* Note that although this servomotor can provide a stall torque of 33.6 N·m, the largest FAGOR drive that can
govern it can only get 29.5 N·m out of it.
Note.
These servomotors with “F” winding (220 Vac) can only be controlled by ACSD-
L or MCS-
L
series drives. See the tables shown in the manual of the corresponding drive to select the
servomotor-drive combination.
