Danfoss 061B110266 KPI 35 Pressostat

Product Overview

The 195N2197 (VLT2955PT4B20) is a compact and highly reliable frequency converter from the legacy Danfoss VLT 2900 series. Designed for high-performance motor control in space-constrained industrial environments, this drive delivers consistent torque and precise speed regulation for a wide variety of OEM machinery. It is particularly valued in sectors such as packaging, material handling, and small-scale process automation where downtime must be minimized. The unit integrates seamlessly into existing control architectures, providing engineers with a robust tool to enhance energy efficiency and extend the operational lifespan of electric motors.

Technical Configuration

The VLT 2955 architecture is built for demanding automation tasks that require high-speed response and stable operation. This unit supports three-phase input power, providing the necessary stability for industrial-grade motor applications. It is housed in a compact chassis designed for side-by-side mounting, which is a critical feature for dense electrical cabinet layouts. The drive utilizes advanced pulse-width modulation (PWM) to reduce acoustic motor noise and minimize electromagnetic interference (EMI) within the control panel. Communication and parameter setup are handled through an integrated interface, allowing for rapid deployment and easy monitoring of drive status during active production cycles.

Technical Specifications

FAQs

Is the 195N2197 still supported for current industrial applications?

While the VLT 2900 series is considered a legacy product, it remains widely used for drop-in replacements in existing systems. For new installations, consultation with the current VLT FC series is recommended.

What is the recommended ventilation clearance for this drive?

To maintain optimal thermal conditions, a minimum of 100 mm of clearance should be provided above and below the unit. Avoid mounting heat-generating components directly above the drive to ensure the cooling fans function within design limits.

Can this drive be interfaced with a PLC via standard protocols?

Yes, the unit supports standard I/O configurations that allow for integration with most modern PLCs for speed reference and start/stop control.

Installation and Maintenance Guidelines

• Mechanical Mounting: Ensure the drive is mounted vertically on a flat, non-flammable surface. Proper orientation is essential for the internal cooling airflow. Check that the mounting screws are torqued according to industrial standards to withstand operational vibrations.
• Cable Management: Use shielded motor cables to minimize electrical noise. The motor cable shield must be clamped 360 degrees to the drive’s chassis ground to ensure effective shielding, which is critical for meeting EMC compliance in sensitive electronic environments.
• Storage and Handling: Due to the weight of the unit and the sensitive nature of the internal capacitors, ensure the device is stored in a dry, climate-controlled environment. If the drive has been in storage for more than one year, the DC-link capacitors may require a controlled reforming procedure before applying full load.
