Why does my YASKAWA Inverter motor stop and not output torque?
- B
  Brianna RossJul 31, 2025
  The motor might stop and not output torque due to several reasons: * The stall prevention level during acceleration might be too low. Check if the stall prevention level during acceleration (n093) is set to an appropriate value. * The stall prevention level during running might be too low. Check if the stall prevention level during running (n094) is set to an appropriate value. * The load could be too heavy, activating stall prevention. Lengthen the set acceleration time (n019) or reduce the load. * Changing the maximum frequency might have inadvertently changed the maximum voltage frequency. To increase the speed of a general-purpose motor, only change the maximum frequency. * The V/f set value might be too low. Set the V/f (n011 to n017) according to the load characteristics.

What to do if YASKAWA VS-606V7 Inverter digital operator does not turn ON?
- M
  Marisa GonzalesAug 5, 2025
  If the digital operator does not turn on, here are a couple of potential causes: * The power may not be supplied. Check if the breaker or another component on the power input side is turned ON. * The digital operator may not be correctly mounted. Ensure the digital operator is mounted correctly.

Why is the LED of my YASKAWA VS-606V7 Inverter Digital Operator unlit?
- S
  Stacey JenkinsAug 16, 2025
  If the LED on the Digital Operator isn't lit, first, check that the power is being supplied to the Inverter. Ensure that the breaker or relevant power input component is turned ON. Next, verify that the Digital Operator is correctly mounted. Also, check the connection of the short-circuit bar for terminals +1 and +2. If the POWER charge indicator lamp lights but the Digital Operator still shows no display after turning on the power, the main circuit fuse may be blown, requiring replacement of the Inverter.

How to fix unstable motor speed on a YASKAWA VS-606V7 Inverter?
- D
  Douglas PatelAug 20, 2025
  If your motor speed fluctuates, especially with a light load, there are several potential causes. Check the Stall Prevention Level during Running (n094) to ensure it's appropriately set. A load that is too heavy could also trigger stall prevention. Additionally, consider decreasing the carrier frequency (n080). If the V/f set value is too high for low-speed operation, adjust the V/f settings (n011 to n017) to match the load characteristics. Verify that the maximum frequency (n011) and maximum voltage frequency (n013) are correctly set according to the motor specifications. Also, avoid using the V7 Inverter for operations at 1.5 Hz or less. Finally, if the analog reference input is unstable, increase the filter time constant (n062).
