Note:
In the servo control mode the following applies:
Linear interpolation is carried-out between the points 0 Hz / p1319 and p1326 / p1327.
For closed-loop vector control, the following applies:
Linear interpolation is carried-out between the points 0 Hz / p1310, p1320 / p1321 ... p1326 / p1327.
The voltage boost when accelerating (p1311) is also applied to the freely programmable V/Hz characteristic.
p1327[0...n]
V/f control programmable characteristic voltage 4 / Uf char U4
VECTOR
Can be changed: U, T
Data type: Floating Point
P-Group: V/f control
Min
0.0 [Veff]
Description:
In the servo control mode the following applies:
The linear characteristic for the V/f control is defined by 0 Hz / p1319 and p1326 / p1327.
For closed-loop vector control, the following applies:
The programmable characteristic for the V/f control is defined using 4 points and 0 Hz/p1310.
This parameter specifies the voltage of the fourth point along the characteristic.
Dependency:
In the servo control mode the following applies:
Activates the V/f control using p1317.
For closed-loop vector control, the following applies:
Selects the freely programmable characteristic using p1300 = 3.
Refer to: p1310, p1311, p1320, p1321, p1322, p1323, p1324, p1325, p1326

p1330[0...n]
CI: V/Hz control independent voltage setpoint / Uf U_set independ.
VECTOR
Can be changed: T
Data type: Unsigned32
P-Group: V/f control
Min
-
Description:
Sets the signal source for the voltage setpoint for V/f control with an independent voltage setpoint (p1300 = 19).
Dependency:
Selects the V/f control with independent voltage setpoint via p1300 = 19.
Refer to: p1300
p1335[0...n]
Slip compensation, scaling / Slip comp scal
VECTOR
Can be changed: U, T
Data type: Floating Point
P-Group: V/f control
Min
0.0 [%]
Description:
Sets the setpoint for slip compensation in [%] referred to r0330 (motor rated slip).
p1335 = 0.0 %: Slip compensation de-activated.
p1335 = 100.0 %: Slip is fully compensated.
Dependency:
Prerequisite for a precise slip compensation for p1335 = 100 % are the precise motor parameters (p0350 ... p0360).
If the parameters are not precisely known, a precise compensation can be achieved by varying p1335.
