0-02 Motor Speed Unit
Option:
Function:
This parameter cannot be adjusted while the motor is running.
The display showing depends on settings in par.0-02
. The default setting of par.0-02
depends on
which region of the world the frequency converter is supplied to, but can be re-programmed as
required.
NB!
Changing the
Motor Speed Unit
will reset certain parameters to their initial value.
It is recommended to select the motor speed unit first, before modifying other
parameters.
[0]
RPM
Selects display of motor speed variables and parameters (i.e. references, feedbacks and limits) in
terms of motor speed (RPM).
[1] *
Hz
Selects display of motor speed variables and parameters (i.e. references, feedbacks and limits) in
terms of output frequency to the motor (Hz).
0-03 Regional Settings
Option:
Function:
This parameter cannot be adjusted while the motor is running.
The display showing depends on settings in par.0-02
. The default setting of par.0-02
depends on
which region of the world the frequency converter is supplied to but can be re-programmed as
required.
[0] *
International
Sets par.1-20
units to [kW] and the default value of par.1-23
[50 Hz].
[1]
North America
Sets par.1-21
units to HP and the default value of par.1-23
to
60 Hz.
The setting not used is made invisible.
0-04 Operating State at Power-up
Option:
Function:
Select the operating mode upon reconnection of the frequency converter to mains voltage after
power down when operating in Hand (local)mode.
[0] *
Resume
Resumes operation of the frequency converter maintaining the same local reference and the same
start/stop condition (applied by [Hand On]/[Off] on the LCP or Hand Start via a digital input as
before the frequency converter was powered down.
[1]
Forced stop, ref=old
Uses saved reference [1] to stop the frequency converter but at the same time retain in memory
the local speed reference prior to power down. After mains voltage is reconnected and after re-
ceiving a start command (using the LCP [Hand On] button or Hand Start command via a digital
input) the frequency converter restarts and operates at the retained speed reference.
2.2.3 0-1* Set-up Operations
Define and control the individual parameter set-ups.
The frequency converter has four parameter setups that can be programmed independently of each other. This makes the frequency converter very
flexible and able to meet the requirements of many different AQUA system control schemes often saving the cost of external control equipment. For
example these can be used to program the frequency converter to operate according to one control scheme in one setup (e.g. daytime operation) and
another control scheme in another setup (e.g. night set back). Alternatively they can be used by an AHU or packaged unit OEM to identically program all
their factory fitted frequency converters for different equipment models within a range to have the same parameters and then during production/com-
missioning simply select a specific setup depending on which model within that range the frequency converter is installed on.
