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, par. 0-03, Regional Settings, is

implemented in the frequency converter. The selected setting influences the default setting of the motor nominal

frequency.

[0 ] International Sets default of par. 1-23, Motor Frequency, to 50 Hz, shows par. 1-20 in kW.

[1]

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

Option: Function:

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

NB!

This parameter cannot be adjusted while motor runs.

This parameter controls whether or not the frequency converter should start running the motor when powering up

after a power down in Hand mode.

NB!

If Keypad 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]

[2] Forced Stop, Ref=0 Frequency converter powers up in Off State meaning that motor is stopped after power up.

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.

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, Keypad, 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-up1 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 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.

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.

NB!

FactorySet-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

AF-60 LP™ Micro Drive Programming Guide

•the motor is coasted

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

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

NB!

The motor is only considered stopped when it is coasted.

[1 ]

[2] Set-up 2 Set-up 2 is active.

[9] Multi Set-up Select the active set-up via digital input and/or bus, see par. 5-1* choice [23].

Set-up 1 Set-up 1 is active.

0-11 Edit Set-up

Option: Function:

The Edit Set-up is for updating parameters in the frequency converter from either Keypad or bus. It can be identical

or different from the Active Set-up.

All set-ups can be edited during operation, independently of the active set-up.

[1 ]

[2] Set-up 2 Update parameters in Set-up 2.

[9] Active Set-up Update parameters in set-up selected as Active Set-up (see par. 0-10).

Set-up 1 Update parameters in Set-up 1.

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 linked Leaves parameters unchanged in both set-ups and cannot be changed while motor runs.

[1 ]

Linked Copy parameters “not changeable during operation” parameter values into presently selected Edit Set-up.

NB!

This parameter cannot be changed while motor runs.

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 resis-

tor, 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.

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, 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.

2-22 Activating Mechanical Brake

Range: Function:
