Drive factory settings
The drive comes from the factory ready for use in most applications, with the
following functions and settings:
• Nominal motor frequency: 50 Hz
• Motor voltage:
— 230 V (ATV31H•••M2 and M3X)
— 400 V (ATV31H•••N4)
— 600 V (ATV31H•••S6X)
• Linear ramp times: 3 seconds
• Low speed (LSP): 0 Hz
• High speed (HSP): 50 Hz
• Normal stop mode on deceleration ramp
• Stop mode in the event of a fault: Freewheel
• Motor thermal current = nominal drive current
• DC injection braking current = 0.7 x nominal drive current, for 0.5 seconds
• Constant torque operation with sensorless flux vector control
• Logic inputs:
— Two rotation directions (LI1, LI2), two-wire control
— Four preset speeds (LI3, LI4): LSP (low speed), 10 Hz, 15 Hz, 20 Hz
• Analog inputs:
— AI1 speed reference (0 to 10 V)
— AI2 (0 ± 10 V) summing of AI1
— AI3 (4–20 mA) not assigned
• Relay R1: fault relay
• Relay R2: not assigned
• Analog output AOC: 0–20 mA, representation of the motor frequency
• Automatic adaptation of the deceleration ramp in the event of excessive
braking
• Switching frequency 4 kHz, random frequency
Functions of the drive local keypad display
1. Four 7-segment displays showing information in the form of codes or
values
2. Up/down buttons for scrolling through the menus or modifying values
3. ENT button for entering a menu or saving the new value selected
4. ESC button for exiting the menus without saving
5. Two diagnostic LEDs for the CANopen bus
For ATV31H•••M2A, ATV31H•••M3XA and ATV31H•••N4A drives only:
6. Speed reference potentiometer
7. RUN: Local control of motor operation
8. STOP/RESET: Local control of motor stopping and fault reset
