4 Parameter Descriptions

4.1 Parameter Group 0: Operation/Display

0-03 Regional Settings

Option: Function:

In order to meet the needs for different default settings in different parts of the world, 0-03 Regional Settings, is implemented in the frequency converter. The selected setting influences the default setting of the motor nominal frequency.

[0 ] * Interna-

tional

Sets default of 1-23 Motor Frequency, to 50 Hz, shows 1-20 Motor Power in kW.

[1] US

Sets default of 1-23 Motor Frequency, to 60 Hz, shows 1-20 Motor Power in HP.

NOTE

This parameter cannot be changed while motor runs.

0-04 Operating State at Power-up (Hand Mode)

Option: Function:

This parameter controls whether or not the frequency converter start running the motor when powering up after a power down in Hand mode.

NOTE

If LCP with potentiometer is mounted, reference is set according to actual potentiometer value.

[0] Resume Frequency converter starts in same Hand or

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

[1] * Forced

Stop, Ref=Old

Frequency converter powers up in Off State meaning that motor is stopped after power up. Local reference is stored and used after power-up.

[2] Forced

Stop, Ref=0

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

•

Run motor in one set-up (Active Set-up) while updating parameters in another set-up (Edit Setup)

•

Connect various motors (one at a time) to frequency converter. Motor data for various motors can be placed in different set-ups.

•

Rapidly change settings of frequency converter and/or motor while motor is running (eg. ramp time or preset references) via bus or digital inputs.

The Active Set-up can be set as Multi Set-up where the active set-up is selected via input on a digital input terminal and/or via the bus control word.

NOTE

Factory Set-up cannot be used as Active Set-up.

0-10 Active Set-up

Option: Function:

Active Set-up controls the motor. Shifts between set-ups can only happen when

•

the motor is coasted

•

the set-ups between which the shift happens are linked to each other (see 0-12 Linked Set-ups).

If changing between set-ups that are not linked, the change will not happen before motor is coasted.

NOTE

The motor is only considered stopped when it is coasted.

0-12 Link Set-ups

Option: Function:

The link ensures synchronizing of the “not changeable during operation” parameter values enabling shift from one set-up to another during operation. If the set-ups are not linked, a change between them is not possible while the motor is running. Thus the set-up change does not occur until the motor is coasted.

[0] Not

4.2.7 1-9* Motor Temperature

With an estimated motor temperature monitor the frequency converter is able to estimate motor temperature without having a thermistor mounted. It is thus possible to receive a warning or an alarm, if motor temperature exceeds upper operational limit.

1-90 Motor Thermal Protection

Option: Function:

Using ETR (Electronic Terminal Relay) the motor temperature is calculated based on frequency, speed and time. Danfoss recommends using The ETR function, if a thermistor is not present.

NOTE

ETRElectronic Overload calculation is based on motor data from parameter group 1-2* Motor Data.

[0] * No Protection Disables temperature monitoring. [1] Thermistor

Warning

A thermistor connected to either digital or analog input gives a warning if upper limit of motor temperature range is exceeded, (see 1-93 Thermistor Resource).

DC braking current, set in 2-01 DC Brake Current, when ramping down. When set to 0 the function is off.

4.3.3 2-1* Brake Energy Function

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

2-10 Brake Function

Option: Function:

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.

NOTE

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

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.

[2] Enabled OVC is running, also when a stop signal is

active.

NOTE

If Resistor Brake has been chosen in 2-10 Brake Function the OVC is not active even though enabled in this parameter.

4.3.4 2-2* Mechanical Brake

For hoisting applications an electro-magnetic brake is required. The brake is controlled by a relay, which releases the brake when activated.

The brake activates if the frequency converter trips or a coast command is given. Furthermore, it activates when motor speed is ramped down below the speed set in 2-22 Active Brake Speed.

2-20 Release Brake Current

Range: Function:

0.00 A* [0.00-100 A] Select motor current at which mechanical

brake releases.

CAUTION

If start delay time has passed, and motor current is below Release brake current, frequency converter trips.

2-22 Activating Mechanical Brake

Range: Function:

If the motor is stopped using ramp, the mechanical brake is activated when motor speed is less than Active Brake Speed. Motor is ramped down to stop in the following situations:

•

A start command is removed (stand by)

•

A stop command is activated

•

4.4.4 3-4* Ramp 1

A linear ramp is characterized by ramping up at a constant speed until the desired motor speed has been reached. Some overshoot may be experienced when reaching speed, which may cause speed jerks for a short while before stabilizing. An S-ramp accelerates more smoothly thus compensating for jerks when the speed is reached.

4.6.1 5-** Digital In/Out

The following describes all digital input command functions and signals.

4.6.2 5-1* Digital Inputs

Parameters for configuring the functions for the input terminals. The digital inputs are used for selecting various functions in the frequency converter. All digital inputs can be set to the following:

[0] No Operation The frequency converter will not react to

signals transmitted to the terminal.

[1] Reset Reset the frequency converter after a Trip/

Alarm. Not all alarms can be reset.

[2 ] Coast Inverse Coasting stop, inverted input (NC). The

frequency converter leaves the motor in free mode.

[3] Coast and

reset inv.

Reset and coasting stop inverted input (NC). The frequency converter resets and leaves the motor in free mode.

[4] Quick stop

inverse

Inverted input (NC). Generates a stop in accordance with the quick-stop ramp time set in 3-81 Quick Stop Ramp Time. When motor stops, shaft is in free mode.

[5] DC-brake inv. Inverted input for DC braking (NC). Stops

motor by energizing it with DC current for a certain time period, see 2-01 DC Brake Current. Function is only active when value in 2-02 DC-Braking Time is different from 0.

[6] Stop inv. Stop inverted function. Generates stop

function when selected terminal goes from logical level “1” to “0”. Stop is performed according to selected ramp time.

[8] Start Select start for a start/stop command.

1 = Start, 0 = stop.

[9] Latched start Motor starts if a pulse is applied for min. 2

ms. Motor stops when Stop inverse is activated.

[10] Reversing Change direction of motor shaft rotation.

Reversing signal only changes direction of rotation; it does not activate start function. Select [2] Both directions in 4.10 Motor Speed Direction. 0 = normal, 1 = reversing.

[11] Start

reversing

Use for start/stop and for reversing at the same time. Signals on start [8] are not allowed at the same time. 0 = stop, 1 = start reversing.

[12] Enable start

4.10 Parameter Group 13: Smart Logic

4.10.1 13-** Programming Features

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].

5.1.1 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 5.6.

Example:

1-24 Motor Current has a conversion index of -2 (i.e. conversion factor of 0.01 according to Table 5.6). 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.

Conversion index Conversion factor 2 10 1 100 0 1

-1 0.1

-2 0.01

-3 0.001

-4 0.0001

-5 0.00001

Table 5.6 Conversion Table

5.1.2 Change during operation

“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.

5.1.3 2-Set-up

“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.

6 Troubleshooting

A warning or an alarm is signalled by the relevant LED on the front of the frequency converter and indicated by a code on the display.

A warning remains active until its cause is no longer present. Under certain circumstances operation of the motor may still be continued. Warning messages may be critical, but are not necessarily so.

In the event of an alarm, the frequency converter will have tripped. Alarms must be reset to restart operation once their cause has been rectified.

This may be done in four ways:

1. By pressing [Reset].

2. Via a digital input with the “Reset” function.

3. Via serial communication.

NOTE

After a manual reset press [Reset], [Auto On] or [Hand On] to restart the motor.

If an alarm cannot be reset, the reason may be that its cause has not been rectified, or the alarm is trip-locked (see also Table 6.1).

CAUTION

Alarms that are trip-locked offer additional protection, means that the mains supply must be switched off before the alarm can be reset. After being switched back on, the frequency converter is no longer blocked and may be reset as described above once the cause has been rectified. Alarms that are not trip-locked can also be reset using the automatic reset function in 14-20 Reset Mode (Warning: automatic wake-up is possible!) If a warning and alarm is marked against a code in the Table 6.1, this means that either a warning occurs before an alarm, or it can be specified whether it is a warning or an alarm that is to be displayed for a given fault. This is possible, for instance, in 1-90 Motor Thermal Protection. After an alarm or trip, the motor carries on coasting, and the alarm and warning flash on the frequency converter. Once the problem has been rectified, only the alarm continues flashing.

(X) Dependent on parameter

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 4, Mains phase loss A phase is missing on the supply side, or the mains voltage imbalance is too high. This message also appears for a fault in the input rectifier on the frequency converter.

Troubleshooting: Check the supply voltage and supply currents to the frequency converter. The fault may be caused by mains distortions. Installing Danfoss Line Filter may rectify this problem.

WARNING/ALARM 7, DC overvoltage If the intermediate circuit voltage exceeds the limit, the frequency converter trips after a time.

Troubleshooting

Connect a brake resistor Extend the ramp time Change the ramp type Activate the functions in 2-10 Brake Function Increase 14-26 Trip Delay at Inverter Fault

The fault may be caused by mains distortions. Installing Danfoss Line Filter may rectify this problem.

Troubleshooting

WARNING/ALARM 8, DC under voltage If the intermediate circuit voltage (DC link) drops below the under voltage limit, the frequency converter checks if a 24 V DC backup supply is connected. If no 24 V DC backup 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 input voltage test. Perform soft charge circuit test.

WARNING/ALARM 9, Inverter overload The frequency converter is about to cut out because of an overload (too high current for too long). 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%. The fault is that the frequency converter has run with more than 100% overload for too long.

Troubleshooting

Compare the output current shown on the LCP with the frequency converter rated current.

Compare the output current shown on the LCP with 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. Running AMT in 1-29 Automatic Motor Tuning

(AMT). The inverter peak current limit (approx. 200% of the rated current) is exceeded. The warning will last approx. 8-12 s, then the frequency converter trips and issues an alarm. Turn off the frequency converter and check if the motor shaft can be turned and if the motor size

matches the frequency converter. If extended mechanical brake control is selected, trip can be reset externally. may tune the frequency converter to the motor more accurately and reduce thermal loading.

WARNING/ALARM 11, Motor thermistor over temp The thermistor might be disconnected. Select whether the frequency converter gives a warning or an alarm in 1-90 Motor Thermal Protection.

Troubleshooting

Check for motor overheating. Check if the motor is mechanically overloaded.

WARNING/ALARM 13, Over current The inverter peak current limit (approx. 200% of the rated current) is exceeded. The warning will last approx. 8-12 s, then the frequency converter trips and issues an alarm. Turn off the frequency converter and check if the motor shaft can be turned and if the motor size matches the frequency converter. If extended mechanical brake control is selected, trip can be reset externally.

Troubleshooting:

Remove power and check if the motor shaft can be turned.

Check that the motor size matches the frequency converter.

Check parameters 1-20 through 1-25. for correct motor data.

ALARM 14, Earth (ground) fault There is current from the output phases to earth, either in the cable between the frequency converter and the motor or in the motor itself.

Troubleshooting:

Remove power to the frequency converter and repair the earth fault.

Check for earth faults in the motor by measuring the resistance to ground of the motor leads and the motor with a megohmmeter.

ALARM 16, Short circuit There is short-circuiting in the motor or motor wiring.

Remove power to the frequency converter and repair the short circuit.

WARNING/ALARM 17, Control word timeout There is no communication to the frequency converter. The warning is only active when 8-04 Control Word Timeout Function is NOT set to OFF. If 8-04 Control Word Timeout Function is set to Stop and Trip, a warning appears and the frequency converter ramps down until it trips, while giving an alarm. 8-03 Control Timeout Time could possibly be increased.

Troubleshooting:

Check connections on the serial communication cable.

Increase 8-03 Control Word Timeout Time Check the operation of the communication

equipment. Verify a proper installation based on EMC

requirements.

WARNING 25, Brake resistor short circuit 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 to the frequency converter and replace the brake resistor (see 2-15 Brake Check).

WARNING/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. Remove power to the frequency converter and remove the brake resistor.

WARNING/ALARM 28, Brake check failed The brake resistor is not connected or not working.

ALARM 29, Heatsink temp The maximum temperature of the heatsink has been exceeded. The temperature fault will not reset until the temperature falls below a defined heatsink 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 cable too long. Incorrect airflow clearance above and below the

frequency converter. Blocked airflow around the frequency converter. Damaged heatsink fan. Dirty heatsink.

ALARM 30, Motor phase U missing Motor phase U between the frequency converter and the motor is missing.

Remove 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.

Remove 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.

Remove 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.

WARNING 47, 24 V supply low The 24 V DC is measured on the control card. The external 24 V DC backup power supply may be overloaded, otherwise contact the Danfoss supplier.

ALARM 51, AMT check U

nom

and I

nom

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. Reset the unit to clear the alarm.

ALARM 84,The connection between drive and LCP is lost Try to reassemble the LCP gently.

ALARM 85, Button disabled See parameter group 0-4* LCP

ALARM 86, Copy fail An error occurred while copying from frequency converter to LCP or vice versa.

ALARM 87, LCP data invalid Occurs when copying from LCP if the LCP contains erroneous data - or if no data was uploaded to the LCP.

ALARM 88,LCP data not compatible Occurs when copying from LCP if data are moved between frequency converters with major differences in software versions.

WARNING 89, Parameter read only Occurs when trying to write to a read-only parameter.

ALARM 90, Parameter database busy LCP and RS-485 connection are trying to update parameters simultaneously.
