Pumping, ventilating and compressing

Additional advantages

• Centrifugal pumps
• Radial/axial fans
• Compressors

• High availability through automatic restart and flying restart after power failures
• Broken belt detection by monitoring the load torque
• Pump protection against cavitation
• Hammer start and blockage clearing modes for clogged pumps
• PID controller for process values (e.g. temperature, pressure, level, flow)
• PID auto tuning to optimize controller parameters
• Hibernation mode stops the motor when demand is low
• Motor staging extends the flow range by adding two more fixed-speed drives (cascade)
• Frost and condensation protection prevents moisture in motors under extreme environmental conditions

Moving

Additional advantages

• Belt conveyors
• Roller conveyors
• Chain conveyors
• Treadmills
• Bucket conveyors

• Soft, jerk-free acceleration reduces the stress on the gear units, bearings, drums and rollers
• Super torque start for conveyor belts with high breakaway torque
• Dynamic behavior by using braking resistor or DC braking
• Direct control of mechanical holding brake
• Broken belt detection by monitoring the load torque
• Precise stopping with Quick Stop (switch-off positioning) independently from the control cycle

Processing

Additional advantages

• Single drives in the process industry
  such as mills, mixers, kneaders, crushers, mechanical presses, agitators, centrifuges
• Single drives in commercial appliances such as kitchen ovens, mixers, washing machines
• Main drives in machines with mechanically coupled axes
  such as ring spinning machines, braiding machines for textile, ropes and wire

• Frost and condensation protection prevents moisture in motors under extreme environmental conditions
• Higher productivity with uninterrupted production due to Keep Running Mode
• Exchange of regenerative energy via the DC link
• Super torque start for machines with a high breakaway torque
