Parameters for “Voltage limitation” operating mode
Description
The MOVIFIT
®
compact motor starter increases the motor voltage along a ramp within
the set time t
U
= 0 ‑ 2 s up to the nominal value.
The starting voltage at which the acceleration procedure begins can be set within the
limits U
S
= 40 – 80% of the motor voltage U
