X21 digital inputs/outputs
Table 8- 53
Max. connectable cross-section: #16 AWG (1.5 mm
DI: digital input; DO: Digital output
1)
The signals of terminal block -X21 are factory-routed to customer interface -X55 (maximum
connectable cross-section: 2.5 mm
● Jumper from -X21:2 to -X55-X132:14 (ground)
● Jumper from -X21:3 to -X55-X132:12 (DI/DO14)
● Jumper from -X21:5 to -X55-X132:1 (DI4)
● Jumper from -X21:6 to -X55-X132:9 (DI/DO12)
Note
The "DO fault output" signal can be used for evaluation in the Control Unit.
On the "+24 V" signal, 24 V DC must be provided by the customer to supply the braking
module.
Note
Signal characteristics of terminal X21.3
Applying a high signal to terminal X21.3 inhibits the Braking Module. On a falling edge,
pending error messages are acknowledged.
Note
The Braking Module requires DC-link voltage so that the "No fault" message can be issued
correctly.
