7.3 Full voltage start
When using the full voltage start the softstarter shall
ensure that the motor accelerates up to full speed as fast
as possible. This is done by providing a full voltage start
in which the motor voltage ramps up to full voltage in ½
seconds.
INFORMATION
Current limit is ignored for full voltage start.
Full voltage start is configured with the following
parameters:
Parameter
02.01 Start mode
7.4 Direct stop
When using the Direct stop the output voltage to the
motor is 0.
7
Direct stop is configured with the following
parameters:
Parameter
02.02 Stop mode
7.5 Stand still brake
The Stand still brake breakes the output to the motor,
and can be used during pre-start to assure that the
motor is standing still before Start ramp is initiated. Stand
still brake can also be controlled from a digital I/O or a
fieldbus.
Stand still brake is configured with the following
parameters:
Parameter
02.07 Pre-start function
02.08 Pre-start time
07.01 Stand still brake strength
