THE KEYPAD
The keypad comprises membrane-type keys
as well as an integral 4-digit 7-segment LED
display. The keys are limited to [run], [stop],
[up], [down] and [P]. All parameters can be
accessed and changed using the keys.
PARAMETER TYPES
There are three types of parameter:
1 True value parameters. For example,
setting parameter P003 to 10 seconds tells
the Eco to take 10 seconds to slow the
motor from its normal operating speed to
stopped (ramp-down time).
2 Limited range parameters. The values
themselves are not relevant and only represent
the function required. For example, parameter
P199 can only be set to 0 to 1. Setting the value
to 0 tells the Eco to give access to the basic
parameters only. Setting the value to 1 gives
access to the expert parameters.
3 ‘Read only’ parameters. The values of
these parameters are factory set and
provide the user with information. For
instance, parameter P111 is a read only
parameter and indicates the inverter’s
variable torque power rating in kW.
PARAMETER RANGES
The Eco has three ranges of parameters;
Display mode, Basic mode and Expert mode.
One of the Basic mode parameters (P199)
controls access to the Expert mode
parameters. The Basic mode parameters are
described in this section. A list of the Expert
mode parameters is contained in the next
section. For further information on using
Expert mode, refer to the Reference Manual.
ACCESSING PARAMETERS
AND CHANGING VALUES
The and keys are used to change
parameter values. The keys have two modes
of operation. A single momentary press will
change the value by a value of 1. Keeping the
button pressed for longer initiates scrolling and
allows values to be changed rapidly.
To access a parameter and change its value,
follow the simple sequence described below:
Key Action Display
P
Press P to enter parameter
mode
Use the [up] and [down] keys to
select the required parameter
number (e.g. ramp-up time)
P
Press P to confirm that you
wish to enter a value for that
parameter. The current value
is displayed
Use the [up] and [down] keys
to enter the required value
P
Press P to confirm that you have
changed the value as required.
The parameter number is re-
displayed.
Use the [up] and [down] keys
to return the parameter
number to the display default
parameter.
P
Press P to return to default display
The display will alternate between the setpoint
frequency and actual output frequency, which
will be 0 Hz.
