6-1 Monitor parameters
The monitor mode sequentially displays the frequency, power supply, etc., parameters recognised by the VAT2000.
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 (constant torque, variable torque), sensor-less vector control, and vector control with sensor and PM motor control.
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)
