 Disconnect or remove 

AC

 power to the equipment serviced 

and allow four (

4

) minutes for the capacitors to discharge 

any residual voltage.

 Make sure that the motor shaft spins freely by hand without 
effort in both directions [

fig 2

].

note: 

Replace the motor and control unit if the shaft does not spin freely 

by hand without effort.

Final checks of the motor

•  Check the mounting and fastening of the motor and control 

unit. Make sure the motor and the control unit are securely 
attached together and mounted tightly in the system.

•  Check the control unit connectors. Inspect for shorts, de-

tached wiring, or loose connections

•  Check the motor and verify the rotation of the driven load. 

Make sure it spins freely by hand in both directions without 
effort or assisted means.

•  Check all circuit breakers.

3 glossary

The glossary contains definitions for acronyms and terms oc-
curring in the Operation, Configuration, and Troubleshooting 
Manual or in the PerfectSpeed® User Interface.

ccw

Counter-clockwise direction. Motor rotation is viewed from the 
lead end of the motor, not the shaft.

cw

Clockwise direction. Motor rotation is viewed from the lead end 
of the motor, not the shaft.

dE

Demand. The set point of the motor.

ecm

Electronically Commutated Motor.

eeprom

Electronically Erasable Programmable Read Only Memory. A 
memory chip in the control capable of retaining data when the 
power supply is removed.

Inch Pounds (lb-in)

A unit of pressure resulting from a force of one pound- force 
applied to an area.

init

Appears in the digital display on the PerfectSpeed® User Inter-
face when the motor is in the process of initializing.

Input

The controlling device, 0 to 

10

 volts (

DC

).

le

The end of the motor opposite the shaft extension from which 
the rotation of the shaft and driven load are determined.

Max Power

The horsepower rating in watts delivered by the motor.

Max Speed

Maximum functioning speed of motor in Speed Mode.

Min Speed

Minimum functioning speed of motor in Speed Mode.

Max Torque

The torque point at the highest speed just below power limiting 
of the motor.
