Example
①
Rated operational current I
e
of the motor
• I
e
motor = 29 A
②
Maximum current limiting which can be set at this 3RW51 soft starter: I
max
= 7 x 47 A = 329 A
You will find the scale of the setting element Ie on the front of the 3RW51 soft starter under the
hinged cover and in the Technical Data (Page 161).
8.3
Soft stopping
Operating principle
A voltage ramp is used to implement a smooth ramp-down. With the "voltage ramp" stopping
function, the motor voltage is decreased along a linear, negative voltage ramp until the motor
stops.
Application
• Drives that abruptly come to a stop when switched off, thereby damaging the transported
goods.
• E.g. bottle filling plants
