  • Thermistor input

7
Automatic Motor Tuning
  • Perfect match between
  • motor and VLT
  • Measures the stator
  • resistance (R1)
  • Better shaft performance
  • Measurements done
  • without applying torque
  • Checks for missing
  • motor phases

8
Cold Plate
  • Reduced heating in cabinet
  • Denser installation
  • Higher enclosure class cabinets
  • Protection against
  • - Dust
  • - Dirt
  • - Humidity
  • Heat dissipates through the back of the drive

9
Flexible Mounting
  • Horizontal mounting
  • Vertical mounting
  • True side-by-side mounting
  • - No derating
  • - Also applies to modules
  • Temperature controlled fan

10
Temperature Depending Switch Frequency
  • Lowest possible motor
  • noise
  • Few inverter trips
  • Inverter protection

11
Braking Facilities
  • DC-braking
  • - Approximately 20 braking torque
  • AC-braking - Approximately 20 braking
    torque
  • Dynamic braking- Brake chopper built-in- 160
    braking torque
  • - Optional

12
Load Sharing
  • Energy savings
  • Common DC supply
  • Access to DC link

13
Process Closed Loop Control
  • Maintain a constant process value
  • - Temperature
  • - Pressure
  • - Level
  • - Speed
  • Fewer control components
  • Flexible feedback
  • - One current analogue input
  • - One voltage analogue input
  • - One pulse input (0-65 kHz)
  • All scaleable
  • Fully programmable PID controller

14
Precise Stop
  • Interrupt controlled stop
  • Higher process repeatability
  • Well defined stopping

15
Speed Compensated Stop
  • Better process control
  • Same stopping distance independent of initial
    motor speed

16
Counter Stop
  • Accurate positioning
  • High frequency input
  • (65 kHz)
  • 24V incremental encoder input
  • AB encoder input as option

17
Compliance with EMC Standards
  • Built-in EN 55011 1A filter, 25 m screened cable
  • No EMC disturbance
  • EN 55011 1B filter
  • available as module
  • IT mains compatible version with RFI filter (up
    to 4 kW)
  • VLT 2880-2882 withRFI-switch

18
Modules for improved performance
  • 1B Module- Increased RFI Protection
  • 1B/LC Module- Reduces acoustic
    motor noise
  • Motor coil module- Long motor cables 300 m

19
Reduced Harmonics
  • Less heating in installation components-
    Transformers, cables etc.
  • No disturbance of other equipment
  • Smaller cable dimensions
  • Reduced torque ripples from harmonics on mains
  • Built-in DC link chokes- In all 400 V units- In
    200 V 3 phase only units
  • Complies with IEC 61000-3-2

20
