MP-Bus cabling
| |
Risk of injury through electric shock and damage to the device! Bring the Bus Terminals system into a safe, de-energized state before starting mounting, disassembly or wiring of the Bus Terminals! |
Maximum MP-bus length
The maximum cable length is obtained by considering the following points:
- The total of the power figures for all the connected bus devices
- Wire cross-section
- AC (from firmware version B3) or DC
Operation of MP-bus slaves (actuators) with DC power supply

Operation of MP-bus slaves (actuators) with AC power supply
(from firmware version B3)

The upper power supply unit supplies the actuators with AC voltage.
The lower power supply unit supplies the MP-bus master terminal (via the power contacts of the BK, BC, BX or CX).
MP-Bus length in relation to the effective power of all drives

Example with 4 drives
Wtotal = 1.3 W + 2.5 W + 6.0 W + 3.0 W = 12.8 W
Wire cross-section in mm² | Maximum bus length |
---|---|
0.75 | 60 m |
1.00 | 80 m |
1.5 | 115 m |
2.5 | 200 m |
