Limits - Siemens SINAMICS S120 Commissioning Manual

• Torque control (without encoder)
• Torque control (with encoder)
Requirements
• The motor used in the device configuration of the drive axis is completely specified and
configured.
Note
This basic parameterization cannot be performed without having completed this full
configuration.
Selecting the control mode
Select one of the control modes listed above (p1300).
The screen form is structured according to the selected control mode.
Note
If a "U/f control xxx" version is selected as the control mode, 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 commissioning
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).
Ramp-up/ramp-down time always refers to the time interval from motor standstill to the set
maximum speed (without using roundings).
The OFF3 ramp-down time is effective from the maximum speed down to the motor standstill.
