(a) When control function of magnetic controller is enabled
1) Converter unit
When the forced stop (EM1) is made valid in the converter unit, the magnetic contactor is turned off
and the main circuit power supply is shut off. The drive unit in operation stops, and Main circuit off
warning (E9) appears. When the forced stop (EM1) is deactivated in the converter unit, the magnetic
contactor is turned on, the main circuit power is supplied, and then the drive unit automatically
resumes the operation.

(b) Forced stop in the drive unit
When the forced stop (EM1) is made valid in the drive unit, the drive unit in operation stops, Main circuit
off warning (E9) appears, and then the drive unit is forcedly stopped. Configure to activate the forced
stop (EM1) of the drive unit as the forced stop (EM1) of the converter unit is activated, and to activate
the forced stop (EM1) of the converter unit as the forced stop (EM1) of the drive unit is activated. Shut
off the power supply by the external sequence as soon as the forced stop (EM1) is activated.
