Set voltage boost
The parameterisable voltage boost makes it possible to improve the starting performance for applications requiring a high starting torque.
Details
–
In 0x2B12:001 (P316.01), a permanent voltage boost can be set. ①
–
In 0x2B12:002 (P316.02), an additional voltage boost can be set for acceleration processes ②
–
Reference for the percentage setting of the voltage boost is the base voltage 0x2B01:001 (P303.01).

0x2B12:001
(P316.01)
|
V/f voltage boost: Fixed boost
(V/f boosts: Fixed V/f boost)
0.0 ... [2.5]* ... 20.0 %
* Default setting dependent on the model.
|
Constant voltage boost for V/f characteristic control without feedback.
–
100 % = V/f base voltage 0x2B01:001 (P303.01)
–
For the purpose of optimizing the start behavior for applications requiring a high starting torque.

0x2B12:002
(P316.02)
|
V/f voltage boost: Boost at acceleration
(V/f boosts: Dynam. V/f boost)
0.0 ... [0.0] ... 20.0 %
|
Additional voltage boost for V/f characteristic control without feedback.
–
100 % = V/f base voltage 0x2B01:001 (P303.01)
–
This voltage boost is only active while the motor is accelerated. It then acts in addition to the fixed voltage boost set in 0x2B12:001 (P316.01).
