EC (ELECTRONICALLY CONTROLLED) MOTOR SPEED CONTROL
EC motors are equipped with a control module that allows for accurate manual
adjustment of motor speed. Motor speed range is from 300 to 1800 rpm or
maximum rpm for that model.
The control module features a 4 digit LED display that indicates % demand of
full speed and motor speed in rpm. The display also indicates an error code
message for minor diagnostics if required.
MESSAGE DISPLAYED…
Spd- followed by the instantaneous speed in rpm
dE- followed by S + demand in %
E1- No communications
E2- Under Voltage
Motor speed can be changed by adjusting the speed control pot located on the control module. A small screwdriver can be used to make the speed adjustment.
AC SUPPLY – 120/208-230VAC
Power is connected to the motor and control module through the junction box
and wiring harness provided.
NOTE: For 115VAC operation the blue jumper provided (taped to wire
harness) must be inserted into motor power connector. See diagram.

120 VAC System
-
208-230 VAC System
CAUTION: Operating the motor at 208-230VAC with the jumper will cause significant damage to the motor.
NOTE: EC motors have a soft start feature. When the power is turned on the control module gathers information from the motor then begins the start up process. After a few seconds the motor will start to turn and reach full set speed in 10-30 seconds.
If your unit contains the ECsmart Motor please follow these wiring diagrams:

Please contact Canam Ltd. for any, and all questions related to electrical or control connections to our EC motors.
REMOTE POTENTIOMETER CONTROL
The PerfectSpeed motors accept a 0-10v control from a remote potentiometer. The “pot” can be located up to 100 feet away from the motor. This will give the motor full variable speed based on the min and max rpm set at factory.
