↓
Calculation of the relevant application data
• Travel diagram
• Rotational speeds
• Static, dynamic torques
• Regenerative power
↓
Gear unit selection
• Define gear unit size, gear unit ratio and gear unit type
• Check positioning accuracy
• Check gear unit utilization
• Check input speed
↓
Motor selection
• Maximum torque
• With dynamic drives: effective torque at medium speed
• Maximum speed
• Observe dynamic and thermal torque curves
• Motor equipment (brake, plug connector, thermal motor protection, etc.)
↓
Selecting the frequency inverter
• Specify control mode
• Check motor/inverter assignment
• Specify PWM frequency
• Check if the frequency inverters fulfill the duration and overload requirements
↓
Selecting the braking resistor
• Check if the braking resistor fulfills the duration and overload requirements
• Observe braking resistor assignment
↓
Selection of other system components
• Option cards
• Motor and supply system cables
• Signal and encoder cables
• EMC measures
↓
24V voltage supply selection
• Determine the current demand of the 24V voltage supply
• Observe the requirements for the voltage tolerance
↓
Ensure that all requirements have been met.
