Wiring diagram for basic unit
Installation
•
MCH41A (with PROFIBUS-DP) / MCH42A (with INTERBUS-LWL): SEW-EURO-
DRIVE recommends that you always supply these units with DC 24 V at terminal
X10:24 (VI24). This external DC 24 V voltage supply must be able to provide 50 W
continuous power and 100 W peak power (1s).
•
Analog input AI21 (X10:4) can be used either as a 10 V voltage input or as a TF/TH
input. It is switched over using parameter P120.
•
You can only access DIP switches S11, S12, 1 ... 8 and S1 ... S6 when the connec-
tion unit is removed (
→
Sec. "Removing the connection unit").
•
For an explanation of the function of DIP switches 1 ... 8, see the sections "Bus ter-
mination for MCH41A" and "Setting the station address with MCH41A" onpage 285
and page 287 .
•
The function of the DIP switches S1 ... S6 is explained in the section "DIP switch
settings."
•
The TF/TH line must either be shielded or routed at a distance of at least 0.2 m from
power cables (e.g. motor or brake cables). The TF/TH line must be separately shield-
ed if hybrid cables are used for the motor and TF/TH connection.
Analog output
AO1
For MCH4_A, the binary output DOØ2 (X12:5) can also be used as 0(4)...20 mA analog
output AO1. Switch the settings with parameters P621 "Binary output DOØ2" and P642
"Operating mode AO1."
NOTE
TF can be connected to X15:6 and X15:14 or X10:1 and X10:4.
•
If TF is connected to X15, set
P530 sensor type 1
to "TF/TH."
•
If TF is connected to X10, set
P120 AI2 operating mode
to "TF/TH."
With
P835 Response TF signal
you have to set the fault response.
