Operation Modes
CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
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 mais 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 run;
It defines also the direction of rotation;
ON/OFF (3-wire controls) (terminals XC1 - DIs - see P263
and P264).
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 the reference is via analog input and a
negative offset is programmed (P236 or P240<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.
