Yaskawa K7 Manual [repack] Page
When the K7 drive detects an abnormality, it immediately halts operation, cuts power to the motor, and displays an error code on its front-panel LED display. Common Alarm Reference Table Alarm Code Alarm Name Probable Cause Corrective Action Main Circuit Parameter Error Corrupt internal memory or invalid parameters. Reset to factory defaults via the operator panel. A.10 Overcurrent Short circuit in motor wiring; damaged power transistor. Check U, V, W wiring for insulation breakdown. A.71 Overload (High Load) Motor operated beyond continuous rating; mechanical jam. Check mechanical mechanisms for binding or stiffness. A.84 Encoder Communications Error
: Analog voltage/pulse train, MECHATROLINK-III, or EtherCAT network commands. 2. Mechanical Installation and Environmental Constraints
Reduce mechanical friction, increase acceleration times, or upgrade to a higher torque motor. Encoder Communications Error yaskawa k7 manual
Pn20EPn210=16,777,216Load Travel per Motor Revolution (in User Units)the fraction with numerator Pn20E and denominator Pn210 end-fraction equals the fraction with numerator 16 comma 777 comma 216 and denominator Load Travel per Motor Revolution (in User Units) end-fraction 5. Autotuning and Commissioning Procedures
While manual keypad entry is possible, Yaskawa recommends using software. This PC-based tool allows you to: Graph real-time performance. Backup and restore parameters. Run mechanical analysis to identify resonance frequencies. Autotuning Modes When the K7 drive detects an abnormality, it
: Details the use of an operation-dedicated processor that achieves speeds of approximately 0.1µs per step .
Usually caused by sudden deceleration or high regenerative energy. Check mechanical mechanisms for binding or stiffness
This comprehensive guide serves as a roadmap to the , breaking down essential technical sections, wiring configurations, parameter settings, and troubleshooting protocols. 1. Document Architecture: Finding the Right Manual
Factory default: A jumper is installed between B2 and B3 for internal resistors.
