How To Connect A Pc To The Adjustable Frequency Drive; Pc Software - Danfoss VLT AutomationDrive FC 300 Design Manual

Electrical Installation
1. Use cable clamps to connect the shield to the
conductive backplate on the adjustable frequency
drive and to the metal cabinet of the brake
resistor.
2. Size the brake cable cross-section to match the
brake torque.
No. Function
81, 82 Brake resistor terminals
Table 7.71 Brake Resistor Terminals
See the Brake Resistor Design Guide for more details.
NOTICE!
If a short circuit in the brake IGBT occurs, prevent power
dissipation in the brake resistor by using a line switch or
contactor to disconnect the line power from the
adjustable frequency drive. Only the adjustable
frequency drive should control the contactor.
CAUTION
Note that voltages up to 1099 V DC may occur on the
terminals.
F-Frame Requirements
Connect the brake resistor(s) to the brake terminals in each
inverter module.
7.6.4 How to Connect a PC to the
Adjustable Frequency Drive
To control the adjustable frequency drive from a PC, install
the MCT 10 Set-up Software. The PC is connected via a
standard (host/device) USB cable, or via the RS-485
interface as shown in the section Bus Connection in the
Programming Guide.
USB is a serial bus utilizes four shielded wires with ground
pin 4 connected to the shield in the PC USB port. All
standard PCs are manufactured without galvanic isolation
in the USB port.
Follow the ground recommendations described in the
Connection to Line Power and Grounding, VLT
AutomationDrive Instruction Manual to prevent damage to
the USB host controller through the shield of the USB
cable.

Design Guide
When connecting the PC to the adjustable frequency drive
through a USB cable, Danfoss recommends using a USB
isolator with galvanic isolation to protect the PC USB host
controller from ground potential differences. It is also
recommended not to use a PC power cable with a ground
plug when the PC is connected to the adjustable
frequency drive through a USB cable. This reduces the
ground potential difference, but does not eliminate all
potential differences due to the ground and shield
connected in the PC USB port.
