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, 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] 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.
0-04 Operating State at Power-up (Hand Mode)
Option: Function:
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 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-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.
