FAQs
When installing the ACS355 drive, ensure proper enclosure protection and adequate clearance for heat dissipation. Verify three-phase power input matches the 2 HP, 17 A rating and connect motor leads compatible with AC induction or permanent magnet motors. Use Safe Torque Off wiring as part of the safety circuit, and leverage the device's built-in sequencing to minimize external controls. Plan panel space for a compact footprint and document the motor type and speed/torque requirements to optimize performance.
Yes. The ACS355 family is designed for a broad range of applications including food and beverage equipment, where reliable speed control and safety features matter. It supports Safe Torque Off for enhanced operator safety and integrates with standard IEC safety practices. Ensure the enclosure and cooling meet the environment, and align motor selection (induction or PM motors) with your process requirements.
Safe Torque Off provides an immediate, hardware-based stop to motor torque without removing power from the drive, reducing restart time and risk. This capability supports common functional safety practices and helps meet regulatory expectations for machine safety in many industries. When paired with proper interlocks and risk assessments, it simplifies compliance documentation and reduces the need for additional safety relays.
The ACS355 drive offers speed and torque control for AC induction and permanent magnet motors, with built-in sequencing options to handle multi-step processes. Its modular design supports compact installation and reduces external control electronics. This enables precise process control in packaging, textiles, and material handling while lowering energy consumption and boosting overall line efficiency.
ROI benefits come from reduced wiring and external controllers, faster commissioning due to built-in programming, and safer operation with Safe Torque Off. The drive supports flexible motor choices, allowing retrofits to existing lines without large hardware overhauls. When combined with ABB ecosystem compatibility, maintenance becomes more predictable, improving uptime and lowering life-cycle costs.
