7.6 Stand still brake
The Stand-still brake function brakes the motor. Use this
during pre-start to make sure that the motor does not run
before you start the Start ramp. You can also control the
Stand-still brake from a digital I/O or a Fieldbus.
WARNING
If the Softstarter is connected inside-delta,
use of the Stand-still brake can cause
damage to the equipment.
WARNING
Because this function makes the motor
warm, we recommend to use a PTC or
PT100 element to monitor the temperature.
In some conditions, the built-in EOL is not
accurate for this feature.
INFORMATION
Stand-still brake only works when the Softstarter
is connected in-line.
