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 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. An application note, detailing full use of the Encoder interface module, is available from your local Invertek distributor. ERROR CODE DEFINITIONS The following error codes are related to the encoder operation: Code Description Solution Communication loss No communication between the encoder module and the drive. Please check the module is properly fitted into the slot. Speed feedback error exceeds level set in P6- 07 The estimated motor speed differs from the measured motor speed. Check encoder connection, wire shielding, and values set in P6-07. Encoder PPR motor speed mismatch The encoder used must have a PPR value of at least 60. Motor nameplate RPM must be entered in P1-10 Encoder Channel A Fault Error normally caused by encoder wiring error. Check encoder wiring and commissioning guidelines.
