Factory default settings for the ATV312 inverter Altivar 31xx is installed by default for the most common operating conditions

– Display: BBT is ready (rdY) when the motor is stopped and the motor frequency when the engine is running.
– Motor frequency (bFr): 50Hz.
– The application maintains a fixed moment by controlling the magnetic flux vector, without the need for a sensor.
– Normal stop mode according to acceleration / deceleration (Stt = rMP).
– Stop mode when there is an error: free
– Acceleration / deceleration steps: linear acceleration / deceleration (ACC, dEC): 3 seconds.
– Low speed (LSP): 0Hz.
– High speed (HSP): 50Hz.
– Motor thermal current (ItH) = rated motor current (dependent on BBT capacity).
– Motor braking current (SdC) = 0.7x BBT nominal current, braking time of 0.5 seconds.
– Automatic adjustment of deceleration time in case of overvoltage during braking.
– Do not start automatically after an error.
– Inverter switching frequency: 4kHz.
– Logic inputs:

• • LI1, LI2 (2-way operation): 2-wire control according to status, LI1 = forward, LI2 = invert. For ATV31xxxxxxA, these two inputs do not have a function
  • LI3, LI4: used to select 4 preset speeds (speed 1 = reference speed or equal to 0, speed 2 = 10Hz, speed 3 = 15Hz, speed 4 = 20Hz).
  • LI5-LI6: not yet assigned a function.

– Analog inputs:
– AI1: 0-10V speed reference, not yet assigned to ATV31xxxxxxA.
– AI2: Reference total speed 0 ± 10V.
– AI3: 4-20mA without assigning a function.

• • Relay R1: open contact when faulty (or power off BBT).
  • Relay R2: No function assigned.
  • AOC analog output: 0-20mA without assigning a function.

Application

Used for asynchronous motors used in applications for industrial mechanical machines and building systems such as: Conveyors, conveyors, packaging machines, mixers, crusher of lifting systems, water pump, ventilation system, ..
