To Next PageTo Next PageWhy is the motor current large in my Mitsubishi Electric Inverter?
A large motor current in your Mitsubishi Electric Inverter may be due to a load that is too heavy. Another possible cause is that the torque boost setting is too large, which activates the stall prevention feature. Check these settings to resolve the issue.
Why does the speed greatly differ from the setting on my Mitsubishi Electric FR-E520S Inverter?
If the speed of your Mitsubishi Electric Inverter differs greatly from the setting, verify that the frequency setting signal is correct. Also, ensure that parameters Pr. 39, Pr. 245, and Pr. 902 to Pr. 905 are set correctly. Finally, check that the input signal lines are not affected by external cables.
How to fix unsmooth acceleration/deceleration on Mitsubishi Electric Inverter?
To address unsmooth acceleration or deceleration on your Mitsubishi Electric Inverter, first, check the acceleration and deceleration time settings. Also, verify that the load isn't too heavy.
What to do if the motor remains stopped on Mitsubishi Electric Inverter?
If the motor remains stopped on your Mitsubishi Electric Inverter, check the main circuit, the input signals, and the parameter settings. Also, check the load, and examine the ALARM lamp and error display for any indications.
Why speed does not increase on Mitsubishi Electric FR-E520S Inverter?
If the speed is not increasing on your Mitsubishi Electric Inverter, verify that the maximum frequency is set correctly. Also, check to ensure that the load isn't too heavy.
What to do if operation mode is not changed properly on Mitsubishi Electric FR-E520S?
If the operation mode is not changing properly on your Mitsubishi Electric Inverter, check that the STF or STR signal is off. Also, verify the Pr. 79 setting.
Why is Mitsubishi Electric FR-E520S Inverter motor rotating in the opposite direction?
If the motor of your Mitsubishi Electric Inverter is rotating in the opposite direction, verify that the phase sequence of the output terminals is correct.
Why is the operation panel display not operating on my Mitsubishi Electric FR-E520S Inverter?
If the operation panel display is not operating on your Mitsubishi Electric Inverter, first, ensure that the operation panel is securely connected. Next, check for a short circuit across terminals PC-SD.
Why does the speed vary during operation of my Mitsubishi Electric Inverter?
Speed variations during operation of your Mitsubishi Electric Inverter can occur for several reasons: * The load might be varying. * The frequency setting signal may be unstable or affected by noise. * An undesirable current may be causing a malfunction. * The applied motor capacity setting (Pr. 80) might not be correct for the inverter's capacity. * The wiring length might exceed 30m in general-purpose magnetic flux vector control or be incorrect for V/F control. Check each of these possibilities to identify the cause.
Why parameter write cannot be performed on Mitsubishi Electric Inverter?
If you cannot write parameters on your Mitsubishi Electric Inverter, ensure that operation is not currently being performed. Also, verify that you pressed the SET key (WRITE key) and that you are not attempting to set a parameter outside of its allowed range or in the wrong operation mode.
