Procedure for configuring controlled drives
Based on the application, the drive train components are calculated and selected in the order described here. In contrast to project planning for non-controlled drives, the motor is selected after the gear unit.
- General application-side calculations
- Travel dynamics
- Output speed and gear ratio requirement
- Forces and torques
- Mass moment of inertia
- Calculating and selecting the gear unit
- Output end torques
- Selecting the gear unit
- External forces (overhung loads and axial loads)
- Calculating and selecting the motor
- Motor torques
- Motor preselection (type, size)
- Checking the drive selection
- Calculating and selecting the brake
- Special requirement for lifting applications
- Braking work and braking torque
- Selecting the brake
- Gear unit load during emergency stop braking
- Calculating and selecting the frequency inverter
- Assigning the frequency inverter based on the rated motor power
- Calculating the maximum and effective inverter current
- Selecting the frequency inverter according to calculated motor currents
- Selecting the frequency inverter for operating modes with current-controlled control
- Derating factors
- Braking resistor (optional)
