SAFETY
This option is specifically designed to be used with the Optidrive P2 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. The Optidrive P2 uses high voltages and currents, carries a high 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.
System design, installation, commissioning and maintenance must be carried
out only by personnel who have the necessary training and experience. They
must read carefully this safety information and the instructions in this Guide
and follow all information regarding transport, storage, installation and use of
the Option module, including the specified environmental limitations.
Please read the SAFETY NOTICE carefully, and all Warning and Caution
boxes elsewhere.
CAUTION
Store the Optidrive Option Module in its box until required. It should be stored
in a clean and dry environment. Temperature range –40oC to +60oC.
Install the Option Module into the Optidrive by inserting the module into the
option module port of the Optidrive as shown in the mechanical installation
section. Do not use undue force in inserting the option module into the port.
WARNING
Optidrives 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 Optidrive 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.
Where the electrical supply to the drive is through a plug and socket
connector, do not disconnect until 10 minutes have elapsed after turning off the
supply.

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.
Note: Encoder Vector Torque Control and Encoder V/F speed control operation
is detailed in the Optidrive P2 Encoder Speed control application guide.
The encoder cable should be an overall shielded type, with the shield bonded to
earth at both ends.
COMMISSIONING
When commissioning, the Optidrive should firstly be commissioned in
Encoderless Vector Speed Control (P6-05 = 0), and a speed / 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 encoder is correctly connected to the
Optidrive.
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
5) Once the Auto-tune is completed, the Optidrive should be run in the forward
direction with a low speed reference (e.g. 2 –5Hz). Ensure the motor operates
correctly and smoothly.
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.
