Defining Additional Requirements For The Application - Siemens SINAMICS G120 Operating Instructions Manual

Commissioning
5.2 Preparing for commissioning
Operate the motor in the factory setting
For basic applications, you can try to operate the drive with a rated power < 18.5 kW without
any other commissioning steps. Check whether the control quality of the drive without
commissioning is adequate for the requirements of the application.
We recommend that you configure the drive with the precise motor data.
5.2.3

Defining additional requirements for the application

What speed limits should be set (minimum and maximum speed)?
● Minimum speed - factory setting 20 % of the rated speed
The minimum speed is the lowest motor speed independent of the speed setpoint.
● 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 depending on the Power Module, 10 seconds or
20 seconds
● Ramp-down time - factory setting depending on the Power Module, 10 seconds or
30 seconds
