Supply the fan of the braking module with the suitable supply voltage
(110 Vrms or 220 Vrms) at X7:1 and X7:2, connector (refer to figure 8.32). The
fan requires a current of about 0.14 A. The terminals 3 and 4 of the terminal
bock X7 are the NC-contact of a thermostat that must be installed for the
thermal protection of the braking module. This protection must be installed
external to the braking module (refer to figure 8.32); in this example, the relay
is connected to DI3 (XC1:3,9 of the board CC9) and the parameter P265 is
programmed as Without External Error (P265 = 4).
Figure 8.32 - Example of thermal protection
Connect the +UD grounding of the braking module to the +UD terminal of the
inverter;
Connect the -UD grounding of the braking module to the -UD terminal of the
inverter;
The control connection between the CFW-09 and the braking module is made
through a cable (0307.7560). One end of this cable is connected to the XC3
connector that can be found at the CRG4 board (refer to figure 8.33 ) in the
braking module. The other end of this cable is connected to a DB9 connector
that is fastened to a metallic support at the side of the control board in the
CFW-09.
