Emerson’s CT drives
Thread Content
Could some expert please introduce Emerson’s drives? I couldn’t find much information online
Product Overview: The power range of Emerson CT drives varies from 0.37kW to 1.9MW. The CT drive can be configured in 5 operating modes (open-loop, closed-loop, vector, servo, and regenerative feedback mode). Emerson’s CT drives can connect to most industrial standard networks, support 14 different position feedback protocols, and offer a variety of plug-in option modules. An onboard PLC provides additional functionality, which in this project is implemented using programmable modules.

What is the difference between a CT drive and an inverter?
Inverters are used in speed control circuits; they can enable continuous adjustment of the frequency within a set range as required, which can be considered a form of \"analog\" control； The driver controls the device to move in forward, reverse, on, or off modes based on preset or inputted position signals; its output is equivalent to a \"digital signal\", and this is the most fundamental difference between these two types of devices.
Does that mean the driver needs a feedback signal? It does not involve speed control; it simply serves to start or stop the device?
