Connect directly to the motor phases. Ensure proper phase rotation to match the intended direction of travel.
Access the T1 parameter group to initiate rotational or stationary auto-tuning. This process automatically measures motor winding resistance and inductance to optimize torque performance. 5. Troubleshooting and Fault Codes
The digital operator allows you to access the drive's parameter structure. Parameters are grouped by function (e.g., A for Initialization, B for Application, C for Tuning). Essential Parameter Checklist Parameter Code Description Recommended Setting / Action Access Level Set to 2 (Advanced Level) to view all parameters. A1-02 Control Method Selection yaskawa k1000 manual
Measure the incoming line-to-line voltage. Inspect upstream contactors, fuses, and disconnect switches for loose connections or pitted contacts. oL1 (Motor Overload)
Here is the essential text setup for the Yaskawa GA800 (K1000 Series): Connect directly to the motor phases
Check if the physical LED indicators on the control board match the state of the digital operator.
If you tell me if you are looking for the full PDF , a specific error code , or wiring diagrams , I can help you locate the right document. Alternatively, let me know if you need to know about: Specific parameters for induction motors Encoder wiring diagrams Braking resistor calculations Share public link Parameters are grouped by function (e
| Fault Code | Display on Keypad | Meaning | Likely Fix (per manual) | | :--- | :--- | :--- | :--- | | | Overcurrent | Short in motor or cables | Check insulation resistance. Increase C1-01 (accel time). | | ov | Overvoltage | Deceleration too fast | Increase C1-02 (decel time). Install braking resistor (check manual section 3.9). | | UV1 | Undervoltage | Input power dip or phase loss | Check incoming fuses. Measure L1-L2-L3 voltage. | | HE | Heatsink Overheat | Clogged fan or high ambient | Clean cooling fins. Check if F4-01 (fan life) is at end. | | bUS | Option Communication Error | Modbus/network disconnected | Check wiring on terminals R+/R-. Cycle power on controller. | | STo | Safe Torque Off | Safety circuit open | Check terminals H1-HC and H2-HC for 24V signal. |
