Q. The MX2 features a PID control. PID loops are usually associated with
water control, flow control processes, heating, or process industries in gen-
eral. How could the PID loop feature be useful in my application?
A. You will need to determine the particular main variable in your applica-
tion the motor affects. That is the process variable (PV) for the motor. Over
time, a faster motor speed will cause a faster change in the PV than a slow
motor speed will. By using the PID loop feature, the inverter commands the
motor to run at the optimal speed required to maintain the PV at the de-
sired value for current conditions. Using the PID loop feature will require an
additional sensor and other wiring, and is considered an advanced appli-
cation.
The 3G3MX2 series inverters meet the following international standards.
