VLTp Micro Drive FC 51 1. Safety

1. Safety

1.1.1. High Voltage Warning

The voltage of the frequency converter is dangerous whenever it is connected to mains. Incorrect installation of the motor or frequency

converter may cause damage to the equipment, serious injury or death. Consequently, it is essential to comply with the instructions

in this manual as well as local and national rules and safety regulations.

1.1.2. Safety Instructions

• Make sure the frequency converter is properly connected to earth.

• Do not remove mains connections, motor connections or other power connections while the frequency converter is connected to power.

• Protect users against supply voltage.

• Protect the motor against overloading according to national and local regulations.

• The earth leakage current exceeds 3.5 mA.

• The [OFF] key is not a safety switch. It does not disconnect the frequency converter from mains.

1.1.3. Software Version and Approvals

Software Version

Programming Guide

VLT Micro Drive

FC 51 Series

This Programming Guide can be used for all VLT Micro Drive frequency drives with software version

2.1x.

The software version number can be read in

parameter 15-43.

1.1.4. General Warning

Warning:

Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.

Also make sure that other voltage inputs have been disconnected (linkage of DC intermediate circuit).

Be aware that there may be high voltage on the DC link even when the LEDs are turned off.

Before touching any potentially live parts of the frequency converter, wait at least 4 minutes for all sizes.

Shorter time is allowed only if indicated on the nameplate for the specific unit.

MG.02.C4.02 - VLTp is a registered Danfoss trademark

1. Safety VLTp Micro Drive FC 51

Leakage Current

The earth leakage current from the frequency converter exceeds 3.5 mA. According to IEC 61800-5-1 a reinforced Protective Earth

connection must be ensured by means of a min. 10mm² Cu or an addtional PE wire - with the same cable cross section as the Mains

wiring - must be terminated separately.

Residual Current Device

This product can cause a DC current in the protective conductor. Where a residual current device (RCD) is used for extra protection,

only an RCD of Type B (time delayed) shall be used on the supply side of this product. See also Danfoss Application Note on RCD, MN.

90.GX.YY.

Protective earthing of the frequency converter and the use of RCDs must always follow national and local regulations.

Motor overload protection is possible by setting Parameter 1-90 Motor thermal protection to the value ETR trip. For the North American

market: ETR functions provide class 20 motor overload protection, in accordance with NEC.

Installation in high altitudes:

For altitudes above 2 km, please contact Danfoss regarding PELV.

1.1.5. IT Mains

IT Mains

Installation on isolated mains source, i.e. IT mains.

Max. supply voltage allowed when connected to mains: 440 V.

As an option, Danfoss offers line filters for improved harmonics performance.

1.1.6. Avoid unintended Start

While the frequency converter is connected to mains, the motor can be started/stopped using digital commands, bus commands, references or via the

Local Control Panel.

• Disconnect the frequency converter from mains whenever personal safety considerations make it necessary to avoid unintended start of any

motors.

• To avoid unintended start, always activate the [OFF] key before changing parameters.

1.1.7. Disposal Instruction

Equipment containing electrical components must not be disposed of together with domestic waste.

It must be separately collected with electrical and electronic waste according to local and currently valid leg-

islation.

1.1.8. Before Commencing Repair Work

1. Disconnect FC 51 from mains (and external DC supply, if present.)

2. Wait for 4 minutes for discharge of the DC-link.

3. Disconnect DC bus terminals and brake terminals (if present)

4. Remove motor cable

3. Programming

3.1. How to Programme

3.1.1. Programming with MCT-10 Set-up Software

The frequency converter can be programmed from a PC via RS485 com-port by installing the MCT-10 Set-up Software.

This software can either be ordered using code number 130B1000 or downloaded from the Danfoss Web site: www.danfoss.com, Business Area: Motion

Controls.

Please refer to manual MG.10.RX.YY.

3.1.2. Programming with the LCP 11 or LCP 12

The LCP is divided into four functional groups:

1. Numeric display.

2. Menu key.

3. Navigation keys.

4. Operation keys and indicator lights (LEDs).

Illustration 3.1: LCP 12 with potentiometer

The display:

A number of information can be read from the display.

Set-up number shows the active set-up and the edit set-up. If the same

set-up acts as both active and edit set-up, only that set-up number is

shown (factory setting).

When active and edit set-up differ, both numbers are shown in the display

(Setup 12). The number flashing, indicates the edit set-up.

Local reference is stored and used 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.

Set-up1

and

A complete set of all parameters controlling the frequency converter is called a set-up. The frequency converter contains 2 set-ups,

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 Set-up)

• 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.

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.

NB!

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.

[1] Resistor Brake Resistor brake is active.

[2] AC Brake AC brake is active.

Off No brake function.

100.0 %* [0.0 - 150.0 %]

Enter max. permissible current for AC-braking to avoid overheating of motor.

100% equals motor current set in par. 1-24.

2-17 Over-Voltage Control

Option: Function:

Use Over-voltage Control (OVC) to reduce the risk of the frequency converter tripping due to an over voltage

on the DC link caused by generative power from the load.

An over-voltage occurs eg. if the ramp down time is set too short compared to the actual load inertia.

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 frequency converter trips or a coast command is given. Furthermore, it activates when motor speed is ramped down below the

speed set in par. 2-22,
