Miscellaneous
Abbreviation/Definition Description
Analog inputs The analog inputs can be used for controlling various functions of the frequency converter. There are
two types of analog inputs:
Current input and voltage input
Analog outputs There are two analog current outputs
AWG Means American Wire Gauge, ie. the American measuring unit for cable cross-section
Brake resistor The brake resistor is a module capable of absorbing the brake power that is generated in regenerative
braking. This regenerative braking power increases the intermediate circuit voltage and a brake chopper
ensures that the power is transmitted to the brake resistor
ccw Counter Clockwise rotation
CL Closed Loop
Coast (motor) The motor is free running to stop
CP Constant power
CT characteristics Constant torque characteristics, used for all applications, such as conveyor belts and cranes.
cw Clockwise rotation
DC Link Intermediate circuit in the frequency converter
Digital inputs The digital inputs can be used for controlling various functions of the frequency converter
Digital outputs There are four digital outputs, two of which activate relay switches.
DSP Digital Signal Processing. The FLUX processor is defined as a DSP
