※ Before operation ※

●

Thank you for your purchasing Ezi-STEP BT.

●

Ezi-STEP BT is an all-in-one Unit. For high-speed and high-precision drive of a stepping

motor, Ezi-STEP BT is an unique drive that adopts a new control scheme owing to an

on-board high-performance 32bit digital signal processor.

●

This manual describes handling, maintenance, repair, diagnosis and troubleshooting of Ezi-

STEP BT.

●

at the address on the last page of the manual.

●

Our company is not responsible for a product breakdown due to user's dismantling for the

product, and such a breakdown is not guaranteed by the warranty.

◆

Put the Safety First

●

Before installation, operation and repairing the Ezi-STEP BT, thoroughly read the manual and

fully understand the contents. Before operating the Ezi-STEP BT please, understand the

mechanical characteristics of the Ezi-STEP BT and related safety information and precautions.

●

This manual divides safety precautions into Attention and Warning.

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

3

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.
