Wiring - Encoder Power Supply Interface - ABB ACS380 Hardware Manual


Wiring – Encoder power supply interface
Connect the encoder power supply via the BTAC module. The same power supply
feeds power to the signal interface of the BTAC module. For the voltage and current
rating, refer to Encoder interface
If you use a 24 V encoder, you can use the 24 V DC power supply of the drive for the
encoder and BTAC module. Make sure that you do not exceed the load capacity.

Use the following table to determine if you can use the drive's supply. Add the missing
figures and sum all: the sum value must not exceed the total load capacity of the
drives' supply.
