What to do if Control Techniques Epsilon EP-I shows 'Overspeed' fault?
If the Control Techniques Control Unit displays an 'Overspeed' fault, it means the actual motor speed has exceeded the Overspeed Velocity Limit parameter. To resolve this, use the Reset Button or Input Line.
What to do if Control Techniques Epsilon EP-I shows 'High DC Bus' fault?
This fault occurs whenever the voltage on the DC bus exceeds 440 Vdc. To resolve this, use the Reset Button or Input Line.
What to do if Control Techniques Control Unit displays 'Motor Overtemp'?
This fault appears when the motor thermal switch is open due to motor over-temperature or incorrect wiring. To fix this, allow the motor to cool down and then use the Reset Button or Input Line.
What to do if Control Techniques Epsilon EP-I Control Unit shows 'Low DC Bus' fault?
This fault will occur whenever the voltage on the DC bus drops below 60 volts. To resolve this, use the Reset Button or Input Line.
What to do if Control Techniques Epsilon EP-I Control Unit displays 'Max Following Error'?
This fault is generated when the following error exceeds the following error limit (default following error limit is 0.2 revs). To resolve this, change the Following Error Limit value or disable it on the Position view.
What does 'Power Module' fault mean on a Control Techniques Epsilon EP-I, and how to fix it?
The 'Power Module' fault on a Control Techniques Control Unit indicates a power stage over-temperature, over-current, or loss of power stage logic supply. To resolve this, use the Reset Button or Input Line, or Cycle Logic Power (MDS).
What to do if Control Techniques Control Unit displays 'Invalid Configuration'?
The FM was not on this drive during its previous power-up and it is not known if the setup data in the FM matches the drive and motor to which the FM is now attached. To resolve this, create or open a configuration file with the correct drive and motor selections and download the configuration to the FM or drive. This can also happen when a FM is removed from a drive and the drive is powered-up. To resolve this, press and hold the drive’s Reset button for 10 seconds (until the fault is cleared).
Why does my Control Techniques Epsilon EP-I show 'Drive Overtemp'?
The 'Drive Overtemp' fault (Epsilon drive only) on your Control Techniques Control Unit indicates that the drive IGBT temperature has reached 100ºC (212ºF). To resolve this, allow the drive to cool down, then cycle power or cycle logic power.
What does 'NVM Invalid' mean on Control Techniques Control Unit and how to solve it?
If your Control Techniques Control Unit displays 'NVM Invalid', it means that at power-up, the drive detected invalid contents in the non-volatile memory. To solve this, use the Reset Button or Input Line.
What does 'Encoder State' mean on Control Techniques Epsilon EP-I and how can I fix it?
If your Control Techniques Control Unit displays 'Encoder State', it means certain encoder states and state transitions are invalid. To fix this, cycle power or cycle logic power.
