TM41 Terminal Module
■
Overview
TM41 Terminal Module
The TM41 Terminal Module supplies TTL signals which emulate
an incremental encoder, e.g. to a higher-level control. The en-
coder interface (incremental encoder emulation) can be linked
to an encoder signal from the Control Unit, e.g. incremental
encoder sin/cos, by parameter assignment.
The TM41 Terminal Module increases the number of digital inputs/
outputs and analog inputs that are available in the drive system.
■
Design
The following are located on the TM41 Terminal Module:
•
4 bidirectional digital inputs/outputs
•
4 digital inputs (with electrical isolation)
•
1 analog input
•
1 interface for emulation of TTL incremental encoder (RS422)
•
1 LED for signaling zero mark detection for encoder interface
•
2 DRIVE-CLiQ sockets
•
1 connection for the 24 V DC supply of the digital outputs
•
1 connection for the electronics power supply via the
24 V DC supply connector
•
1 PE connection
The status of the TM41 Terminal Module is indicated via a
multi-color LED.
An LED next to the interface for TTL pulse encoder emulation is
illuminated as soon as a zero mark is detected.
The TM41 Terminal Module can be snapped onto a TH 35
standard mounting rail in accordance with EN 60715 (IEC 60715).
The signal cable shield can be connected to the TM41 Terminal
Module via a shield connection terminal, e.g. type SK8 supplied
by Phoenix Contact or type KLBÜ CO 1 supplied by Weidmüller.
The shield connection terminal must not be used as a strain relief
mechanism.
■
Integration
The TM41 Terminal Module can communicate via DRIVE-CLiQ
with the following Control Units.
•
CU310-2 Control Unit
•
CU320-2 Control Unit
•
SINUMERIK Control Unit

Selection and ordering data
1)
The specified delay times refer to the hardware. The actual reaction time
depends on the time slot in which the digital input/output is processed.
2)
If the analog input is to be operated in the signal processing sense with
continuously variable input voltage, the sampling frequency
f
a
= 1/
t
time slice
must be at least twice the value of the highest signal frequency
f
max
.
