Figure5-2 Switching on and switching o the motor and reversing in the factory setting
The converter is set in the factory as follows:
• After the ON command, the motor accelerates with a ramp-up time of 10s (referred to
1500rpm) 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.
The ramp-up and ramp-down times dene 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.
