Off State as when powered off. Local reference is stored and used after power-up.

[1] * Forced

Stop, Ref=Old

[2] Forced

Stop, Ref=0

Frequency converter powers up in Off State meaning that motor is stopped after power up. Local reference is stored and used after power-up. Frequency converter powers up in Off State meaning that motor is stopped after power up. Local reference is set to 0. Thus motor will not start running before local reference has been increased.

4.1.1 0-1* Set-up Handling

User-defined parameters and miscellaneous external inputs (eg. bus, LCP, analog/digital inputs, feedback, etc.) controls the functionality of the frequency converter.

A complete set of all parameters controlling the frequency converter is called a set-up. The frequency converter contains 2 set-ups, Set-up 1 and Set-up 2. Furthermore, a fixed set of factory settings can be copied into one or more set-ups.

Some of the advantages of having more than one set-up in the frequency converter are

Use the parameters in this group for selecting dynamic braking parameters.

2-10 Brake Function

Option: Function:

NOTICE

Resistor brake is only functional in frequency converters with integrated dynamic brake. An external resistor must be connected.

Resistor brake

The resistor brake limits voltage in the intermediate circuit when the motor acts as generator. Without brake resistor, the frequency converter eventually trips. The resistor brake consumes surplus energy resulting from motor braking. A frequency converter with brake, stops a motor faster than without a brake, which is used in many applications. Requires connection of external brake resistor. An alternative to the resistor brake is the AC brake.

AC brake

The AC brake consumes surplus energy by creating power loss in the motor. It is important to keep in mind that an increase in power loss causes motor temperature to rise.

4.10 Parameter Group 13: Smart Logic

Smart Logic Control (SLC)is a sequence of user-defined actions (13-52 SL Controller Action [X]) executed by the SLC when the associated user-defined event (13-51 SL Controller Event [X]) is set to True.

Events and actions are linked in pairs, meaning that when an event is true, the linked action is carried out. After this the next event is evaluated and its belonging action carried out and so on. Only one event is evaluated at the time.

If an event is evaluated as False, the SLC takes no action during the scan interval and no other events are evaluated.

It is possible to programme from 1 to 20 events and actions. When the last event/action has been executed, the sequence starts again from event/action [0].

Illustration 4.10 Example with Three Events/Actions

Starting and stopping the SLC

Start the SLC by selecting [1] On in 13-00 SL Controller Mode The SLC starts evaluating Event 0, and if this is

evaluated as TRUE, the SLC continues its cycle. The SLC stops when the Stop Event, 13-02 Stop Event, is

TRUE. The SLC can also be stopped by selecting [0] Off in 13-00 SL Controller Mode.

To reset all SLC parameters select [1] Reset SLC in 13-03 Reset Smart Logic Controller and start programming from scratch.

5.2.1 Conversion Index

The various attributes of each parameter are displayed in the section Factory Settings. Parameter values are transferred as whole numbers only. Conversion factors are therefore used to transfer decimals according to Table 5.1.

Example: 1-24 Motor Current has a conversion index of -2 (i.e. conversion factor of 0.01 according to Table 5.1). To set the

parameter to 2.25 A, transfer the value 225 via Modbus. The Conversion Factor of 0.01 means that the value transferred is multiplied by 0.01 in the frequency converter. The vale 225 transferred on the bus is thus perceived as

2.25 A in the frequency converter.

TRUE means that the parameter can be changed while the frequency converter is in operation and FALSE means that the frequency converter must be stopped before a change can be made.

2-Set-up

5.2.3

All set-up: The parameter can be set individually in each of the two set-ups, i.e. one single parameter can have two different data values. 1 set-up: Data value will be the same in both set-ups.

A trip is the action when an alarm has appeared. The trip will coast the motor and can be reset by pressing [Reset] or make a reset by a digital input (parameter group 5-1* [1]). The original event that caused an alarm cannot damage the frequency converter or cause dangerous conditions. A trip lock is an action when an alarm occurs, which may cause damage to frequency converter or connected parts. A trip lock situation can only be reset by a power cycling.

WARNING/ALARM 8, DC under voltage

If the DC link voltage drops below the undervoltage limit, the frequency converter checks if a 24 V DC back-up supply is connected. If no 24 V DC back-up supply is connected, the frequency converter trips after a fixed time delay. The time delay varies with unit size.

Troubleshooting

Check that the supply voltage matches the

•

frequency converter voltage.

Perform an input voltage test.

•

Perform a soft charge circuit test.

•

WARNING/ALARM 9, Inverter overload

The frequency converter has run with more than 100% overload for too long and is about to cut out. The counter for electronic thermal inverter protection issues a warning at 98% and trips at 100%, while giving an alarm. The frequency converter cannot be reset until the counter is below 90%.

Troubleshooting

Compare the output current shown on the LCP

•

with the frequency converter rated current.

Compare the output current shown on the LCP

•

with the measured motor current.

Display the thermal drive load on the LCP and

•

monitor the value. When running above the

frequency converter continuous current rating,

the counter increases. When running below the

frequency converter continuous current rating,

the counter decreases.

WARNING/ALARM 10, Motor overload temperature

According to the electronic thermal protection (ETR), the motor is too hot. Select whether the frequency converter gives a warning or an alarm when the counter reaches 100% in 1-90 Motor Thermal Protection. The fault occurs when the motor is overloaded by more than 100% for too long.

Troubleshooting

Check for motor overheating.

Check if the motor is mechanically overloaded

Check that the motor current set in 1-24 Motor

Current is correct.

Ensure that motor data in parameters 1-20

through 1-25 are set correctly.

The brake resistor is monitored during operation. If a short circuit occurs, the brake function is disabled and the warning appears. The frequency converter is still operational but without the brake function. Remove power

from the frequency converter and replace the brake resistor (see 2-15 Brake Check).

ALARM 27, Brake chopper fault

The brake transistor is monitored during operation, and if a short circuit occurs, the brake function is disabled and a warning is issued. The frequency converter is still operational but, since the brake transistor has shortcircuited, substantial power is transmitted to the brake resistor, even if it is inactive.

Troubleshooting

Remove power to the frequency converter and

•

remove the brake resistor.

ALARM 28, Brake check failed

The brake resistor is not connected or not working.

ALARM 29, Heat Sink temp

The maximum temperature of the heat sink has been exceeded. The temperature fault does not reset until the temperature drops below a defined heat sink temperature. The trip and reset points are different based on the frequency converter power size.

Troubleshooting

Check for the following conditions:

Ambient temperature too high.

•

Motor cables too long.

•

Incorrect airflow clearance above and below the

•

frequency converter.

Blocked airflow around the frequency converter.

•

Damaged heat sink fan.

•

Dirty heat sink.

•

ALARM 30, Motor phase U missing

Motor phase U between the frequency converter and the motor is missing.

Troubleshooting

Remove the power from the frequency converter

•

and check motor phase U.

ALARM 31, Motor phase V missing

Motor phase V between the frequency converter and the motor is missing.

Troubleshooting

Remove the power from the frequency converter

•

and check motor phase V.

ALARM 32, Motor phase W missing

Motor phase W between the frequency converter and the motor is missing.

Troubleshooting

Remove the power from the frequency converter

•

and check motor phase W.

ALARM 38, Internal fault

Troubleshooting

Cycle power.

•

Check that the option is properly installed.

•

Check for loose or missing wiring.

•

It may be necessary to contact the local Danfoss supplier or service department. Note the code number for further troubleshooting directions.

ALARM 46, Gate drive voltage fault

The supply on the power card is out of range. There are 3 power supplies generated by the switch mode

power supply (SMPS) on the power card: 24 V, 5 V, and ±18 V.

Troubleshooting

Check for a defective power card.

•

ALARM 51, AMT check U

The settings for motor voltage, motor current, and motor power are wrong. Check the settings in parameters 1-20 to 1-25.

ALARM 55, AMA parameter out of range

The parameter values of the motor are outside of the acceptable range. AMA does not run.

ALARM 63, Mechanical brake low

The actual motor current has not exceeded the release brake current within the start delay time window.

ALARM 80, Drive initialised to default value

Parameter settings are initialised to default settings after a manual reset. To clear the alarm, reset the unit.

ERROR 84,The connection between drive and LCP is lost

Try to reassemble the LCP gently.

ERROR 85, Button disabled

See parameter group 0-4* LCP

ERROR 86, Copy fail

An error occurred while copying from frequency converter to LCP or vice versa.

ERROR 87, LCP data invalid

Occurs when copying from LCP if the LCP contains erroneous data - or if no data was uploaded to the LCP.

ERROR 88,LCP data not compatible

Occurs when copying from LCP if data are moved between frequency converters with major differences in software versions.

ERROR 89, Parameter read only

Occurs when trying to write to a read-only parameter.

ERROR 90, Parameter database busy

LCP and RS-485 connection are trying to update parameters simultaneously.

ERROR 91, Parameter value is not valid in this mode

Occurs when trying to write an illegal value to a parameter.

ERROR 92, Parameter value exceeds the min/max limits

Occurs when trying to set a value outside the range. Parameter can only be changed when the motor is stopped. Err. A wrong password was entered, occurs when using a wrong password for changing a passwordprotected parameter.
