Operating Manual
6.2.3.7 Motor potentiometer
Settings: MENU – Settings – Control Settings
Save motor potentiometer 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 motor potentiometer setpoint and saved.
If the system is switched from REMOTE to LOCAL mode while the drive is
switched off, the motor potentiometer setpoint that was last saved is used.
•
No : When you switch the system on in LOCAL mode, setpoint 0 is always
selected. 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 motor potentiometer setpoint.
Motor potentiometer ramp-up time (factory setting: 20 s)
Motor potentiometer ramp-down time (factory setting: 30 s)
•
Recommendation : set as ramp-up/ramp-down time (p1120 / p1121)
6.2.3.8 Operator Input Inhibit / Parameterization Inhibit
