2-2 An Overview of the Inverter
605C Frequency Inverter
Control Features
The 605C Inverter is fully-featured when controlled using the optional Operator Station (or a
suitable PC programming tool).
The `General’ control features below are not available when the unit is controlled using the
analog and digital inputs and outputs.
General Output Frequency Selectable 0-120Hz, 240Hz or 480Hz
Switching Frequency Constant Torque: selectable 3kHz or 6kHz depending on
power rating
Quadratic Torque: 3kHz for all units
Voltage Boost 0-25% (Fixed or Auto Boost)
Flux Control 1. V/F control with linear or fan law profile
2. Sensorless vector with automatic flux control and slip
compensation
Slip Compensation Compensates for motor slip for varying loads
Skip Frequencies 4 skip frequencies with adjustable skip band width
Preset Speeds 8 presets with programmable ramp rates
Stopping Modes Ramp, ramp with hold, coast, dc injection, fast stop
Ramps Symmetric or asymmetric ramp up and down rates
Raise/Lower Programmable MOP function
Jog Programmable jog speed
Logic Functions 10 programmable 3 input logic function blocks
performing NOT, AND, NAND, OR, NOR and XOR
functions
Value Functions 10 programmable 3 input value function blocks
performing IF, ABS, SWITCH, RATIO, ADD, SUB, RATIO,
TRACK/HOLD, and BINARY DECODE functions
Diagnostics Full diagnostic and monitoring facilities
Protection Trip Conditions Output short line to line, and line to earth
