This option is specifically designed to be used with the P2 Series variable
speed drive product range and is intended for professional incorporation into
complete equipment or systems. If installed incorrectly it may present a
safety hazard. TheP2 Series uses high voltages and currents, carries ahigh
level of stored electrical energy, and is used to control mechanical plant that
may cause injury. Close attention is required to system design and electrical
installation to avoid hazards in either normal operation or in the event of
equipment malfunction.
Please read the SAFETY NOTICE carefully, and all Warning and Caution boxes
elsewhere.
AP2 Drive fitted with this Option complies with the following standards:
!UL 840 Insulation Coordination for electrical equipment.
!IEC 664-1 Insulation Coordination within Low Voltage Systems.
P2 Series (ODP-2) Drives
WARNING
Within the European Union, all machinery in which this product is used must
comply with the Directive 89/392/EEC, Safety of Machinery. In particular, the
equipment should comply with EN60204-1.
WARNING
CAUTION is given where there is ahazard that could lead to damage to
equipment.
It is the responsibility of the installer to ensure that the equipment or system
into which the product is incorporated complies with the EMC legislation of
the country of use. Within the European Union, equipment into which this
product is incorporated must comply with 89/336/EEC, Electromagnetic
Compatibility
!Where the electrical supply to the drive is through aplug and socket
connector, do not disconnect until 10 minutes have elapsed after turning
off the supply.
!P2 drives and the Option Modules should be installed only by qualified
electrical persons and in accordance with local and national regulations and
codes of practice.
!Electric shock hazard! Disconnect and ISOLATE the P2 drive before
attempting any work on it. High voltages are present at the terminals and
within the drive for up to 10 minutes after disconnection of the electrical
supply.
!CE-marked for Low Voltage Directive.

LED STATUS INDICATION
The encoder module has 2 LEDs – LED A (Green) and LED B (Red).
LED A indicates power
LED B indicates a wiring fault condition.
The fault code is indicated on the drive display as noted above. For
transient faults, the LED will remain illuminated for 50ms to ensure
that fast transient faults can be observed.
OPERATION
Parameter Settings
When operating with an encoder, the following parameter settings
are required as a minimum:
P1-09: Motor rated frequency (found on the motor
nameplate).
P1-10: Motor rated speed (found on the motor nameplate).
P6-06: Encoder PPR value (enter value for the connected
encoder).
Closed Loop Vector speed provides full torque holding capability at
zero speed and enhanced operation at frequencies below 1Hz. The
drive, encoder module and encoder should be connected according to
the voltage rating of the encoder as shown in the wiring diagrams.
The encoder cable should be an overall shielded type, with the shield
bonded to earth at both ends.
COMMISSIONING
1) Enter the following parameters from the motor nameplate:-
P1-07 – Motor Rated Voltage
P1-08 – Motor Rated Current
P1-09 – Motor Rated Frequency
P1-10 – Motor Rated Speed
2) To enable access to the advanced parameters required, set P1-14 =
201
3) Select Vector Speed Control Mode by setting P4-01 = 0
4) Carry out an Auto-tune by setting P4-02 = 1
6) Check the Encoder Feedback value in P0-58. With the Optidrive
running in the forward direction, the value should be positive, and
stable with variation of + / - 5% maximum. If the value in this
parameter is positive, the encoder wiring is correct. If the value is
negative, the speed feedback is inverted. To correct this, reverse the
A and B signal channels from the encoder.
7) Varying the drive output speed should then result in the value of
P0-58 changing to reflect the change of the actual motor speed. If this
is not the case, check the wiring of the whole system.
8) If the above check is passed, the feedback control function can be
enabled by setting P6-05 to 1.
An application note, detailing full use of the Encoder interface module,
is available from your local Bardac distributor.

Whencommissioning, the P2 drive should firstly be commissioned in
Encoderless Vector Speed Control (P6-05 =0), and aspeed /polarity
check should then be made to ensure that the sign of the feedback
signal matches that of the speed reference in the drive. The steps
below show the suggested commissioning sequence, assuming the
encoderis correctly connected to the drive.
1) Option Module inserted into
P2 Drive Option Module Port
3) Ensure the option module is
fitted securely before powering
on the drive.
5) Once the Auto-tune is completed, the drive should be run in the
forward direction with alow speed reference (e.g. 2–5Hz).
Ensure the motor operates correctly and smoothly.
