the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
SAFETY INSTRUCTIONS
7
SD700 – ENCODER BOARD
POWER ELECTRONICS
Wiring and periodic inspections should be performed at least 10 minutes
after disconnecting the input power and after checking the DC Link
voltage is discharged with a meter (below 30VDC).

WARNINGS
RECEPTION
 Material of Power Electronics is carefully tested and perfectly packed
before leaving the factory.

In the even of transport damage, please ensure that you notify the
transport agency and POWER ELECTRONICS: 902 40 20 70
(International +34 96 136 65 57) or your nearest agent, within 24hrs
from receipt of the goods.

UNPACKING
 Make sure received merchandise corresponds with delivery note,
models and serial numbers.

Each board is supplied with a technical manual.
RECYCLING
 The packing of the drives must be recycled. For this reason it is
necessary to separate different materials (plastics, paper, cardboard,
wood, …) and settle them in corresponding containers.

The residual parts of electrical devices must be collected in a selective
manner in order to warranty the correct environmental treatment.
SAFETY
 Before operating the drive, read this manual thoroughly to gain and
understanding of the unit. If any doubt exists then please contact
POWER ELECTRONICS, (902 40 20 70 / +34 96 136 65 57) or your
nearest agent.

Wear safety glasses when handling the product with power applied
and the front cover is removed.

Handle the product with care according to its weight.

Do not place heavy objects on the product.

Install the product according to the instructions described in this
manual.

SAFETY

Ensure that the mounting orientation is correct.

Do not drop the product or subject it to impact.

The SD700 drives contain static sensitive printed circuits boards. Use
static safety procedures when handling these boards.
CONNECTIONS PRECAUTIONS
 To ensure correct operation of the inverter it is recommended to use a
SCREENED CABLE for the control wiring.
 For EMERGENCY STOP, make sure supply circuitry is open.
 Do not disconnect motor cables if input power supply remains
connected. The internal circuits of the drive will be damaged if the
incoming power is connected and applied to output terminals (U, V,
W).
 It is not recommended to use a 3-wire cable for long distances. Due to
increased leakage capacitance between conductors, over-current
protective feature may operate malfunction.
 Do not use power factor correction capacitors, surge suppressors, or
RFI filters on the output side of the inverter. Doing so may damage
these components.
 Always check whether the DC Link LED is OFF before wiring
terminals. The charge capacitors may hold high-voltage even after the
input power is disconnected. Use caution to prevent the possibility of
personal injury.
COMMISSIONING
 Follow the steps described in this manual.
 Always apply voltage and current signals to each terminal that are
within levels indicated within this manual. Otherwise, damage to the
optional board may result.

OPERATION PRECAUTIONS
 When the Auto Restart function is enabled, keep clear of driven
equipment, as the motor will restart suddenly after a fault is reset.
 The “STOP / RESET” key on the keypad is active only if the
appropriate function setting has been made. For this reason, install a
separate EMERGENCY STOP push button that can be operated at
the equipment.
 If a fault reset is made with the reference signal still present then a
restart will occur. Verify that it is permissible for this to happen,
otherwise an accident may occur.

 Do not modify or alter anything within the drive.

Before programming or operating the SD700 Series, initialise all
parameters back to factory default values.
EARTH CONNECTION
 The drive is a high frequency switching device, and leakage current
may flow. Ground the drive to avoid electrical shock. Use caution to
prevent the possibility of personal injury.

Connect only to the dedicated ground terminal of the drive. Do not use
the case or the chassis screw for grounding.
 When installing, grounding wire should be connected first and
removed last.
 The earth cable must have a minimal cross sectional area that meets
local country electrical regulations.
 Motor ground must be connected to the drive ground terminal and not
to the installation‟s ground. We recommend that the section of the
ground connection cable should be equal or higher than the active
conductor.

Installation ground must be connected to the drive ground terminal.

1. INTRODUCTION
1.1. Description of Encoder Board
The optional Encoder board offers to drives of SD700 Series the
possibility of connecting 2 incremental encoders: one encoder for the
vector control and the other one for the process control, operating from
5 to 24VDC, according to the requirements.
The implementation of the Encoder board is directly done over the own
control board of the drive, for this, an additional space is not need
when installing this board.

6. COMMISSIONING
Once the Encoder board is connected and the encoder is fitted on the motor
shaft, and after programming the parameters described in the previous
section, the following steps are recommended:
 Accessing to the motor shaft
1. With the drive in „ON‟ status, select the control type „Closed Loop‟,
by setting the parameter G19.3.2 to „Y‟.
2. Turn over the motor shaft manually in positive rotation direction
(clockwise). In order to check the rotation direction, look at how to
change the motor shaft speed in %. This value is shown in the top
left corner of the display, concretely in „Status Line‟. In this way:
o If the speed value is positive, the motor shaft is rotated in
positive direction.
o If the speed value is negative, turn over the motor shaft in
opposite rotation direction.
o If the value does not change, there is some problem with the
encoder (not operating correctly, not receiving power, wiring
error, ...).
3. Turning over the motor shaft in positive rotation direction, check the
number of encoder pulses, visualizing the parameter „SV1.13 
Encod.Puls‟, in visualization parameter group „SV1 – Motor
Visualization‟.
o If the number of pulses increases, then the encoder is correctly
connected.
o If the number of pulses decreases, exchange the connection of
signals A by /A (inverse polarity). After this, check that the
number of pulses is now increasing when the motor shaft is
rotating in positive direction.
26
COMMISSIONING
POWER ELECTRONICS
SD700 – ENCODER BOARD
 Without accessing to the motor shaft
1. With the drive in „ON‟ status, select V/Hz as control type. For this, set
the parameter G19.3.2 to „N‟ and the parameter G19.1.1 to „V/Hz‟
(see ‘Getting Started Manual’ of SD700).
2. Introduce a positive speed reference, in parameter G3.3 (see
‘Getting Started Manual’ of SD700).
3. Give the start command to the drive (by keypad, by digital input or by
communications).
4. Check that the number of received pulses from the encoder
increases, visualizing the parameter SV1.13, and that the motor
speed value in rpm displayed in parameter SV1.2 (see ‘Getting
Started Manual’ of SD700) is similar to the speed value displayed in
parameter SV1.14. This means that the encoder is correctly
connected and operates properly.
On the other hand, if the number of pulses decreases, and therefore
the speed value is negative in parameter SV1.14, exchange the
connection of signals A by /A (inverse polarity). Now, check that the
number of pulses increases and the speed value is positive.
In case that neither the number of pulses nor the speed (SV1.14)
change, there is some problem with the encoder (not operating
correctly, not receiving power, wiring error, ...).

Frequently Answers and Questions

How do I connect an encoder to the SD700 drive?
The SD700 drive has an optional Encoder board which can be installed. Use the instructions in the manual to connect the encoder to the board and then connect the board to the drive. Ensure the input voltage for the encoder is set correctly.
What kind of encoders are supported by the SD700 drive?
The SD700 drive supports incremental encoders with open collector output, voltage, or 'push-pull' outputs. The input voltage can be set to 5VDC or 24VDC.
What are the fault codes related to the encoder?
The SD700 drive displays two possible fault codes related to the encoder: F38 ENCODE LOSS, which means the encoder signal is lost, and F39 ROTOR LOCKED, which indicates the encoder signal is not received after a start command. The manual provides instructions on troubleshooting these faults.
