Aop Setpoint - Siemens SINAMICS S150 NEMA Operating Instructions Manual

Setpoint entry in LOCAL mode is unipolar. You can change the direction of rotation by
pressing the key that allows you to switch between CW/CCW rotation.
● CW rotation and "Increase key" mean:
The displayed setpoint is positive and the output frequency is increased.
● CCW rotation and "Increase key" mean:
The displayed setpoint is negative and the output frequency is increased.

AOP setpoint

Settings: MENU – Commissioning/Service – AOP Settings – Control Settings
Save AOP setpoint (factory setting: No)
● Yes: In LOCAL mode, the last setpoint (once you have released the INCREASE or
DECREASE key or confirmed a numeric entry) is saved.
The next time you switch the system on in LOCAL mode, the saved value is selected.
This is also the case if you switched to REMOTE in the meantime or the power supply
was switched off.
When the system is switched from REMOTE to LOCAL mode while the drive is switched
on (motor is running), the actual value that was last present is set as the output value for
the motorized potentiometer setpoint and saved.
If the system is switched from REMOTE to LOCAL mode while the drive is switched off,
the motorized potentiometer setpoint that was last saved is used.
● No: On power-up in LOCAL mode, the speed is always set to the value entered under
"AOP starting setpoint". When the system is switched from REMOTE to LOCAL mode
while the drive is switched on (motor is running), the actual value that was last present is
set as the output value for the AOP setpoint.
AOP setpoint ramp-up time (factory setting: 10 s)
AOP setpoint ramp-down time (factory setting: 10 s)
● Recommendation: Set as ramp-up/ramp-down time (p1120/p1121).
Changing the ramp-up/ramp-down times does not affect the settings for parameters
p1120 and p1121 because this is an AOP-specific setting.
AOP starting setpoint (factory setting: 0.000 rpm)
The AOP starting setpoint is the speed setpoint which is active when the drive is switched on
(with AOP30 - "ON" key). This setpoint is valid on condition that the system setting "Save
setpoint" is set to "NO".
Note
Internal ramp-function generator
The internal drive ramp-function generator is always active.
