Parameter Unit Description / Notes
NOTES!
1. Use a digital input set to "General Enable" to stop the motor
without braking.
2. Useonedigitalinputsetto"BrakingO󰀨",forextrasafety,
for monitoring the real motor standstill and disables the
braking immediately.
3. For high inertia loads it is recommended to use a PTC
motor input.
4. It is not recommended to use Optimal Braking with two and
eight pole motors.
5. See parameters: P266, P267, P268, P500, P501, P502,
P503 and see the recommended set-up at items 3.3 and
3.3.10.
“DC-Braking”
Thisisanoldande󰀩cientmethodtostopveryhighinertialoads.
 The direct current is applied all the time until the motor stops.
 One contactor is needed to short-circuit the output lines U and V.
Themethoddi󰀨ersfromSSW-03andSSW-04.
 The necessary current to stop the motor is very high and continuously
applied.
 It is not compatible with the Soft-Starter SSW-06 inside delta motor
connection.
