Drives Solutions
VLT 6000 Series drives are specially designed for the unique
requirements of HVAC applications. Rich in standard features,
including PID control, energy optimizing capabilities, and DC-link
reactors, the VLT 6000 Series provides low motor noise with high
effi ciency. With a broad range of pre-engineered bypass panel
confi gurations and controls available, the VLT 6000 Series is the
ideal solution for a variety of HVAC applications.
Customized SetupAll drives ship with customers application
pre-programmed. After input of motor nameplate data, drive is ready
for service.
Easy-to-Use KeypadKeypads are interchangeable, allowing
parameters from one drive to be downloaded to others. Remote keypad
mounting is also available.
User can see at a glance any four of twenty-fi ve possible
displays simultaneously, such as drive frequency, current, output
kW, and output kW-h
Display can show process variables, such as %, F, C, Pa, bar,
RPM, in. wg., gal/s, gal/min, gal/hr, ft3/sec, ft3/min, ft3/hr, or
lb/in2
Monitoring Functions Missing motor phase
Output ground fault
Loss of control signal
Loss of load or broken belt
Output short circuit
Low or missing input phase
Motor overload using internal electronic I2t overload
Line and DC bus undervoltage and overvoltage; output
overcurrent
Performance Ranges208 V: 1 to 60 HP460 V: 1 to 600 HP600 V: 1 to
400 HP
EnclosuresDrive and option enclosures available in NEMA 1, NEMA
3R and NEMA 12
Depth of Features Built-in Two Setpoint PID Controller
eliminates the need for a separate setpoint or PID
controller.
Automatic Energy Optimization (AEO) constantly adjusts the motor
voltage to optimize energy savings even under changing speed and
load conditions.
Automatic Motor Adaptation (AMA) optimizes performance and effi
ciency by measuring the motors stator resistance and reactance
without running the motor or disconnecting the load.
Automatic Switching Frequency Modulation (ASFM) provides quiet
motor operation at critical low fl ow conditions and full output
without derating at high load.
Exclusive Digital Voltage Vector Control provides nearly perfect
output current sine wave and full rated motor voltage at rated
frequency, resulting in high effi ciency for both drive and
motor.
DC-Link Reactor provides harmonics mitigation equivalent to a 5%
AC line reactor, without the voltage drop and ineffi ciencies of AC
line reactors.
Firefi ghter's Override Mode can be invoked automatically by the
buildings automation system, allowing fi re and smoke to be
controlled, contained and extracted by utilizing the HVAC
system.
VLT 6000 Series Drives for HVACCommunicationsEIA-485
InterfaceFully equipped for serial communication, up to 31 drives
can be connected to one serial bus up to 5,000 feet long.
Built-in Serial CommunicationsJohnson Controls Metasys N2,
Siemens Apogee FLN (Floor Level Network), and Modbus RTU are
standard, built-in protocols. Other serial communications
capabilities are available with the optional LonWorks communication
card and VLT BACLink portal.
PC CommunciationAvailable free of charge from the Danfoss
website, the MCT 10 set-up software provides monitoring
capabilities and control of drive parameters for multiple drives
from a Windows-based PC.
OptionsBypass, Disconnect, Fuses, and Circuit Breaker option
panels are assembled at the factory's UL panel shop. All drives and
panels are built in ISO 9001 certifi ed facilities.Real-Time Clock
allows the system to anticipate conditions or override the setpoint
for a period of time, enhancing control, comfort and
efficiency.Integrated Bypass confi guration economizes space in
crowded installations.EMI, RFI Filters, Input AC Line Reactors can
supplement the harmonic protection of built-in DC link
reactors.Cascade Controller Card allows staging of up to four
additional motors or drives.
