What to do if Emotron FDU DC Drives display 'PTC' error?
- E
  Eric MathisSep 4, 2025
  If your Emotron DC drive displays a 'PTC' error, it indicates that the motor thermistor (PTC) has exceeded its maximum level. This is only applicable if the PTC/PT100 option board is in use. Check for mechanical overload on the motor or machinery, inspect the motor cooling system, and ensure that a self-cooled motor isn't experiencing too high a load at low speed. You can also set PTC, menu [234] to OFF.

What causes 'Brake' error on Emotron FDU DC Drives and how to solve it?
- V
  valerie27Sep 18, 2025
  The 'Brake' error on Emotron DC Drives indicates that the brake tripped on a brake fault (not released) or the brake was not engaged during a stop. Check the brake acknowledge signal wiring to the selected digital input and the programming of digital input DigIn 1-8, [520]. Also, check the circuit breaker feeding the mechanical brake circuit, the mechanical brake itself if the acknowledge signal is wired from a brake limit switch, and the brake contactor. Finally, check settings [33C], [33D], [33E], and [33F].

What does 'LC Level' mean on Emotron FDU and how to troubleshoot it?
- D
  Donna CooperSep 14, 2025
  The 'LC Level' error on Emotron DC Drives indicates a low liquid cooling level in the external reservoir. This is only valid for AC drive types with a Liquid Cooling option. An external input (DigIn 1-8) might be active due to an active low function on the input. Check the liquid cooling system, the equipment and wiring initiating the external input, and the programming of the digital inputs DigIn 1-8.

What does 'Ext Mot Temp' mean on Emotron DC Drives and how to troubleshoot it?
- J
  Jeremy SmithSep 13, 2025
  The 'Ext Mot Temp' error on Emotron DC Drives indicates that an external input (DigIn 1-8) is active, likely due to an active low function on the input. To resolve this, check the equipment initiating the external input and verify the programming of the digital inputs DigIn 1-8.

What does 'PT100' error mean on Emotron DC Drives and how to resolve it?
- M
  Mallory WilliamsSep 9, 2025
  The 'PT100' error on Emotron DC Drives indicates that the motor PT100 elements have exceeded the maximum level. This is only applicable if the PTC/PT100 option board is used. Check for mechanical overload on the motor or machinery, inspect the motor cooling system, and ensure that a self-cooled motor isn't experiencing too high a load at low speed. You can also set PT100 to OFF in menu [234].

What does 'Encoder' error mean on Emotron DC Drives and how can I fix it?
- D
  David WhiteSep 8, 2025
  The 'Encoder' error on Emotron DC Drives suggests a problem with the encoder board, cable, or pulses, or a motor speed deviation between reference and measured speed. This is only valid if the Encoder option board is used. Check the encoder board, cable, and signals. Verify motor operation, speed deviation settings [22G#], speed PI controller settings [37#], and torque limit setting [351]. Alternatively, disable the encoder by setting menu [22B] to OFF.

What to do if Emotron DC Drives display 'Motor PTC' error?
- W
  William ForbesSep 6, 2025
  If your Emotron DC drive displays a 'Motor PTC' error, it indicates that the motor thermistor (PTC) has exceeded its maximum level. This is only applicable if [337] is enabled. Check for mechanical overload on the motor or machinery, inspect the motor cooling system, and ensure that a self-cooled motor isn't experiencing too high a load at low speed. You can also set PTC, menu [237] to OFF.

What to do if Emotron FDU show 'Over curr F'?
- C
  Christina ColemanAug 21, 2025
  If the Emotron DC drive shows an 'Over curr F' error, it means the motor current exceeds the drive's peak current. This can be due to several reasons: * Too short acceleration time. * Too high motor load. * Excessive load change. * Soft short-circuit between phases or phase to earth. * Poor or loose motor cable connections. * Too high IxR Compensation level. To resolve this, check the acceleration time settings and increase them if needed. Also, inspect the motor load, cable connections (including earth), and look for any moisture in the motor housing or cable connections. Finally, lower the level of IxR Compensation [352].
