Danfoss VLT AutomationDrive FC 360 Frequency Inverter User Guide

Danfoss VLT AutomationDrive FC 360 Frequency Inverter

Introduction

This operating guide provides necessary information for qualified personnel to install and commission the AC drive. Read and follow the instructions to use the drive safely and professionally.

Do not dispose of equipment containing electrical components together with domestic waste. Collect it separately in accordance with local and currently valid legislation.

Safety

Pay particular attention to the safety instructions and general warnings to avoid the risk of death, serious injury, and equipment or property damage.

HIGH VOLTAGE

AC drives contain high voltage when connected to AC mains input.

UNINTENDED START

The motor may start from control panel, I/O inputs, or fieldbus at any time, when the drive is connected to the AC mains.

DISCHARGE TIME

The drive contains DC-link capacitors, which can remain charged even when the drive is not powered. High voltage can be present even when the warning indicator lights are o .

• Stop the motor, and disconnect AC mains, permanent magnet type motors.
• Wait for the capacitors to discharge fully and measure it before performing any service or repair work.
• The minimum waiting time is 20 minutes.

LEAKAGE CURRENT

Leakage currents of the drive exceed 3.5 mA. Make sure that the minimum size of the ground conductor complies with the local safety regulations for high touch current equipment.

• For LCP 21: The setup number shows the active setup and the edit setup. If the same setup acts as both active and edit setup, only that setup number is shown (factory setting).
• For LCP 23, the setup number shows on the upper right corner in the status mode. For example, “1(2)” means the active setup is “1” and the editing setup is “2”.

• LCP 21 shows only parameter number.
• LCP 23 shows both parmenter number and name.

3| Parameter value.
4| Motor direction indicated by a small arrow pointing either clockwise or counterclockwise. For LCP 23, it only shows in status menu on the upper right corner of the screen.
5| The triangle indicates if the LCP is in Status, Quick Menu, or Main Menu.

signal via control input or serial communi- cation overrides the local hand on command.
15| [O /Reset]| (1) Stops the motor but does not remove power to the drive. (2) Resets the drive manually after a fault has been cleared. (3) In alarm mode, the alarm is reset when the alarm condition is removed.
16| [Auto On]| Puts the system in remote operational mode, in which the drive only respond to an external start command via control terminals or bus communication.

[2] Coast inverse is the default option for parameter 5-12 Terminal 27 Digital Input. If there is no 24 V supply to terminal 27, [Hand On] does not start the motor. Connect terminal 12 to terminal 27.

Automatic Motor Adaptation (AMA)

• Via running AMA in VVC+ mode, the drive builds a mathematical model of the motor to optimize compatibility between drive and motor, and thus enhances the motor control performance.
• Some motors may be unable to run the complete version of the test. In that case, select [2] Enable Reduced AMA in parameter 1-29 Automatic Motor Adaptation (AMA).
• For best results, run the following procedure on a cold motor.

Procedure:

1. Set motor data in parameter group 1-** Load and Motor according to the motor nameplate.
2. Connect terminal 27 to terminal 12 (24 V voltage) or choose [0] No operation in parameter 5-12 Terminal 27 Digital Input.
3. Set [1] Enable Complete AMA or [2] Enable Reduced AMA for parameter 1-29 Automatic Motor Adaptation (AMA).
4. Press the [Hand On] key, the test runs automatically and the main display indicates when it is completed.
