P290 = ?
0
Input the voltage boost at frequency = 0 in %
P290 = 1
P293 = ?
Select the flux control
0: Closed-loop, flux controller active
1: Open-loop, flux controller not active
2:
Closed-loop with soft magnetization active (only for P296=3)
P095 =
1 o. 3
Input the field weakening frequency in Hz
Pre-assigned during calculation of derived motor data (P115).
P095=
2 o. 4
P294 = ?
P296 = ?
P325 = ?
Select the current controller dynamics
0: Highest dynamics
1: Average dynamics
2: Lowest dynamics
3: Optimized operation for the "field weakening" mode of
asynchronous motors
P326.1...4 = ?
Input the frequency points for curve 1 in Hz
P327.1...4 = ?
Input the voltage points for curve 1 in V
P328.1...4 = ?
Input the frequency points for curve 2 in Hz
P329.1...4 = ?
Input the voltage points for curve 2 in V
P340 = ?
Input the sampling frequency in kHz
The length of the shortest time slot T0 is also defined with the
sampling frequency.
Select type of current control
0: vector contol, e.g. for variable-speed operation
with 1FT-, 1PH4-, 1PH7(=1PA6)- and 1PL6 motors
1: v/f open-loop control e.g. for induction machines
without encoder
P357 = ?
Input the pulse frequency ratio
0: Pulse frequency = sampling frequency
1: Pulse frequency = sampling frequency / 2
P350 = ?
Input the reference value for all current variables
(normalization variable for current limitations and current
setpoints and current actual values).
P351 = ?
Input the reference value for all voltage variables
(normalization variable for voltage limitations and voltage
setpoints and voltage actual values).
