6. Control Functions and Parameter Settings6-1Chapter 6 Control Functions and Parameter Settings6-1 Monitor parameters6-1 Monitor parametersThe monitor mode sequentially displays the frequency, power supply, etc., parameters recognised by theVAT2000.The symbols used in the “Application” column are:ST : Indicates parameters used for all control modes (C30-0 = 1 to 5) including V/f control (constanttorque, variable torque), sensor-less vector control, and vector control with sensor and PM motorcontrol.V/f : Indicates parameters used for V/f control (constant torque, variable torque) (C30-0 = 1, 2).VEC : Indicates parameters used for IM sensor-less vector control and IM vector control with sensor(C30-0 = 3, 4).PM : Indicates parameters that are used for PM motor control (C30-0=5)Monitor parameters listApplicationNo. Parameter Unit RemarksST V/f VEC PMD00 – Output frequency monitor0 Output frequency in Hz Hz1 Output frequency in % %will display when the VAT2000 is in standby.displays while the DC brake is in action.is displayed during pick up (Flying Start).2 Motor speed in min–1 min–13 Motor speed in % %The forward run direction is displayed with the + polarity, andthe reverse run direction with the – polarity. (This is displayedeven when stopped.) D01 – Frequency setting monitor0 Setting frequency in Hz Hz The currently selected frequency setting value is displayed. 1 Setting frequency in % % The max. frequency is displayed as 100%. 3 Setting speed(Output Ramp)min–1 The set speed at ASR input point is displayed.The forward run direction is displayed with the + polarity, andthe reverse run direction with the – polarity. 4 Setting speed(Input Ramp)min–1 The set speed at the ramp function’s input point is displayed.The forward run direction is displayed with the + polarity, andthe reverse run direction with the – polarity. D02 – Current monitor0 Output current Amps A will display when the VAT2000 is in standby. 1 Output current in % % The motor rated current is displayed as 100%. 2 Overload (OLT) monitor % OLT functions when this value reaches 100%. 3 Heatsink temperature °C 4 Torque current detection % The torque current detection value is displayed using themotor rated current as 100%. The forward run direction torqueis displayed with the + polarity, and the reverse run directiontorque with the – polarity. 5 Excitation currentdetection% The excitation current value is displayed using the motor ratedcurrent as 100%. D03 – Voltage monitor0 DC voltage V Displays the voltage of the DC link circuit in the main circuit. 1 Output voltage(command)V Displays output voltage command. The display may differ fromthe actual output voltage. will display when the drive isin standby.2 Output power kW Displays the inverter’s output power. will display whenthe drive is in standby.3 Carrier frequency kHz The current carrier frequency is displayed. D04 – Sequence status0 ~ 2 Input 3 ~ 4 OutputThe ON/OFF state of the internal sequence data will display.The correspondence of each LED segment and signal isshown in the next page.
