Schematic workflow for project planning

Necessary information regarding the machine to be driven

• Technical data and ambient conditions.
• Positioning accuracy.
• Speed setting range.
• Travel cycle calculation.

↓

Calculation of the relevant application data

• Travel diagram.
• Rotational speeds.
• Static, dynamic torques.
• Regenerative power.

↓

Gear unit selection

• Determining gear unit design, gear unit size, gear unit ratio.
• Checking the positioning accuracy.
• Checking the gear unit load.
• Checking the 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.)

↓

Axis module selection (perform procedure for every axis module)

• Determining the control mode.
• Motor/inverter assignment.
• Defining the PWM frequency
• Checking if the axis modules fulfill the duration and overload requirements.

↓

Power supply module selection

• Checking if the power supply module fulfills the duration and overload requirements.
• Checking the regenerative continuous power.
• Checking the power supply module - axis module combination.

↓

Selecting the braking resistor

• Checking if the braking resistor fulfills the duration and overload requirements.
• Checking the power supply module - braking resistor combination.

↓

Selection of other system components

• 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.
• Check if a one- or two-sided supply is necessary.

↓

Arrangement of the modules within the axis system

• I_MDA1 ≥ I_MDA2 ≥ I_MDA3 ≥ I_MDA4 ≥ ..... ≥ I_MDA15

↓

Ensure that all requirements have been met.
