ABB RTAC-01 3ABD64610805

Product Features

ABB RTAC-01 3ABD64610805 supports differential or single-ended encoder connections and is compatible with various encoder output types, including push-pull, open-collector (sinking), and open-emitter (sourcing).

ABB RTAC-01 3ABD64610805 includes three signal channels: A, B, and Z. The A and B channels are speed feedback channels (with a 90° phase difference in electrical angle), while the Z channel serves as a zero-position reference with one pulse per revolution (used exclusively for positioning applications).

ABB RTAC-01 3ABD64610805 can provide 15V or 24V DC power to the encoder, with 15V as the default (selected via a jumper on the X1 terminal; terminals 4-5 connected for 15V, and 5-6 connected for 24V).

ABB RTAC-01 3ABD64610805 has a maximum output power of 5W, exceeding this requires an external power supply (the voltage selection jumper must be removed when using an external power supply).

ABB RTAC-01 3ABD64610805 is equipped with 3 diagnostic LEDs: CHA (green, indicating A channel activity), CHB (green, indicating B channel activity), and WD/INIT (yellow, indicating module status, lights up during power-on configuration).

ABB RTAC-01 3ABD64610805 can be directly installed in Slot 1 or Slot 2 of the ACS 800 driver (signal and power connections are automatically established via a 38-pin connector) or installed on a DIN rail using the external I/O module adapter AIMA-01 (not yet available at the time of release).

ABB RTAC-01 3ABD64610805 supports node address selection (set via the S1 knob when using AIMA-01, range 16-31, default 16).

ABB RTAC-01 3ABD64610805 mounting screws also serve as grounding points, meeting EMC requirements, input channels are isolated from logic circuits, power supply, and ground (test voltage 1.5kV AC, duration 1 minute).

Product Using Principle

ABB RTAC-01 3ABD64610805 is mounted on the motor shaft and generates A and B pulse signals (with a phase difference of 90°) as the motor rotates. When the motor is running in the forward direction, the A channel signal should lead the B channel by 90° electrical angle. The module converts this signal into speed or position data and transmits it to the ACS 800 drive, which adjusts its output based on this data to achieve precise control.

It is inserted into the drive's SLOT 1/2 and secured with screws (ensuring grounding and EMC compliance). The encoder power supply is connected via the X1 terminal (select 15V/24V based on encoder requirements), and the encoder signals are connected via the X2 terminal (refer to the wiring diagrams for output types, such as differential/ single-ended push-pull, open-collector, etc.), and if using the AIMA-01 adapter, set the node address (S1 knob).

During forward operation, ensure that the A-channel signal leads the B-channel (verify using an oscilloscope or encoder manual); otherwise, adjust the wiring (e.g., swap A and B channels).
