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 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 vector control, the following applies:
Selects the freely programmable characteristic using p1300 = 3.
Refer to: p1310, p1311, p1317, p1319, p1320, p1321, p1322, p1323, p1324, p1325, p1326
Note: In the servo control mode the following applies:
Linear interpolation is carried out between the points 0 Hz / p1319 and p1326 / p1327.
For 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.
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
Description: Sets the setpoint for slip compensation in [%] referred to r0330 (motor rated slip).
p1335 = 0.0 %: Slip compensation de-activated.
p1335 = 100.0 %: The slip is completely 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.
Note: The purpose of slip compensation is to maintain a constant motor speed regardless of the applied load. The fact
that the motor speed decreases with increasing load is a typical characteristic of induction motors.
For synchronous motors, this effect does not occur and the parameter has no effect in this case.
For the open-loop control modes p1300 = 5 and 6 (textile sector), the slip compensation is internally disabled in
order to be able to precisely set the output frequency.
