※ 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.

·Before operating Ezi-STEP BT, thoroughly read this manual.

·After reading the manual, keep the manual near the Ezi-STEP BT so that any user can read the

manual whenever needed.

1. Precautions

◆ General Precautions

·Contents of this manual are subject to change without prior notice for functional im provement, change of

specifications or

user's better understanding. Thoroughly read the manual provided with the purchased

Ezi-STEP BT.

·When the manual is damaged or lost, please contact with Fastech's agents or our company 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.

·Although precaution is only a Attention, a serious result could be caused depending on the situation.

Follow safety precautions.

Attention : If user does not properly handle the product, the user may seriously or slightly injured

and damages may occur in the machine.

Warning : If user does not properly handle the product, a dangerous situation (such as an electric

shock) may occur resulting in deaths or serious injuries.

www.fastech-motions.com - 4

◆ Check the Product

Check the Product is damaged or parts are missing.

Otherwise, the machine may get damaged or the user may get injured.

Attention

◆ Installation

Carefully move the Ezi-STEP BT.

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.

Attention

Warning

◆ Connect Cables

Keep the rated range of lnput Voltage for Ezi-STEP BT.

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.

Attention

Warning

www.fastech-motions.com - 5

◆ Operation

◆ Check and Repair

If a protection function(alarm) occurs, firstly remove its cause and then release(alarm reset)

the protection function.

If you operate 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.

Stop to supply 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.

2. Main characteristics

3. Simple and Compact all-in-one Motor integrated with Drive

Saving installation space and ease of wiring by integrating drive circuits on the back side of a stepping motor.

3

Drive Output Signal Monitoring

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.

4

Improvement of High-Speed Driving

Depending on the speed of a stepping motor, Ezi-

STEP automatically increases the supply voltage 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.

Microstep and Filtering

The high-performance MCU operates at step resolutions

of 1.8 ° up to maximum 0.0072 ° (1/250 steps) and Ezi-

STEP adjusts PWM control signal in every 25 μsec,

which makes it possible for more precise current control,

resulting in high-precision Microstep operation.

High precision Microstep function and Filtering

Software Damping

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 MCU

adjusts the phase of the current according to the pole

position of the motor, drastically suppressing vibration.

This allows the smooth operation of the motor at high

speeds.
