What to do if TECO JSDEP-50A Servo Drives show over-voltage error?
- B
  Brent DuncanAug 19, 2025
  If your TECO Servo Drive displays an over-voltage (regeneration error), it means the main circuit voltage has exceeded the maximum allowable value (410V). First, use a multimeter to check if the input voltage is within the specified limit. Next, verify that Parameter Cn012 is set correctly. If the alarm appears during operation, extend the acceleration/deceleration time or reduce the load ratio within the permitted range. If the problem persists, an external regeneration resistor might be needed.

What to do if TECO JSDEP-50A Servo Drives show motor overload?
- J
  Joseph VelasquezAug 21, 2025
  If your TECO Servo Drive shows a Motor Over-load error, it indicates that the drive has exceeded its rated load during continuous operation. When the loading equals twice the rated loading, the alarm triggers within 10 seconds. Start by checking the connections for the motor terminals (U, V, W) and the encoder. Then, adjust the drive gain; incorrect gain settings can cause motor vibration and high current, leading to motor overload. Also, extend the acceleration/deceleration time or reduce the load ratio within the permitted range.

What to do if TECO JSDEP-50A Servo Drives show drive over-current?
- G
  Gary MillsAug 25, 2025
  If your TECO Servo Drive shows a Drive Over-current error, it indicates an over-current in the drive's main circuit or a transistor error. First, check the connections of the motor cable (U, V, W) and the encoder, as well as the power cable connection. If the problem persists, turn off the power and turn it on again after 30 minutes. If the alarm continues, there may be a power module malfunction or noise issues, requiring the drive to be tested and repaired.

How to fix position error in TECO JSDEP-50A Servo Drives?
- A
  Adam MartinezAug 26, 2025
  If your TECO Servo Drive displays a position error, it means the deviation between the pulse command and encoder feedback (position error) is greater than the setting of Pn308 or Pn309. To resolve this, first, increase the position loop gain (Pn310 and Pn311) setting value. Next, increase the position tolerance value using (Pn307) for improved motor response. Also, extend the acceleration/deceleration time or reduce load inertia within the permitted range. Finally, check if the motor wiring (U, V, W) is correct.

What causes motor over-current in TECO Servo Drives?
- S
  Shane RobertsonAug 28, 2025
  If your TECO Servo Drive shows a Motor over-current error, it indicates that the motor current is four times greater than the rated current. Check if the motor wiring (U, V, W) and encoder wiring are correct. Also, internal interference or malfunction could be the cause. Ensure that all connections are correct.

What to do if TECO JSDEP-50A Servo Drives show encoder ABZ phase signal error?
- J
  Jeremiah CunninghamAug 30, 2025
  If your TECO Servo Drive displays an Encoder ABZ phase signal error, it indicates a failure in the motor's encoder or a problem with the encoder connection. First, check the motor's encoder connections. Next, inspect the encoder for short circuits, poor solder joints, or breaks. Finally, check the encoder signal terminals CN2-1 and CN2-2 (power cable 5v).

How to resolve motor over speed in TECO Servo Drives?
- A
  Alexander StewartSep 1, 2025
  If your TECO Servo Drive shows a Motor over speed error, it means the motor’s speed is 1.5 times more than the motor’s rated speed. First, reduce the speed command. Second, check if the electronic gear ratio is incorrect and set it correctly. Finally, adjust speed loop gains (Sn211 & Sn213) for a better motor response.

What causes under-voltage in TECO JSDEP-50A Servo Drives?
- K
  kellyowensSep 3, 2025
  If your TECO Servo Drive displays an Under-voltage error, it means the main circuit voltage is below its minimum specified value (190Vac). Use a multimeter to check whether the input voltage is within the specified limit. If the problem persists, there may be a failure inside the drive.

What causes memory error in TECO JSDEP-50A Servo Drives?
- L
  Larry MasonSep 6, 2025
  If your TECO Servo Drive displays a Memory Error, it indicates a parameter write-in error. To solve this, disconnect all command cables and then recycle the power. If the alarm still occurs, it means the drive has failed.

Why does TECO JSDEP-50A Servo Drives show emergency stop error?
- N
  nicoleyoungSep 8, 2025
  If your TECO Servo Drive displays an Emergency Stop error, it means the input contact point EMC is activated, triggering Alarm 09. To resolve this, first, disable the Emergency stop signal input. If the issue persists, there may be an internal malfunction. Ensure that all connections are correct.
