Figure 2: SLC Event and Action

Events and actions are each numbered and linked in pairs (states), which means that when event [0] is fulfilled (attains the value TRUE),

action [0] is executed. After the 1st action is executed, the conditions of the next event are evaluated. If this event is evaluated as true,

then the corresponding action is executed. Only 1 event is evaluated at any time. If an event is evaluated as false, nothing happens in

the SLC during the current scan interval, and no other events are evaluated. When the SLC starts, it only evaluates event [0] during each

scan interval. Only when event [0] is evaluated as true, the SLC executes action [0] and starts evaluating the next event. It is possible to

program 1–20 events and actions. When the last event/action has been executed, the sequence starts over again from event [0]/action

[0]. The following illustration shows an example with 4 event/actions:

Comparators

Comparators are used for comparing continuous variables (output frequency, output current, analog input, and so on) to fixed preset

values.

What does 24 V supply low mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
- R
  Rhonda RoweSep 15, 2025
  If the 24 V supply is low in Danfoss DC Drives, the 24 V DC may be overloaded.

What does AMA check Unom and Inom mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
- N
  nmartinSep 15, 2025
  If you get an 'AMA check Unom and Inom' error with your Danfoss DC Drives, it indicates a wrong setting for motor voltage and/or motor current.

What does AMA low Inom mean in Danfoss VLT AutomationDrive FC 360 DC Drives?
- M
  morrisontiffanySep 15, 2025
  If you encounter an 'AMA low Inom' error on your Danfoss DC Drives, it means the motor current is too low. Check the settings.

What does 'Control word timeout' mean on my Danfoss Controller?
- A
  Anna OneillAug 30, 2025
  If the Danfoss Controller displays a 'Control word timeout' error, it means there is no communication to frequency converter.

Jonathon TrujilloAug 25, 2025
What to do if the Danfoss Controller displays a short circuit error?
- M
  Mackenzie SmithAug 25, 2025
  If the Danfoss Controller indicates a short circuit, it means there is a short circuit either in the motor or on the motor terminals. For J7 units, if this alarm occurs on power-up, check whether power cables are mistakenly connected to the motor terminals.

Joanna GarrettAug 25, 2025
What does it mean when my Danfoss Controller says 'Inverter overloaded'?
- M
  Makayla WhiteAug 26, 2025
  If the Danfoss Controller is indicating 'Inverter overloaded', it signifies that the load has exceeded 100% for an extended period.
A
Abigail GeorgeAug 26, 2025
What to do if my Danfoss Controller displays a 'Mains phase loss' error?
- A
  Angela StevensonAug 26, 2025
  If the Danfoss Controller shows a 'Mains phase loss' error, it means there is a missing phase on the supply side, or the voltage imbalance is too high. Check the supply voltage.
F

What does it mean when my Danfoss Controller displays a 'Torque limit' error?
- M
  Melanie RussellAug 26, 2025
  If the Danfoss Controller shows a 'Torque limit' error, it means the torque has exceeded the value set in either parameter 4-16 Torque Limit Motor Mode or parameter 4-17 Torque Limit Generator Mode.
J
Jack JohnsonAug 27, 2025
What does 'Brake overload' mean on my Danfoss Controller and how can I fix it?
- A
  Amy MurphyAug 27, 2025
  If the Danfoss Controller displays a 'Brake overload' error, it means that the power transmitted to the brake resistor over the last 120 seconds has exceeded the limit. To resolve this, try decreasing brake energy via lower speed or longer ramp time.
