FAQs
ACS355-03E-17A6-2 is designed to integrate with common DIN-rail and panel-mounted controller layouts used in mid-size automation cells. It supports standard wiring schemes for three-phase low-voltage AC motors, with built-in Safe Torque Off and sequence programming reducing external safety devices. When planning installation, ensure compatible supply voltage, motor type (AC induction or permanent magnet), and correct protective enclosure for your environment to minimize commissioning time.
The 4 kW rating provides robust torque for mid-sized conveyors, lifting devices, and processing machines, with a predictable current draw of 17.6 A under nominal load. The drive’s control algorithms optimize speed and torque, delivering smooth ramping, reduced mechanical stress, and improved energy efficiency. For applications with peak loads, verify motor inrush and heat dissipation to maintain steady performance.
Yes. The ACS355-03E-17A6-2 is well-suited to material handling and lifting applications due to its precise speed/torque control and built-in safety features such as Safe Torque Off. Its compatibility with both induction and PM motors expands its use across conveyors, hoists, and sorting systems. For optimal results, pair it with a compatible motor, set appropriate ramp rates, and configure STO timing to maximize uptime.
The ACS355 series is designed to meet industry safety expectations and regulatory requirements through built-in safety functionality and standard compliance practices. While certification specifics can vary by region and configuration, you can expect CE-aligned safety features and support for safety systems involving torque-off interlocks, helping to simplify regulatory alignment in EU-based and global installations.
ROI benefits come from reduced external control hardware, simplified wiring, and faster commissioning due to Safe Torque Off and sequence programming. Ongoing maintenance is streamlined because the drive centralizes motor control, reduces PLC load, and lowers spare parts counts. Over time, this translates to less downtime, improved machine availability, and lower total cost of ownership in automated lines.
