Factory configuration
Drive factory settings
The Altivar 12 is factory-set for the most common operating conditions (motor rating according to drive rating):
• Display: drive ready (rdY) motor stopped or motor frequency reference while running
• Automatic adaptation of the deceleration ramp in the event of overvoltage on braking.
• No automatic restarting after a detected fault is cleared
• Logic inputs:
- LI1: forward (2-wire transitional control)
- LI2, LI3, LI4: no assignment
• Logic output: LO1: no assignment
• Analog input: AI1 (0 to + 5 V) speed reference
• Relay R1: the contact opens in the event of a detected fault (or drive off)
• Analog output AO1: no assignment
If the above values are compatible with the application, the drive can be used without changing the settings.
