Interconnection for "ON command"
Figure 8-39 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):
Table 8- 54 Parameterization for the interconnection for "On command"
Parameterization
(Drive_1) p20141 = 0
(Drive_1) p20138 = (Drive_1) r0863.0
(Drive_1) p20139 = 5000.00
(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.

Description
The "Pulse generator 0 (MFP 0)" function block is assigned to run-time
group 0.
The "Control operation" signal of the drive is interconnected at 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 output signal of the "Pulse generator 0 (MPF 0)" function block of the
drive is output to digital output 1 (DO 1) of the TM31.
