0-02 Motor Speed Unit
3 3
Option: Function:
The display showing depends on settings in
0-02 Motor Speed Unit and 0-03 Regional Settings. The
default setting of 0-02 Motor Speed Unit and
0-03 Regional Settings depends on which region of
the world the frequency converter is supplied to, but
can be re-programmed as required.
NOTE
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).
NOTE
This parameter cannot be adjusted while the motor is
running.

The display showing depends on settings in
0-02 Motor Speed Unit and 0-03 Regional
Settings. The default setting of 0-02 Motor Speed
Unit and 0-03 Regional Settings depends on
which region of the world the frequency
converter is supplied to but can be re-
programmed as required.
Sets 1-20 Motor Power [kW] units to [kW] and
the default value of 1-23 Motor Frequency [50
Hz].
Sets 1-21 Motor Power [HP] units to HP and the
default value of 1-23 Motor Frequency to 60 Hz.
Function:
Select the operating mode upon reconnection
of the frequency converter to mains voltage
after power down when operating in Hand
(local) mode.

3.2.1 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 VLT Refrigeration
Drive 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/commissioning
simply select a specific setup depending on which model
within that range the frequency converter is installed on.
The active setup (i.e. the setup in which the frequency
converter is currently operating) can be selected in
parameter 0-10 and is displayed in the LCP. Using Multi
set-up it is possible to switch between set-ups with the
frequency converter running or stopped, via digital input
or serial communication commands (e.g. for night set
back). If it is necessary to change setups whilst running,
ensure 0-12 This Set-up Linked to is programmed as
required. For the majority of VLT Refrigeration Drive
applications it will not be necessary to program 0-12 This

Function:
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.
Uses [1] Forced stop, ref=old 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 receiving a start
command (pressing [Hand On] or Hand Start
command via a digital input) the frequency
converter restarts and operates at the retained
speed reference.
Function:
Defines if the local reference unit should
be displayed in terms of the motor shaft
speed (in RPM/Hz) or as percent.
