Technical Specifications

Main Features and Advantages

The core function of the ABB 3HAC16035-1​ is safety-critical: it guarantees that a multi-ton robot arm cannot drift, sag or crash when power is removed. By latching each axis brake the moment motion stops or the safety chain opens, the board provides a deterministic, hardware-enforced park position — essential when operators must enter the cell.

Reliable and stable:

The brake outputs are relay-switched and galvanically isolated from the controller logic, which means a failed brake coil or wiring short is contained at the output stage and cannot disturb the axis computer or the safety bus. This isolation is a major reason the ABB 3HAC16035-1​ is trusted in high-uptime production environments.

Fast, deterministic response:

Brake apply and release commands are executed in milliseconds, giving the controller precise authority over when each joint is free to move. The deterministic timing prevents the jerk, rebound or coasting that would otherwise compromise positioning accuracy and cycle time.

Manual release capability:

A defining advantage of the ABB 3HAC16035-1​ is its support for a manual brake-release button interface. When the cabinet is de-energised — for example after an emergency stop, collision or power failure — a technician can connect a 24 VDC external supply and individually release selected axes to manually reposition the arm or clear a jam. This is indispensable for recovery without a full system restart.

Broad robot coverage:

One board supports the entire IRC5 axis-brake interface across small, medium and large robots, simplifying the spare-parts catalogue for plants running mixed fleets.

Diagnostics and feedback:

The board reports brake status and flags over-current or short-circuit conditions back to the controller, allowing the safety system to log faults, inhibit motion and guide maintenance rather than leaving the arm in an undefined state.
