CHAPTER 6 - DETAILED PARAMETER DESCRIPTION
6.2.5
Commands
6.2.6
Local/Remote
Operation Modes
The inverter has the followingcommands:PWMpulseenabling/
disabling, definition of the direction of rotation and JOG.
As the frequency reference, the inverter commands can de
defined in several ways.
The command sources are the following:
Via keypad - keys , , and .
Via control terminals (XC1) - digital inputs.
Via serial interface.
The inverterenabling and disablingcommands canbe defined
as follows:
Via keypad and of the HMI.
Via serial.
Start/stop (terminals XC1 - DI(s) - refer to the parameter
P263 to P266).
General enable (terminals XC1 - DI(s) - refer to the
parameter P263 to P266).
Forward run (terminals XC1 - DI(s) - refer to the parameter
P263 and P264), it also defines the diretion of rotation.
ON/OFF (3-wire control) (terminals XC1 - DIs - refer to the
parameters P263 and P264).
The definition of the direction of rotation can be defined by
using:
The key of the keypad.
Serial.
Digital input
(DI) program
med for FWD/REV
(
refer to the
parameter
P264 to P266)
.
Digital inputs programmed as FWD / REV, that defines both
Inverterenabling or disabling and direction of rotation (refer
to the parameters
P263 and P264).
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
frequencyreferencesourceand 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, while in remote mode all
controls are via terminals (XC1) - reference definition and
inverter commands.
