Limits - Siemens SINAMICS S120 Getting Started

● U/f control for drive requiring a precise frequency and FCC
● U/f control with parabolic characteristic and ECO
● Operation with braking resistor
● I/f control with fixed current
● U/f control with independent voltage setpoint
● Speed control (without encoder)
● Speed control (with encoder)
● Torque control (without encoder)
● Torque control (with encoder)
Precondition
● You have completely specified and configured the motor used in the device configuration
of the drive axis.
Note
This basic parameterization cannot be performed without having completed this full
configuration.
Selecting the control type
1. Select one of the control types listed above (p1300).
The screen form is structured according to the selected control type.
Note
If a "U/f control xxx" version is selected as the control type, other setting screen forms in
the secondary navigation of the drive axis, such as current controller or current setpoint
filter, are automatically hidden.

Description
Determines the limit value of the motor overload current.
Sets the lowest possible speed / velocity. This value is not fallen below in operation.
Sets the highest possible speed / velocity. The value is calculated during the commission-
ing phase in accordance with the motor and drive unit and can only be equal to or less
than the value in p0322 (maximum motor speed).
