should select the air switch, leakage protection switch or contactor to get the
rapid and reliable power-on or power-off.

2）Motor interface and power interface
When the power input is AC 220V, the power supply is connected to r, t from L, N.
The internal coil of stepper motor likes a star, and its outgoing line can be connected
to U, V, W arbitrarily. We should turn off the power supply when the motor rotates in
the mistake direction, and then change the connector position of 2 lines arbitrarily.
3）Status indicator
The drive unit alarms when the yellow alarm indicator ALM is ON. 4 green indicators:
RDY is ready indicator, and it runs normally when it is ON; A, B, C six indicators are
for pulse input status, their initial status are that of two axes before power-down. A, B,
C have 8 kinds of status, we can judg whether the machining process is step-out
based on that their statuses are same in the machine zero before machining or in the
machine zero return after machining.
4）Dial switch
