9.2.1 Procedure and requirements
DANGER
Danger due to faulty connection
 Observe the pin assignment of the connecting terminals.
 Make sure that all components are grounded correctly.
Output power
supply*
48 V DC ± 10% (I
nom
= 20A)
Power supply for
logic
24 V DC (to 36 V DC) + 10% / - 4%;
residual ripple below 150 mVSS;
switching peaks below 240 mVSS
Connection value
Number of modules x rated module current x 1.2
Table 19
*e.g. with Siemens Sitop Modular (order No. at Siemens: 6EP1457-3BA00)
The wiring diagrams and the cable dimensions for the lines, tem-
perature sensor and shaft encoder must be followed (see chap-
ter 6.1, page 20).
9.2.2 Connecting the STM to the MCS12 controller
Note
It is recommended to implement the power supply for the logic via
an external power supply source. Equipotential bonding is to be
performed between the power supply sources for logic and out-
put.
1.
Connect the encoder system (incremental encoder) of the
STM to terminal strips X2 and X3 of the MCS-12 controller
(for the position of the terminal strips, see Figure 7 page 35;
for the pin assignment of the terminal strips, see Table 21,
page 39)
2. Connect the STM's motor phases to terminal strip X1 of the
MCS-12 controller (see Figure 8 page 36).
3. Connect the output power supply to the MCS-12 controller
(see Table 21, page 39).
4. Connect the logic power supply to the controller MCS-12.
(see Table 21, page 39).
5. Connect the signal cable's shielding (see Table 21 and
Table 22, page 40).
