Control Interface Option – TB3
The Control Interface Option provides a means of interfacing various
signals and commands to the 1336 FORCE by using contact closures.
Six different versions of the option are available:
L4 Contact Closure Interface
L4E Contact Closure Interface with Encoder Feedback Inputs
1
L5 +24V AC/DC Interface
L5E +24V AC/DC Interface with Encoder Feedback Inputs
1
L6 115V AC Interface
L6E 115V AC Interface with Encoder Feedback Inputs
1
1
Encoder feedback inputs are connected to TB10 on the FORCE Drive. Do Not
connect Encoder Feedback inputs to the Control Interface Option card.
The user inputs are connected to the option board through TB3. The L4, L5
and L6 options each have nine control inputs. The function of each input
must be selected through programming as explained later in this section.
The L4E, L5E and L6E options are similar to L4, L5 and L6 with the
addition of encoder feedback inputs, which are not used with the 1336
FORCE.
Available Inputs
A variety of combinations made up of the following inputs are available.
Start Enable
Stop/Clear Fault Ext Flt
Reverse 2 Stop Mode Selects
Digital Potentiometer (MOP) Run Forward
2 Accel/Decel Rates Run Reverse
3 Speed Selects Local Control
The available combinations are shown in Figure 2.24. Programming the
[Input Mode] parameter to one of the Input Mode numbers listed, will
select that combination of input functions.
Important: The [Input Mode] parameter can be changed at any time, but
the change will not affect drive operation until power to the drive has been
removed and bus voltage has decayed completely. When changing the
[Input Mode] parameter, the functions of the TB3 inputs will change when
power is reapplied to the drive.
Important: If a Control Interface Option is not installed, the [Input Mode]
parameter must be set to 1 (default) and jumpers must be installed. If the
drive was shipped from the factory without the option, these jumpers will
have been installed.
The programming options of the Control Interface Option allow the user to
select an input combination to meet the needs of a specific installation.
Appropriate selection of a combination may be done by using Figure 2.24.
First determine the type of start/stop/direction control desired. Then select
the remaining control functions available. Record the selected mode
number below.
