Procedures for displaying, changing
and saving a parameter value
The following instructions take you step-by-step through learning how to
use the display and keypad, and alert you to avoid actions that could cause
confusion. It is in your interests to follow these instructions carefully.
The instructions can be used when the Drive is operating in Keypad or
Terminal mode. They cover the basic procedure for accessing a numerical
variable parameter. Instructions for accessing other types of parameter, as
well as for more advanced operations, are given in
Variations in operation
later in this chapter.
Warning
It is strongly recommended that a motor is not connected to
the Drive while you learn how to use the display and keypad.
Bit parameters can be adjusted when the Drive is running.
Some bit parameters are used to make extensive changes to
the configuration of the Drive. Before adjusting a bit
parameter, make sure that it is safe to do so.
Preparation
1
Ensure that terminals B4 and B5 are connected to terminal B1
(0V common), or that contacts connected to these terminals are
closed. This will allow the Drive to be operated.
2
Ensure that terminals B2 and B3 are open-circuit, or that contacts
connected to these terminals are open. This will prevent a motor
(if connected) from being driven.
3
Ensure that if a
SPEED
potentiometer is connected, it is set at minimum
(wiper at 0V common).
4
Connect the
AC
supply to the Drive.
The display should show
rdY
(as shown in Figure 5–1). The display is in
Status mode
.
If the display shows either of the following instead of
rdY
, check the
connection to the terminal indicated:
