Details

The ATV71 family of inverter is a Schneider series of inverter with a wide power range of 0.37 to 630KW, output frequency from 0.1 to 1000Hz with over 150 functions, designed according to IEC / EN 61800-5-1 , IEC / EN 61800-3. The altivar 71 inverter is widely used in industry to control motors, converting 1 phase to 3 phase power, saving energy …

Basic specifications of their ATV 71 inverter family

– IP20 UL Type 1 series 3 phase power supply 200 … 240V with power from 0.73 … 75KW
– IP20 UL Type 1 line supplies 3 phases 380 … 480V with power from 0.75 … 500KW
– IP20 UL Type 12 line supplies 3 phases 380 … 480V with power from 0.75 … 75KW
– There are filters of electromagnetic disturbance class A or B
– Control based on magnetic flux vector
– There is auto tuning mode
– Connect with expansion cards:

• • Card extends input / output
  • Card to receive data
  • Card interface with encoder
  • Card connection control program inside
  • Card allows connecting to control many motors

– Energy saving
– Factory default settings
– Stat / stop operating status
– Application of constant torque with method of controlling sensorless magnetic flux vector (Ctt = UUC)
– Stops according to the route characteristics (Stt = RMP)
– Stop mode when there is a free wheel error – Linear speed up / down characteristics (ACC / DEC) 3s
– Low speed (LSP): 0Hz
– High speed (HSP): 50Hz
– The braking current (SdC1) = 0.7 x the rated current of the drive for 5s
– Do not automatically restart when an error occurs
– 4KHz switching frequencies for power levels up to 18Kw, 2.5Kw for higher power levels
– Logic lanes:

• • LI1 LI2 (2-way operation): 2-wire control, LI1 = forward direction, LI2 = reverse direction
  • LI1 … LI6 does not activate

– Analog input:

• • AL1: Speed ​​reference: 0-10V
  • AL2: 4-20mA does not activate

– Relay R1: the switch is opened when an error occurs
– Relay R2: not activated
– Analog output Ao1: 0-10V does not activate

Application

Designed with wide frequency range and capacity, it should be applied very flexibly in many fields, especially heavy industry:

• • Crane: system cranes, lifting, moving, twisting, elevator with speeds up to 1.2m / s
  • Transportation: conveyor systems, mining in the mining industry
  • Machines used in the exploitation and petrochemical industry
  • Weaving machines: looms, winding and discharging machines, industrial washing machines, frame tractors
  • System of large inertia machines: centrifugal pumps, mills, grinders, process control machines …
