Start or Stop a run via the inverter's operating panel or by switching ON or OFF between F and
CC terminals. Check the command mode, refer to Section 3.23 (page 73). To reset the
integral value by pushing the STOP key on the inverter's operating panel or by switching OFF
between F and CC terminals.
