Yaskawa K1000 Manual Jun 2026

Connect these terminals directly to the three-phase AC motor.

Working with a Yaskawa K1000 VFD? Don't rely on the "Quick Start" guide. You need SIEP C710606 31 . Key parameters most techs miss: L3-04 (Stall Prevention during decel) and n2-02 (AFR gain). If you are tuning for a 30HP centrifugal pump, set n2-02 to 0.8 instead of the default 1.0 to stop the head pressure oscillations. #Yaskawa #VFD #HVAC #LegacyEquipment

The factory was silent again, but Elias knew the truth: as long as someone held the manual, the machines would never truly be silent. yaskawa k1000 manual

Cause: The drive output current exceeded the overcurrent detection level due to a short circuit, grounding fault, or excessively heavy load.

0.01 to 590 Hz (higher frequencies available on custom firmware) Connect these terminals directly to the three-phase AC motor

Disconnect all power before servicing. Wait at least 5 to 10 minutes for the internal capacitors to discharge fully. Verify zero voltage across the DC bus terminals (+ and -) using a multimeter.

Form-C dry contacts that change state when a drive fault occurs, allowing integration into master safety PLLs or PLCs. 4. Key Parameter Configurations You need SIEP C710606 31

Summary:

Measure the incoming AC line-to-line voltage to ensure it falls within the drive's acceptable nominal tolerance. oL1 (Motor Overload)

Fix: Check motor insulation, check wiring for short circuits, or increase acceleration time ( C1-01 ).
