Issue Details

What is the difference between c-series motor drive modules and motor drive interface modules and when do I use each in my CompactRIO?  

Solution

Motor drive modules are used when the current or power requirement of the motor fall within the specifications of the module. The motor is connected directly to the module outputs and an external excitation voltage is supplied to the module. The motor control is carried out within the module.

Motor drive interface modules are used when the motor requires higher current or power ratings than the modules can supply. In this case the module outputs to an external motor controller which then drives the motor. The motor controller is supplied with the external excitation voltage.
