Defining Additional Requirements For The Application; Restoring The Factory Setting - Siemens SIMATIC ET 200pro Original Instructions Manual

6.2.3

Defining additional requirements for the application

What speed limits should be set (minimum and maximum speed)?
● Minimum speed - factory setting 0 [rpm]
The minimum speed is the lowest speed of the motor independent of the speed setpoint.
A minimum speed is, for example, useful for fans or pumps.
● Maximum speed - factory setting 1500 [rpm]
The inverter limits the motor speed to this value.
What motor ramp-up time and ramp-down time are needed for the application?
The ramp-up and ramp-down time define the maximum motor acceleration when the speed
setpoint changes. The ramp-up and ramp-down time is the time between motor standstill and
the maximum speed, or between the maximum speed and motor standstill.
● Ramp-up time - factory setting 10 s
● Ramp-down time - factory setting 10 s

Restoring the factory setting

There are cases where something goes wrong when commissioning a drive system e.g.:
● The line voltage was interrupted during commissioning and you were not able to complete
commissioning.
● You got confused during the commissioning and you can no longer understand the
individual settings that you made.
● You do not know whether the inverter was already operational.
In cases such as these, reset the inverter to the factory setting.
Restoring the factory settings when the safety functions are enabled
If you are using the integrated safety functions of the inverter, e.g. "Safe Torque Off", you
must reset the safety functions separately from the remaining inverter settings.
The settings of the safety functions are protected by a password.
Settings that are not changed when restoring the factory setting
The communication settings and the settings of the motor standard (IEC/NEMA) are kept
when restoring the factory setting.
