Design Guide | iC2-Micro Frequency Converters
MyDrive® Select
3.6.8.2
MyDrive® Select performs frequency converter sizing based on calculated motor load currents, ambient temperature, and current
limitations. The sizing results are available in graphical and numerical format, and include calculations of efficiency, power losses, and
inverter load currents. The resulting documentation is available in .pdf or .xls format, and can be imported to MyDrive® Harmonics for
evaluation of the harmonic distortion, or validation of compliance towards most recognized harmonic norms and recommendations.
MyDrive® Select is available as a web-based tool at
app stores.
3.6.8.3
MyDrive® Harmonics
MyDrive® Harmonics estimate the benefits of adding harmonic mitigation solutions to an installation and calculates system harmonic
distortion. The evaluation can be done both for new installations and when extending an existing installation.
The free version provides a fast overview of the expected general performance of the system. The expert version of MyDrive® Harmonics
requires a subscription, which opens up more features, including the possibility to save and share harmonic projects, import projects
from MyDrive® Select, and the possibility to add Danfoss harmonic mitigation products.
MyDrive® ecoSmart™
3.6.8.4
MyDrive® ecoSmart™ determines the energy efficiency of the drive being used and the system efficiency class according to IEC 61800-9.
MyDrive® ecoSmart™ uses information about the selected motor, load points, and AC drive to calculate the efficiency class and part load
efficiency for a Danfoss AC drive, either for a free-standing drive (CDM), or a drive with a motor (PDS).
MyDrive® ecoSmart™ is available as a web-based tool at
downloaded from app stores.
3.6.8.5
MyDrive® Insight
MyDrive® Insight is a software tool for commissioning, engineering, and monitoring drives. MyDrive® Insight can be used to configure
parameters, upgrade software, and set up functional safety features and condition-based monitoring.
Making backups, restoring the system from a backup, and data logging within MyDrive® Insight support the use of a microSD card as
storage device.

Brake Functions

3.7

Mechanical Holding Brake

3.7.1
A mechanical holding brake mounted directly on the motor shaft normally performs static braking.
When the holding brake is included in a safety chain, a drive cannot provide a safe control of a mechanical brake.
Include a redundancy circuitry for the brake control in the total installation.

3.7.2

Dynamic Braking

Dynamic braking is established by:
Resistor brake: A brake IGBT keeps the overvoltage under a certain threshold by directing the brake energy from the motor to the
l
connected brake resistor (parameter P 3.2.1 Enable Brake Chopper = [1] Enable). Adjust the threshold in parameter P 3.2.2 Brake
Chopper Voltage Reduce, with 70 V range for 3x380–480 V.
AC brake: The brake energy is distributed in the motor by changing the loss conditions in the motor. The AC brake function cannot
l
be used in applications with high-cycling frequency as this overheats the motor (parameter P 3.2.1 Enable Brake Chopper = [1]
Enable).
