The following
procedure is a
supplement to
other
documentation
supplied with this
equipment and will
guide the user in
properly wiring the
A1000 and motor.
It will also show
the user how to
configure the
A1000 in open
loop vector mode
for a general
purpose
application.

Danger: Improper
wiring can and
will cause bodily
harm as well as
damage to the
equipment.

When installing the
system, be sure to
follow good wiring
practices and all
applicable codes.
Ensure that the
mounting of
components is
secure and that
the environment,
such as extreme
dampness, poor
ventilation, etc. will
not cause system
degradation.

Please read this
cheat sheet and
other
documentation
provided with the
A1000 thoroughly
before attempting
any installation.

Motor Rotation Test

In this step the motor is checked for proper direction and operation.
This test is to be performed solely from the digital operator. Apply
power to the A1000 after all the electrical connections have been
made and protective covers have been re-attached. At this point,

DO NOT RUN THE MOTOR, the Digital Operator should display as

shown in Fig. 3.

Fig. 3

Digital Operator

Use precaution, and
refer to Fig.1 or 2, swap
any two of the three
output leads to the motor
(U/T1, V/T2 and W/T3).
After the wiring change,
repeat Step 3 and
recheck motor direction.

After the power has been turned OFF, wait at least five
minutes until the charge indicator extinguishes completely
before touching any wiring, circuit boards or components.

DANGER

If motor rotation is not correct, then either reverse “Phase
Order” using parameter b1-14 or power down the drive, wait

five minutes and swap 2 motor leads.

Next, press to move the cursor one

position to the right and to increase the

frequency reference (d1-01) to 10.00 Hz.

Press to save frequency reference.

Next, press on the Digital Operator. The motor

should now be operating at low speed running in the correct
forward (clockwise) direction.

Next, press on the Digital Operator.

T1-04 Rated current (e.g. 11.0 A, 22.0 A)

T1-05 Rated Frequency (e.g. 60.0 Hz)

T1-06 Number of Poles (e.g. 4 Poles)

For standard AC motors

use the default setting for

motor base frequency

(60Hz), motor poles (4) and

motor rated speed.

T1-07 Rated Speed (e.g. 1750 rpm)

Press to select the next parameter and follow the same

procedure described above to adjust its value.

Warning! Sudden movement hazard. The A1000 and
motor may start unexpectedly during Auto-Tuning.

Warning! Electric Shock Hazard. High voltage will be
supplied to the motor when stationary Auto-Tuning is
performed. Do not touch the motor during auto-tuning.

Notice: Auto-Tuning will not function properly when a
brake is engaged on the load. Ensure the motor shaft
can freely rotate. Never perform an Auto-Tune with
motor connected to a load.

!

After setting parameter T1-07 press to select the

Auto-Tuning start command.

Next, press on the Digital Operator. The A1000

will now start the Auto-tuning procedure.

The display will show message ―Tune Successful‖ when the

Auto-Tuning procedure has been successfully completed.

Please reference the A1000 User Manual or repeat the

procedure again if the display shows an error message.

Fig.1 & 2 below show the electrical connections for the

input power and motor terminals for various A1000 models.
Select the proper diagram for the model you are installing
(see Step 1). WITH POWER OFF make the appropriate
connections.

Make sure to follow good wiring practices and all
applicable codes. Ensure that the equipment is
grounded properly as shown in fig. 1

DANGER; LETHAL VOLTAGES ARE PRESENT- Before
applying power to the A1000, ensure that the terminal
cover is fastened and all wiring connections are secure.
After the power has been turned OFF, wait at least five
minutes until the charge indicator extinguishes
completely before touching any wiring, circuit boards or
components.

!

Make sure the A1000 has been properly sized for single phase input
power. For best performance, the drive input supply voltage must be at
least equal to or greater than the motor rated voltage.

To make sure you received the correct model, it is

essential to verify the A1000 nameplate with your order

and make sure the A1000 has the correct rating so it can

be used with your motor. Please check the nameplate

information as shown in the example below.

· Check that the available power will meet the input
power requirements.

· Ensure that the output power from the A1000 is

compatible with the motor requirements.

Mounting the A1000

· In the case of systems with more than one A1000, follow
the above procedure for each A1000 and motor.

The mounting of the A1000 is extremely important regarding
environment and accessibility. Depending on your system,
there are various models available and the mounting
dimensions (footprint) may be different. Because the
mounting procedure is fairly extensive, it is beyond the scope
of this document; the user is referred to the A1000 User
Manual (Document No. SIEP C710606 21A) received with
the A1000, Section 2.2 Mechanical Installation. Match the
model that you received and follow the procedure described
in the manual to ensure a safe and functional installation. In
cases where the system has more than one A1000, refer to
the proper clearances required for adequate ventilation.
Please pay particular attention to:

· The clearances to be maintained around the enclosure

for adequate ventilation.

· The environmental specifications such as avoiding
excessive dampness, extreme temperatures, chemical
exposure, corrosive areas, etc. to avoid damage to the
equipment and to maintain safety.

Removing and Attaching the Terminal Cover

Improper removal of the A1000 terminal cover as well as
front cover can cause extensive damage to the A1000. To
avoid damage to these items, please pay particular attention
to the A1000 User Manual, Document No. SIEP C710606
21A, Section 3.5, Removing and Attaching the Terminal

Cover.
