Evolution Controls Inc. is the leader in providing control solutions for the energy-efficient

EC (Electronically Commutated) Motors Market. These motors have proven energy

savings when used in Commercial and Residential applications...


We carry an innovative line of EC Motor controls giving you access

to energy savings like never before...


Using our controls, a service technician can field adjust the EC Motor's air volume

setpoint. Our controls also interface the EC Motor to automation systems

and other types of automatic controls...

EVOLUTION CONTROLS Frequently Asked Questions...

Q.        Does Evolution Controls sell Motors?

A.        No. OEMís (Original Equipment Mfgs.) please contact Regal Beloit (see links page).

Replacement motors and/or Upgrade Energy-Saving Retrofit Kits are available through Gexpro at +1 (513) 326-2124.


Q.        Can I buy controls from Evolution Controls?

A.        Yes, if you are a bona fide equipment manufacturer.

Contractors, end users and others needing Evolution Controlsí Products should contact Gexpro at +1 (513) 326-2124.


Q.        Can I use Evolutionís EC Motor controls on any EC Motor?

A.         No, the motor has to be programmed for Vspd mode.  

Most EC Motors are custom programmed by the equipment manufacturer.   

Many, especially in residential applications are not programmed for Vspd mode. 

Please contact Evolution Controls Inc. at 858-748-7359 to find out if the motor you are interested in will work with our controls.


Q.        Can I Vspd control an RB X13 motor?

A.        Maybe.  These motors are Vspd enabled for in house testing by equipment manufacturers, 

and for a very few commercial applications.  Most X13s in production equipment will not be Vspd enabled.   

Be careful not to develop a Vspd application for an X13, just to find out you will not be allowed to use it in production!


Q.        What are the Evolution Controls standard control cable pinouts?

A.        The standard pinout is 4 pins on an Amp MTA 100 header.  

Notice the solder pad (back of PC board) for the pins have three round pads and one square pad.  The square pad is pin 1.


Go = Pin 1, Status = Pin 2, Common = Pin 3, and Vspd = Pin4.

Go = White, Status = Black, Common = Green, and Vspd = Red. 

Go is used by some motors to signal the motor to run.  

Status is an output from the motor that lights the red lamp on the EVO control and provides tachometer pulses to those EVO products 

having RPM feedback.  Make sure the status output is programmed RPM only for EVO products having RPM feedback.  

Common is the common for the other three pins.  Vspd is a PWM signal with 12.5ms duration and 22Vdc peak voltage for 

most EVO/ECM controls.  Some special variations exist.


Q.        Why does my EVO/ECM-VCU display have strange numbers where there should be an RPM reading?

A.       This problem is most often because the status output (Flag 7 for RBís ECM 2.3 motor) is not programmed to RPM only. 

However, if your VCU reads 8888, this will occur the first three times the control is powered up as a factory test for the LED's 

and will disappear after a few seconds. After the third power-up, this will not occur again.
