CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
6.2.3 Commands The inverter has the following commands: PWM pulse enabling/
disabling, definition of the direction of rotation and JOG.
As the frequency reference, also the inverter commands can de
defined in several ways.
The main command sources are:
Via keypad key -key ;
Via control terminals (XC1) - digital inputs.
The inverter enabling and disabling commands can be defined as
follows:
Via keypad of the HMI;
Start/Stop (terminals XC1 - DI(s) - see P263 to P266);
General enable (terminals XC1 - DI(s) - see P263 to P266);
Forward and Reverse (terminals XC1 – DI’(s) - see P263 to P266)
– also defines the direction of rotation;
ON/OFF (3-wire controls) (terminals XC1 - DI’(s)- see P263
and P266).
The definition of the direction of rotation can be defined by using:
Digital input (DI) programmed for FWD/REV (see P263 to P266);
Digital inputs programmed as FWD / REV, that defines both
inverter enabling or disabling and direction of rotation (see P263
to P266);
Analog input - when thereference is via analog input and a negative
offset is programmed (P236 < 0), the reference may assume
negative values, thus reversing the direction of the motor rotation.
User can define two different conditions relating to the frequency
reference source and the inverter commands: these are the local and
the remote operation modes.
Figure 6.3 shows the local and remote operation modes in a block
diagram.
With the factory setting in local mode the inverter can be controlled by
using the keypad, (HMI) while in remote mode all controls are via
terminals (XC1) - inverter reference and command definition.
