Variant Independent Options

For more details of the following options, please refer to the CD-ROM supplied with
the inverter.
4.3.1

Basic Operator Panel (BOP)

The BOP can be used for setting individual parameters. Values and units are
shown on a clear 5-digit display. It may be used for several inverters. Please see
Appendix A in the Operating Instructions for the method of changing the Operator
panel.
The BOP may be directly mounted on the inverter or on a cabinet door using a
suitable mounting kit. (See paragraph 4.3.6. on Page 74)
4.3.2

Advanced Operating Panel (AOP)

The Advanced Operator Panel (AOP) enhances the interface/communication
capability of the MICROMASTER range of frequency inverters. Available in either
Inverter, Desk or Panel mounted form. The unit provides the user with an
intelligent, clear text inverter interface. This gives direct access to the control,
programming, storage and monitoring of MICROMASTER series operating
parameters.
For local control of individual inverters the AOP is mounted directly onto the
inverter fascia. Alternatively the unit can operate remote from the inverter (single
or multi-drop) within either a Desk or Panel mounted support platform. When used
as the master inverter on a dedicated system bus (multi-drop) the AOP has the
capacity to communicate with up to 31 inverters. Each inverter is allocated a slave
address and full operator control is possible throughout. In this mode the AOP can
be used as a PC management tool to permit network control with 'SIMOVIS'
software.
Each unit supports software capable of carrying out configuration and storage of
inverter parameter sets. Software menus, inverter parameters, associated values
and help text is displayed on a compact dot matrix LCD screen. Operator
commands for software are derived from a keypad located directly below the LCD
screen. Communication with dependent inverters in single or multi-drop
configuration is achieved via RS232 or RS485 interface terminals.
The clear text operating panel consists of a control and display unit that fits directly
on top of the MICROMASTER 420. A D-Type socket connects directly onto the D-
type on the front of the unit, so the AOP can take power from and communicate
with the inverter via the RS485 interface. The AOP offers the following features:
The AOP has several practical uses. For example:
•
The AOP may be mounted directly onto the inverter and used to control the
inverter directly.
•
The AOP can be mounted on a separate panel (using an optional cable of
up to 5 m) to enable remote control and monitoring of the inverter.
•
If an external power supply is connected to the AOP, remote control over
distances greater than 5 m is permissible.
•
The built in RS232 to RS485 connector can be used to allow
communication between a PC and the inverter.
•
Parameter sets can be stored in the AOP and uploaded or downloaded as
required. This is particularly useful where many inverters require
programming in production.
