Description / Notes
If even with thesesettingsthe motordoes not decelerate
within the required time, you will have the following
alternatives
-
Use the dynamic braking (for more details, refer to the
item 8.23).
-
If inverter is being operated in V/F control, increase
P136.
-
If inverteris being operated in vector control, increase
P178.
NOTE!
When dynamic braking is used, set P151 to the
maximum value.

Parameter P156 must be set from 10 % to 20 % higher
than the rated motor current (P401).
Always P401 is changed, P156 is adjusted automatically.
