2.12-2.15 Motor V/F Table Values
(Fmiddle, Vmiddle, Fmin, Vmin)
In open loop mode the inverter applies output voltage vs. output frequency according to this
table.
2.16 - Thermal Mod
(Motor_Ther: %20 - %250)
Motor temperature is estimated by a heat model which is formed by the motor parameters.
Heat model determines the temperature of the motor by using the current and rpm of the motor.
Default value for this parameter is %100. Higher values allows more load up on motor while less
values increases thermal protection sensitivity.
2.17 – Motor Direction
(Not inverted / Inverted)
This parameter can be used to change the motor direction. If motor goes in the wrong
direction, the wires to the motor must be reversed. Motor’s direction can also be reversed easily
by using this parameter without making any wiring changes.
2.18 – Encoder Direction
(Not inverted / Inverted)
This parameter can be used to change the encoder direction. If driver gives wrong
direction error after the correct wiring of encoder in a closed-loop control, the connection of
encoder phases must be reversed. Encoder’s direction can also be reversed easily by using this
parameter without making any wiring changes.
