C102/C103: Reset Mode / Restart Mode – The reset mode selection, set via parameter C102,
determines how the inverter responds to the [RS] intelligent input signal or keypad Stop/Reset
key in a trip condition. The options allow you to cancel the trip on either the OFF-to-ON or
ON-to-OFF transition of [RS], and if desired, stop the inverter if it is in Run Mode. A trip event
causes the inverter output to the motor to turn OFF immediately. If in Run Mode when the trip
occurred, the inverter and motor will enter free-run stop (coasting) operation. In some applica-
tions, the motor and load will still be coasting when the inverter returns to normal Run Mode
operation. For that situation, you can configure the inverter output (C103=00) to resume opera-
tion from 0 Hz and accelerate normally. Or, you can configure the inverter (C103=01) to
resume operation from the current speed of the motor (frequency matching)—often used in
applications such as HVAC.
