Programming Instructions A-1
A Programming
Instructions
The instructions in this appendix 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 later in this appendix.
A.1 Electrical connections
Before following the instructions in this chapter
ensure the Drive has been connected in accordance
with the instructions in Chapter 2 Installing the Drive,
in the Installation Guide or Chapter 2 Getting Started
in this User Guide.
When following the instructions in this appendix, It
is your responsibility to connect and disconnect the
AC supply as required.
Warning
The terminal cover must be
fitted to the Drive before the
AC supply is connected. If the
cover needs to be removed, the
AC supply must first be
disconnected for ten minutes.
Warning
The
AC supply must be
connected to the Drive with
appropriate fuses or
protection, as described in the
Installation Guide.
Warning
Adjustment of parameter
values must be performed only
by suitably trained or
experienced personnel.
Incorrect values could be
hazardous.
A.2 Preparation
1. Ensure that terminal 30 is connected to
terminal 31 or that a contact connected to
these terminals is closed.
2. If these instructions are being followed when a
macro other than Macro 1 is enabled, ensure
terminal 8 is connected to terminal 11 or a
motor thermistor is connected to these
terminals. These connections will allow the
Drive to be operated.
3. Ensure that terminals 27 and 28 are
open-circuit, or that contacts connected to
these terminals are open. This will prevent a
motor (if connected) from being driven.
4. Ensure that if a FREQUENCY potentiometer is
connected, it is set at minimum (wiper at
0V common).
5. Connect the
AC supply to the Drive.
6. The display is in Status mode and should indicate
as follows:
If the lower display shows triP and the upper
display shows one of the following, check the
cause and attend to the remedy:
Display Cause and remedy
th
Motor thermistor not connected, or terminal 8
not connected to terminal 11. Make the
necessary connections.
Et
External trip signal received, or terminal 30 not
connected to terminal 31. Make the necessary
connections.
rS
Motor is not connected, one phase is not
connected or the motor is open-circuit.
Press to reset the Drive. The display
should now show rdY
If the lower display still shows triP and another
code is shown on the upper display, see
Appendix E Diagnostics.
