SJ300 Inverter

Reset Inverter The [RS] terminal causes the inverter to execute the reset operation. If the inverter is

12 ms

in Trip Mode, the reset cancels the Trip state. When the signal [RS] is turned ON

[RS]

minimum

and OFF, the inverter executes the reset operation. The minimum pulse width for [RS] must be 12 ms or greater. The alarm output will be cleared within 30 ms after the onset of the Reset command.

WARNING: After the Reset command is given and the alarm reset occurs, the motor will restart suddenly if the Run command is already active. Be sure to set the alarm reset after verifying that the Run command is OFF to prevent injury to personnel.

•The active edge (leading or trailing) of the [RS] signal is determined by the setting of C102.

•A terminal configured with the [RS] function can only be configured as a normally open contact. The terminal cannot be used in the normally closed contact state.

•When input power is turned ON, the inverter performs the same reset operation as it does when a pulse on the [RS] terminal occurs.
