Lenze ESMD113l4TXA Frequency Inverter 11kW

ESMD113l4TXA 400V AC Drive by Lenze – 27A

Product Introduction

The ESMD113l4TXA frequency inverter combines reliable performance with practical features for motor speed control. Lenze designed this unit for 3-phase power supplies at 400 Volts AC. It handles a current rating of 27 Amperes and provides a rated output of 11 kilowatts.

Many industrial machines benefit from this inverter’s flexible operation. For example, conveyors, pumps, and fans all work well with the ESMD113l4TXA. Its output frequency ranges from 0 to 500 Hertz, so you can adjust motor speeds precisely. Additionally, the built-in PID controller helps maintain stable process variables like pressure or flow.

Technical Specifications

This inverter supports an input frequency of 50 to 60 Hertz. The control method uses a PID (Proportional–Integral–Derivative) controller, which improves accuracy in closed-loop systems.

Key electrical parameters include:

• Power supply voltage: 400 Volts AC

• Current rating: 27 Amperes

• Rated output: 11 kilowatts

• Output frequency range: 0 to 500 Hertz

• Overload capacity: 150 percent for 60 seconds

For connectivity, the ESMD113l4TXA offers:

• 1 analog input

• 4 digital inputs

• 1 digital relay output

Meanwhile, the protection class is IP20, which makes it suitable for installation inside electrical cabinets. The control method remains active across all operating conditions, ensuring consistent motor management.

Mechanical and Environmental Data

Dimensions are as follows:

• Height: 7.76 inches

• Width: 5.75 inches

• Depth: 7.17 inches

Weight: approximately 3.2 kg or 7.05 pounds.

The operating temperature range goes from 0 degrees Celsius to 55 degrees Celsius. For storage, temperatures between -20 and 70 degrees Celsius are acceptable. Therefore, you can keep spare units in most warehouses without special climate control.

Installation Guide

First, mount the ESMD113l4TXA vertically inside a clean, dry control cabinet. Ensure enough free space around the unit for airflow. Next, connect the 3-phase input power to the correct terminals. Use the specified wire gauges for 27 Amperes.

Then, wire the motor leads to the output terminals. Connect control signals to the analog and digital inputs as needed. Finally, apply power and configure parameters via the keypad or software. Remember to set the motor data correctly before running.

Frequently Asked Questions (FAQ)

1. Can the ESMD113l4TXA run on a single-phase input?

No. This inverter requires a 3-phase input at 400V AC. Single-phase input will not work correctly.

2. Does the overload capacity affect daily operation?

It only activates during temporary overcurrent situations. For example, the drive can deliver 150 percent of 27 Amperes for 60 seconds. Normal operation stays within rated limits.

3. How do I reset a fault on the ESMD113l4TXA?

You can press the stop/reset key on the keypad or cycle the control power. Check the manual for specific fault codes.

4. Is the PID controller easy to set up?

Yes. You assign the feedback source, which is the analog input, and then set the target value. After that, adjust the P, I, and D terms for stable control. Many applications work well with default values.

5. What happens if the operating temperature exceeds 55 degrees Celsius?

The drive may reduce its output current or trip on an overtemperature fault. Provide additional cooling or increase cabinet ventilation to avoid this situation.
