NOTE
1 When a servo amplifier is shared by more than one Power
Mate, this alarm may occur in one of the Power Mate units
if *MCON is not generated in another Power Mate unit. Set
NOFVY (bit 2 of parameter No. 1803).
2 When a two–axis amplifier is used in a 2–path Power
Mate–D, this alarm may occur in one path of the Power
Mate–D unit if *MCON is not generated in the other path.
Set NOFVY (bit 2 of parameter No. 1803).
3 The non–generation of *MCON in another Power Mate or
another path of 2–path Power Mate may be due to an
emergency stop signal being input, follow–up after the
power is turned on, or the detach function being applied.
