Figure 8-22 Interconnection for "Enable operation"
You must make sure that the converter only enables the pulses when the breaker is closed.
This is achieved using the specified interconnection.
To activate the interconnection, parameterization (in the expert list) must be carried out as
follows (in this example, it has been assumed that the drive is called "Drive_1" in the project
navigator):
● (Drive_1) p20032 = 0
● (Drive_1) p20030[0] = (TM31) r4022.9
● (Drive_1) p20030[1] = (Drive_1) r0863.1
● (Drive_1) p20030[2] = 1
● (Drive_1) p20030[3] = 1
● (Drive_1) p0860 = (Drive_1) r20031

The "AND 0" function block is assigned to the run-time group 0.
The TM31 digital input 9 (DI 9, terminal X541.3) signal is interconnected to input I0 of the
"AND 0" function block of the drive.
The "energize contactor" signal of the drive is interconnected to input I1 of the "AND 0"
function block of the drive.
A "1" signal is interconnected to input I2 of the "AND 0" function block of the drive.
A "1" signal is interconnected to input I3 of the "AND 0" function block of the drive.
The output signal of the "AND 0" function block is used for the "Line contactor feedback"
signal of the drive.
