Comparing the RMC150 and RMC100。
I have 4 Axis, How should I choose？from Price and performance。
Use the RMC150. It is much newer, has many more features, and has much better control algorithms, such as the Output Filter that allows the Differential Gain to be used more. The RMC150 also has much better troubleshooting and diagnostic tools.
Delta does not recommend using the RMC100 for new applications, but it can be used in applications where it is already designed in.
