Otherwise the Product may get damaged or User's foot may get injured
by dropping the product.
Use non-flammable materials such as metal in the place where the
Ezi-STEP BT is to be installed.
Otherwise, a fire may occur.
When installing several Ezi-STEP BT in a sealed place, install a
cooling fan to keep the ambient temperature of the Ezi-STEP BT as
50℃ or lower.
Otherwise, a fire or other kinds of accidents may occur due to
overheating.
The process of Installation, Connection, Operation, Checking and
Repairing should be done with qualified person.

Otherwise, a fire or other kinds of accidents may occur.
Cable connection should follow the wiring diagram.
Otherwise, a fire or other kinds of accidents may occur.
Before connecting cables, check if input power is off.
Otherwise, an electric shock or a fire may occur.
The case of the Ezi-STEP BT is insulated from the ground of the
internal circuit by the condenser. Ground the Ezi-STEP BT.
Otherwise, an electric shock or a fire may occur.
◆
Connect Cables
Warning
Attention
Warning
3 - www.fastech.co.kr
FASTECH Co.,Ltd.
Stop supplying power to the main circuit and wait for a while before
checking or repairing the Ezi-STEP BT.
Electricity remaining in the capacitor may cause danger.
Do not change cabling while power is being supplied.
Otherwise, the user may get injured or the product may get damaged.
Do not reconstruct the Ezi-STEP BT.
Otherwise, an electric shock may occur or the reconstructed product
can not get After-Service.
◆
Check and Repair
Warning
If a protection function(alarm) occurs, firstly remove its cause and
then release(alarm reset) the protection function.
If you are operating continuously without removing its cause, the
machine may get damaged or the user may get injured.
Do not make Motor Free and make input signal to ON during
operation.
Motor will stop and stop current will become zero. The machine may get
damaged or the user may get injured.
Make all input signals to OFF before supply input voltage to
Ezi-STEP BT.
The machine may get damaged or the user may get injured by motor
operation.
All parameter values are set by default factory setting value.
Change this value after reading this manual throughly.
Otherwise, the machine may get damaged or other kinds of accidents
may occur.

Sensorless Stall Detection
1
High precision Microstep function and Filtering (Patent pending)
The high-performance DSP operates at step resolutions of 1.8°up to maximum 0.0072°(1/250
steps) and Ezi-STEP® adjusts PWM control signal in every 25μsec, which makes it possible for
more precise current control, resulting in high-precision Microstep operation.

Software Damping

Detecting the loss-of-synchronization with
on-board DSP (Patent pending)
Ezi-STEP® can detect the loss-of-synchronization
of a stepping motor without the addition of an
external sensor. By monitoring the voltage, current,
and back-emf signal, the on-board DSP estimates
the current position of a rotor and enables it to
detect the loss-of-synchronization (an impossible
task for a conventional stepping motor drive), this
allows for high-speed operation at 100% torque
rating without loss-of-synchronization*.
*Effective only over 300rpm
Vibration suppression and high-speed op-
eration (Patent pending)
Vibration suppression and High-speed operation
(Patent pending) Motor vibration is created by
magnetic flux variations of the motor, lower current
from the drive due to back-emf from the motor at
high speeds and lowering of phase voltages from
the drive. Ezi-STEP® drive detects these problems
and the DSP adjusts the phase of the current
according to the pole position of the motor, drasti-
cally suppressing vibration. This allows the smooth
operation of the motor at high speed.
www.fastech.co.kr - 6
FASTECH Co.,Ltd.
Ezi-STEP® provides loss of step, run/stop, over-current, over-heat, over-voltage, power, and
motor connection alarms that can be monitored by the controller and visible by a motor-mounted
flashing led indicator.
Drive Output Signal Monitoring
4
Depending on the speed of a stepping motor, Ezi-STEP® automatically increases the supply volt-
age and prevents the torque lowering due to the low operating voltage to the motor caused by
back-emf voltage, this enables high-speed operation. Additionally, the software damping algorithm
minimizes the vibration and prevents the loss-of-synchronization at high-speed.
