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. Sets default of 1-23 Motor Frequency, to 50 Hz, shows 1-20 Motor Power in kW. Sets default of 1-23 Motor Frequency, to 60 Hz, shows 1-20 Motor Power in HP.
NOTICE

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.
NOTICE

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=0 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.

NOTICE
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.
NOTICE

The motor is only considered stopped when it is coasted.

Set-up

The Edit Set-up is for updating parameters in the frequency converter from either LCP 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. Update parameters in Set-up 1. Update parameters in Set-up 2. Update parameters in set-up selected as Active Set-up (see 0-10 Active Set-up).

0-12 Link Set-ups

Option:
[0] Not linked
[1 ] Linked *

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. Leaves parameters unchanged in both set-ups and cannot be changed while motor runs. Copy parameters “not changeable during operation” parameter values into presently selected Edit Set-up.
NOTICE

This parameter cannot be changed while motor runs.

4.4.3 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.

4.10 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].
