What are the possible causes of motor overload in Emerson EV2000-4T0055G/0075P DC Drives?
- A
  Anne HarrisSep 2, 2025
  If your Emerson DC Drives indicate a motor overload, it could be due to an improper V/F curve; set the V/F curve and torque boost value correctly. Check the AC supply voltage, as low voltage can cause this. If a common motor has operated with a heavy load at low speed for a long time, use a special motor designed for continuous operation. Also, the motor’s overload protection threshold might be improper, so modify it. Finally, check the load, as fast load changes can contribute to this issue.

What to do for over voltage in constant-speed operation of Emerson EV2000-4T0055G/0075P?
- A
  Amanda ChandlerAug 31, 2025
  If you're encountering over voltage during constant-speed operation with your Emerson DC Drives, check the AC supply voltage for any abnormalities. Also, a too short Acc/Dec time could be the cause, so prolong the Acc/Dec time. If there's an abnormal change in input voltage, install an input reactor. If the load inertia is too big, use a suitable dynamic braking kit.

How do I troubleshoot over voltage during acceleration with Emerson EV2000-4T0055G/0075P?
- J
  Jean WyattAug 29, 2025
  If you're experiencing over voltage during acceleration in your Emerson DC Drives, it might be due to an abnormal AC supply voltage; check the AC supply voltage. Another cause could be a too short Acc/Dec time, so try prolonging the Acc time. Also, if the motor restarts after the drive stops instantly, set F2.00 to the “start on fly” function.

What causes drive overload in Emerson EV2000-4T0055G/0075P DC Drives and how to fix it?
- H
  Hannah TownsendAug 27, 2025
  If your Emerson DC Drives show a drive overload, it could be due to several reasons. The Acc/Dec time might be too short, so prolong it. If the DC injection braking current is too big, reduce it or prolong the braking time. An improper V/F curve can also cause this, so adjust the V/F curve or torque boost value. If the motor restarts instantly after stopping, set the starting mode (F2.00) to “start of fly”. Check for low AC supply voltage. Finally, the load might be too heavy, so select a drive with bigger power.

How to resolve over-current during deceleration in Emerson DC Drives?
- A
  anthonypageAug 27, 2025
  If you're experiencing over-current during deceleration with your Emerson DC Drives, it could be because the deceleration time is too short; try prolonging the Dec time. Alternatively, the load might be generating energy or the load inertial might be too big, in which case you should connect a suitable braking kit. Also, consider whether the drive's power is too low and select a drive with bigger power if necessary.

Why is there over voltage during deceleration in Emerson EV2000-4T0055G/0075P DC Drives?
- P
  Patrick KingAug 25, 2025
  If you're facing over voltage during deceleration with your Emerson DC Drives, the deceleration time may be too short, especially concerning generated energy; try prolonging the Dec time. Additionally, if the load generates energy or the load inertial is too big, consider using a suitable dynamic braking kit.

What to do if there is over-current in constant speed operation in Emerson EV2000-4T0055G/0075P?
- J
  Joseph ReyesAug 22, 2025
  If your Emerson DC Drives experience over-current during constant speed operation, it might be due to a sudden load change, so try to reduce the change of the load. Also, check if the Acc/Dec time is too short and prolong it if needed. Examine the load for any abnormalities. Verify the AC supply voltage, as a low voltage can cause this issue. Finally, the drive's power might be insufficient, so consider selecting a drive with bigger power.
