from T1 does not exceed 100mA.
NOTE 0V of encoder must also be connected to drive 0V (T7).
NOTE Do not connect the encoder cable shield to 0V of the drive or

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
When commissioning, the Optidrive should firstly be commissioned in
Encoder less 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.
