Stepper Optimizer 

Stepper Optimizer provides multiple ways for you to discover what Kollmorgen step motor works best in your application. Browse our step motor catalog and discover which motor frame size will fit your application, and then modify the available voltage and current to produce a torque/speed curve for your drive. You can also use our Application Sizing section to find the best solution that fits your application requirements. You can determine a solution by identifying your required torque and speed, or through identifying your basic motion profile. The tool takes into account not only your available voltage and current, but considers your duty cycle, on time, ideal current reduction and current reduction delay.

AKD2G Safe Dynamic Braking Calculator 

The AKD2G Safe Dynamic Braking calculator is a tool that will assist you in determining the Stopping Time for the motor when using the AKD2G’s Safe Dynamic Brake (SDB) function. In some applications, it will be very beneficial to short the motor wires via “Safe” relays rather than using an electromechanical holding brake. In addition to the Stopping Time the calculator will provide you information on the Braking Current for the purpose of determining contactor and resistor ratings in the SDB circuit.

2G Performance Cable Configurator 

Cables are an important part of the complete servo system, and usually the last item thought of when creating a parts list. Selecting the correct cable set or hybrid cable can be daunting with the numerous available combinations of motor, drive and feedback options.

The 2G Performance Cable Configurator can eliminate guesswork and provide the exact cable set or hybrid cable you need to complete your servo system. Using the Configurator is a simple process of selecting:

  • Drive
  • Voltage
  • Motor family and winding
  • Feedback
  • Connector option
  • Brake option

Your cable part number can be further refined by selecting between PVC and PUR cable casing.
