Reset Inverter

The [RS] terminal causes the inverter to execute the reset operation. If the inverter is in Trip Mode, the reset cancels the Trip state. When the signal [RS] is turned ON 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.

Notes:

ξWhile the control terminal [RS] input is ON, the keypad displays alternating segments. The SRW optional remote keypad displays “HELLO!!”. After RS turns OFF, the display recovers automatically.

ξPressing the Stop/Reset key of the digital operator can generate a reset operation only when an alarm occurs.

ξA terminal configured with the [RS] function can only be configured for normally open operation. The terminal cannot be used in the normally closed contact state.

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

ξThe Stop/Reset key on the inverter is only operational for a few seconds after inverter powerup when a hand-held remote operator is connected to the inverter.

ξIf the [RS] terminal is turned ON while the motor is running, the motor will be free running (coasting).

ξIf you are using the output terminal OFF delay feature (any of C145, C147, C149 > 0.0 sec.), the [RS] terminal affects the ON-to-OFF transition slightly. Normally (without using OFF delays), the [RS] input causes the motor output and the logic outputs to turn OFF together, immediately. However, when any output uses an OFF delay, then after the [RS] input turns ON, that output will remain ON for an additional 1 sec. period (approximate) before turning OFF.
