Speed Deviation on the YASKAWA Media Converter (for Control Mode with PG) happens when, after speed agreement is reached, the deviation between the speed detection value for the pulse input and the speed reference exceeds the setting value of F1-10 for the time set in F1-11 or longer when the Operation Selection at Deviation was set to continue operation (F1-04 = 3).
How to reduce motor noise in YASKAWA Controller?
If you're experiencing motor noise with your YASKAWA Controller, try increasing the carrier frequency. If motor hunting and oscillation occur at low speeds, reduce the carrier frequency.
What to do if YASKAWA U1000 Controller motor hunting and oscillation at speeds up to 40 Hz?
If you notice motor hunting and oscillation at speeds up to 40 Hz with your YASKAWA Controller, increasing the carrier frequency may help if the motor noise is too loud. Alternatively, lowering the carrier frequency can also address this issue.
How to improve torque and speed response on YASKAWA U1000 Controller?
If your YASKAWA Controller exhibits poor torque or speed response, gradually increase the ASR gain setting in increments of 5 if motor torque and speed response are too slow. Reduce the setting if motor hunting and oscillation occur.
How to fix motor hunting and oscillation between 10 and 40 Hz on YASKAWA U1000?
If your YASKAWA Controller experiences motor hunting and oscillation at speeds between 10 and 40 Hz, try the following: reduce the setting if insufficient motor torque relative to the size of the load causes hunting; increase the setting when motor hunting and oscillation occur with a light load; reduce the setting if hunting occurs when using a motor with a relatively low inductance, such as a high-frequency motor or a motor with a larger frame size.
How to improve speed precision on YASKAWA Controller?
If your YASKAWA Controller demonstrates poor speed precision, gradually increase the setting in 0.1 ms increments if the speed is too slow. If the speed is too fast, gradually reduce the setting in 0.1 ms increments.
How to resolve low torque and speed response issues on YASKAWA U1000 Controller?
If you're having motor performance issues related to low torque and speed response with your YASKAWA Controller, gradually increase the setting if the load torque and speed response are too slow. Also, gradually increase the setting if motor hunting occurs due to load inertia.
How to fix poor speed precision during regenerative operation in YASKAWA U1000?
To improve speed precision during regenerative operation on your YASKAWA Controller, enable slip compensation during regeneration by setting parameter C3-04 = 1.
What causes a YASKAWA Media Converter to display Power Supply Undervoltage?
The YASKAWA Media Converter shows a Power Supply Undervoltage error if the input power supply voltage drops to or below the Input Power Supply Undervoltage Detection Level (L2-21).
What causes MEMOBUS/Modbus Communication Error on YASKAWA Media Converter?
A MEMOBUS/Modbus Communication Error on the YASKAWA Media Converter occurs because control data was not received for the CE detection time set to H5-09.
