**Work order: Parameterize the frequency inverter **

*auxiliary aid: Technical Data Manual*

In order to enable a smooth start and stop, the drive for the conveyor belt is controlled by a VFD. Your work order is to understand the information of the motor rating plate and to determine the correct parameters for the VFD.

**A1: **Explain the information given on the rating plate.

**A2:** How should the motor be switched on our three-phase network 400 V / 230 V if you would connect it directly (Star or Delta)? Please give a short explanation!

**A3: **Determine slip, slip speed and efficiency for nominal operation and operating frequency f = 50 Hz.

**A4: **So that the belt starts and stops smoothly, choose a frequency converter. According to the manufacturer, the following motor parameters must be entered for initial commissioning:

P0304: nominal voltage

P0305: nominal current

P0307: nominal power

P0308: nominal power factor

P0310: nominal frequency

P0311: nominal speed

Enter the specific values. Missing values you have to calculate.

**A5: **The workpiece carriers (workpiece carriers) should be conveyed at a maximum speed of 0.4 m/s. For starting the acceleration for the belt should be 0.10 m/s^{2}. When stopping, the deceleration should be 0.25 m/s^{2}. To which values do you have to set the VFD parameters P0320 (ramp-up time) and P0321 (ramp-down time)?
