Product Overview

The 136N8928 (FC-051P1K5T4E20HXBXCXXXSXXX) is a compact and efficient VLT Micro Drive from the Danfoss FC 51 series. Rated for 1.5 kW (2.0 HP) applications, this drive is engineered for space-saving, high-reliability motor control in various industrial settings, including conveyor systems, pumps, and fans. Its robust design, featuring coated PCBs, ensures consistent operational performance even in challenging environments, while the integrated brake chopper provides the necessary functionality for applications requiring dynamic deceleration.

Technical Configuration

This drive is designed for three-phase operation within a 380-480 VAC supply range and is housed in a compact IP20 chassis suitable for panel mounting. The unit offers advanced control flexibility, featuring two analog inputs and one programmable analog output for seamless integration into automation loops. It supports both PNP and NPN logic configurations for digital I/O, accommodating a wide range of standard industrial control signals (0-24 V DC). To enhance durability in industrial environments, the internal printed circuit boards are fully coated to protect against moisture and corrosive particulates. Note that this specific configuration (X) is provided without a Local Control Panel (LCP) and without an integrated RFI filter.

Technical Specifications

FAQs

What is the purpose of the coated PCB?

The "C" coating provides a protective barrier against moisture, dust, and corrosive gases. This extends the service life of the electronics in environments where the air quality might otherwise lead to oxidation or component failure.

Does this drive require a dedicated RFI filter?

This model (HX) is supplied without an internal RFI filter. If your application or local regulatory standards require electromagnetic compatibility filtering to minimize noise, you must install an appropriate external filter.

Can I operate this drive without a Local Control Panel (LCP)?

Yes. This drive is designed for installations where control is handled remotely via fieldbus or hardwired analog/digital signals. If you require local parameter adjustment, an external LCP can be added to the unit.

What is the ambient temperature operating range?

The drive is rated for full-scale operation from 0 deg C to 50 deg C. It can operate at reduced performance levels down to -10 deg C. Ensure adequate ventilation within your enclosure to maintain these temperatures.

Installation and Operational Guidelines

• Thermal Management: The IP20 chassis requires adequate airflow for proper cooling. Maintain at least 100 mm of clearance above and below the drive to facilitate vertical convective heat dissipation. Ensure that the electrical cabinet in which the drive is mounted includes sufficient intake/exhaust ventilation.

• Wiring Standards: Use shielded motor cables to mitigate electromagnetic interference. The shield must be terminated at the drive's entry point using a 360-degree conductive clamp to provide a low-impedance path for high-frequency noise.

• Logic Configuration: Verify whether your controller uses PNP or NPN logic before connecting to the I/O terminals. The drive supports both, but incorrect configuration during commissioning can lead to signal errors or communication failures.
