Control connections and configuration

General

The purpose of selecting particular control connections and setting various configuration parameters is
to select the required logical and speed control functions for the particular application. The configurable
items can be grouped as follows:
Category Description
Display Customisation of the display in terms of what variable (speed, frequency, load,
current, voltage etc) is displayed. Customisation of the output frequency display to
show user defined units. Some housekeeping functions.
Motor Information from the motor nameplate.
Performance Maximum and minimum speeds, acceleration rates, motor flux adjustment etc.
Protection Current limit settings, I2t (thermal overload) etc.
Stop / Start Choices for stopping, automatic restart options etc.
References Choice of speed signal source to be used in local and remote modes, jog speeds.
Input / Output Assignment of particular control functions to terminals (inputs) and relays (status
outputs). These can be selected individually.
The MSC-3 control terminals can be configured, on an individual terminal basis, to suit a wide variety of
applications. This provides enormous flexibility.

Factory default settings

The factory default terminal configuration provides for single direction control from either the terminal
strip or the front panel console, as selected by a local / remote input on the terminal strip. This is
detailed as "Config 1", starting on page 20.
There is a menu function to restore the terminal configuration and all parameters to the factory default
state should you wish to do so. See Load Factory Defaults.

Settings for your application

The function of each of the analogue inputs, digital inputs and status relays may be individually assigned
from an extensive list. in addition, digital inputs may be assigned to be level or edge sensitive and there
are additional internal functions including timers that are fully configurable. Many applications may be
easily configured using one of the quick setup applications listed below.

Quick Setup

To assist with quick configuration of the most frequently encountered applications, there are a number of
application specific setup guide pages in this manual. Terminal strip configuration and associated setup
notes are provided on the pages listed below.
