or over voltage trip.

[V1-Ext]

Inverter changes its frequency reference source from keypad to ‘V1’ (analog voltage input) when this terminal is ON.

[Up, Down]

By using the Up and Down function, the drive can accelerate to a steady speed and decelerate down to a desired speed by using only two input terminals.

[3-Wire]

This function is for 3-wire start/stop control. This function is mainly used with a momentary push button to hold the current frequency output during acceleration or deceleration.

[Ext Trip-A]

This is a normally open contact input. When a terminal set to ‘Ext Trip-A’ is ON, inverter displays the fault and cuts off its output. This can be used as an external latch trip.

[Ext Trip-B]

This is a normally closed contact input. When a terminal set to ‘Ext Trip-B’ is OFF, inverter displays the fault and cuts off its output. This can be used as an external latch trip.

[Open-Loop]

This is used to exchange the control mode of inverter from PID mode (Close Loop) to V/F mode (Open Loop).

DRV-03 [Drive Mode] and DRV-04 [Frequency Mode] are applied when the mode has been changed.

☞Note: This function can be used only when the inverter is stopped.
