Description: BICO parameter for selecting source of voltage setpoint for independent V/f control (P1300 = 19).
p1333[0...2] Start frequency for FCC / Start freq for FCC
Access level: 3
Quick comm. NO
Can be changed: U, T
Min
0.0 [%]
Description: Defines start frequency at which FCC (flux current control) is enabled as [%] of rated motor frequency (P0310).
Notice: If this value is too low, the system may become unstable.
p1334[0...2] Slip compensation activation range / Slip c. act. range
Access level: 3
Quick comm. NO
Can be changed: U, T
Min
1.0 [%]
To set the frequency activation range for slip compensation. The percentage value of P1334 refers to the motor
Description:
rated frequency P0310.
The upper threshold will always stay 4 % above P1334.
Range of slip compensation :
P1335
Dependency: Slip compensation (P1335) active.
Note: See parameter P1335.
The starting frequency of the slip compensation is P1334 * P0310.
