Instructions Manual
(3) Motor excitation stop input(M.F)
R3
Deterioration of the holding power with
the motor may cause breakage of the machine
or injury.
Check safety before inputting.
① Operating current range : 2.6mA~19.5mA
The photo-coupler turns on with
inter-terminal voltage of 4.5V~26.4V.
(Photo-coupler diode V
F
≒ 1.1 V)
● Motor output current is shut off with the photo-coupler ON.
At this time, motor torque changes to detent torque.
● When this signal is input, motor torque may be lost, resulting in failure to
retain the load transported.
In particular, this risk is high with the vertical drive (such as the Z-axis).
