Inverter factory setting
Motor
With its factory settings, the inverter is set up for an induction motor suitable for the power
rating of the Power Module.
Inverter interfaces
The inputs and outputs and the fieldbus interface of the inverter have specific functions when
set to the factory settings.
Switching the motor on and off
The inverter is set in the factory as follows:
● After the ON command, the motor accelerates with a ramp-up time of 10 s (referred to
1500 rpm) to its speed setpoint.
● After the OFF1 command, the motor brakes down to standstill with 10 s ramp-down time.
● The motor direction of rotation reverses with the reversing command.
Image 5-1
The ramp-up and ramp-down times define the maximum motor acceleration when the speed
setpoint changes. The ramp-up and ramp-down time is derived from the time between motor
standstill and the maximum speed, or between the maximum speed and motor standstill.
