*1.
These values are for operation in combination with a SERVOPACK when the temperature of the armature wind-
ing is 100
°
C. The values for other items are at 20
°
C. These are typical values.
*2.
Do not allow the effective load ratio to exceed 80% when the servo is locked or during very small round-trip
operation.
