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.
Digital Operator
turned off.

10.00 Hz
In this step the A1000 is setup for use with the motor. Make sure
all protective covers have been re-attached then apply power to
the A1000. D
DO NOT RUN THE MOTOR.
From the main reference press once until the Digital
Operator shows the Auto-Tuning menu then press
Press once until the Digital Operator shows parameter
T1-02 Mtr Rated Power then press
Digit Flashing
Press to select the digit you would like to change and
use to adjust value and press to save.
Enter Motor Power in kW (Kilowatt)
Motor HP to kW = HP x 0.746
Example: 10HP = 10 x 0.746 = 7.46 kW
T1-04 Rated Voltage (e.g. 230 V, 460 V)
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.

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 Technical
Manual (Document No. SIEP C710616 41) 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 Technical Manual,
Document No. SIEP C710616 41, Section 3.5, R
