Product Description:

The automation drive 134L1672 with the product code FC-302P3K0T5E20H1XXXXXXS001XALBXCXXXXDX is engineered for power output of 3 kW by Danfoss. It operates within an input voltage range of 3 x 380-500 V and it offers a maximum output frequency of 1000 Hz, with unlimited switching.

The 134L1672 drive provides advanced motor control for both induction and permanent magnet units, while also supports sensor-less vector control for motor types like IPM (Interior Permanent Magnet) and SPM (Surface Permanent Magnet) motors and synchronous reluctance motors. Its input current is specified as 6.5 A and it typically ranges between 1.5 to 2.5 times the rated output current, depending on load conditions. The drive supports 7.2 A of continuous and 11.5 A of periodic current for a short burst of 60 sec at 380 – 440 V, while its respective current values are rated as 6.3 A and 11.1 A at 441 – 500 V. It features an integrated back-channel cooling system to maintain operational temperatures for reliability even under heavy loads and its protection features include 120% overload capacity for 60 seconds, along with short-circuit protection. This 134L1672 drive is housed in IP20 enclosure and it supports a variety of fieldbus communication protocols, such as PROFIBUS, Modbus, EtherCAT and Ethernet/IP that allows seamless integration into automation systems.

The 134L1672 drive possess CBM monitoring to assess motor health, which minimizes downtime and maintenance costs. Its smart-start simplifies installation by guiding users through the setup process with a user-friendly interface. The unit has integrated harmonic mitigation, with typical value below 5% and it includes real-time clock (RTC) functionality feature for precise time management and scheduling. Its STO function complies with ISO 13849-1 for performance level d (PL d) and SIL 2 according to IEC 61508 to ensure safety during operations.

Frequently Asked Questions about 134L1672:

Q: Why is integrated harmonic mitigation important in the 134L1672 drive?

A: It reduces harmonic distortion below 5%, minimizing power quality issues. This ensures compliance with grid standards and protects nearby sensitive equipment.

Q: How does CBM monitoring in 134L1672 help in predictive maintenance?

A: The condition-based monitoring tracks motor performance trends over time. This allows early detection of issues before they escalate into costly downtime.

Q: What advantage does unlimited switching frequency bring to 134L1672?

A: It allows precise torque and speed control in dynamic applications. This feature is especially valuable for processes requiring rapid acceleration and deceleration.

Q: Why is STO compliance in 134L1672 important for safety systems?

A: The Safe Torque Off (STO) function disables motor torque without cutting power. This ensures safer machine servicing and meets SIL2 and PL d standards.

Q: How does the real-time clock (RTC) function improve operations?

A: It enables precise event logging and task scheduling. This helps optimize maintenance intervals and enhances traceability of operational data.
