8.2 Torque-Motor Speed Characteristics
E-90
* A 100 VAC power supply can be used with a SERVOPACK version 03404 or firmware version 0004 or later.
When a 100 VAC power supply is used, reduced ratings are applied. For details, refer to 8.2 Torque-Motor Speed Charac-
teristics.
Use the input power supply within the specified voltage range: 200 VAC to 230 VAC or 100 VAC to
115 VAC
8.2 Torque-Motor Speed Characteristics
Note: 1. The characteristics of the intermittent duty zone differ depending on the supply voltages.
The solid and dotted lines of the intermittent duty zone indicate the characteristics when
a servomotor runs with the following combinations:
• The solid line: With a single-phase 200 V SERVOPACK
• The dotted line: With a single-phase 100 V SERVOPACK
2. When the effective torque is within the rated torque, the servomotor can be used within
the intermittent duty zone.
3. When the main circuit cable length exceeds 20 m, note that the intermittent duty zone of
the Torque-Motor Speed Characteristics will shrink as the line-to-line voltage drops.

Positioning completed output
signal ON if the current position is equal to the reference position ±10
pulses. External signal to control brakes.
Origin output signal ON if the motor is at the origin. (Width: 1/500 rev)
Note: Use the pulse edge that changes the signal
from OFF to ON.
