3.6.5 Additional Terminal Module TM15 (option G63)
One TM31 and two TM15 Terminal Modules are already part of each standard variant of the
drive. The Terminal Modules are used for the following functions:
● Inclusion of warning and fault messages and control signals
● Communication with a higher-level control level.
With the optional additional Terminal Module TM15, you can also expand the number of digital
inputs and outputs. The expansion makes sense for the following applications:
● Reading in and processing external signals in addition to the existing terminal strip available
as standard.
● Controlling external components.
The Terminal Module TM15 comprises the following elements:
● 24 bidirectional digital inputs and outputs (isolation in three groups of eight channels).
● 24 green status LEDs for indicating the logical signal status of the relevant terminal
3.6.6 PADU8 diagnosis module (option G66)
The PADU8 diagnosis module can read up to eight analog and eight digital signals from the
control and monitoring module in the power unit. The PADU8 makes these signals available
for further processing for diagnostic purposes. The typical acquisition cycle of all channels in
parallel is 1 ms which allows rapid signal characteristics to be acquired and diagnosed
simultaneously. The acquired values are transferred to an evaluation system (e.g. notebook)
either via fiber-optic conductors or via an RJ11 socket. All the output data is available on both
the fiber optic cable output and the RJ11 socket simultaneously. This means that
measurements can be taken on the RJ11 socket without disrupting data transfer via the fiber
optic cable.
With this option, a PADU8 diagnosis module is integrated in each control section.
3.6.7 Pulse distributor for splitting speed encoder signal (option G70)
This pulse distributor is capable of splitting the encoder signal. This possibility is used, for
example, when speed list values from an HTL incremental encoder are required at various
points for measured-value acquisition and processing. The pulse distributor converts the HTL
incremental encoder signals to two separate RS422 signal outputs. The inputs are electrically
isolated from the outputs. The connection is made by means of 8-pin terminal blocks.
