Figure 8-23 Interconnection for "ON command"
The drive must only be switched on when a DC link voltage is available. 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) p20141 = 0
● (Drive_1) p20138 = (Drive_1) r0863.0
● (Drive_1) p20139 = 5000.00
● (Drive_1) p0861 = 5000
● (TM31) p4031 = (Drive_1) r20140

Parameterization with DCC (Drive Control Chart)

The parameter settings described in section "Parameterization with free function blocks" can
also be achieved using DCC. For this purpose the interconnections shown must be
simulated with the corresponding DCC blocks.

The "Pulse generator 0 (MFP 0)" function block is assigned to run-time group 0.
The "Control operation" signal of the drive is interconnected to the input of the "Pulse
generator 0 (MFP 0)" function block.
The pulse duration of the "Pulse generator 0 (MFP 0)" function block is set to 5000.00
ms.
The monitoring time of the line contactor is set to 5000 ms.
The output signal of the drive's "Pulse generator 0 (MPF 0)" function block is output to
digital output 1 (DO 1) of the TM31.
