3.2.3
Torque-Motor Speed Characteristics
*
The characteristics are the same for three-phase 200 V, single-phase 200 V, and single-phase 100 V input.
Note: 1. These values are for operation in combination with a SERVOPACK when the temperature of the armature
winding is 20
°
C. These are typical values.
2. The characteristics in the intermittent duty zone depend on the power supply voltage.
3. If the effective torque is within the allowable range for the rated torque, the Servomotor can be used within
the intermittent duty zone.
4. If you use a Servomotor Main Circuit Cable that exceeds 20 m, the intermittent duty zone in the torque-
motor speed characteristics will become smaller because the voltage drop increases.
3.2.4
Servomotor Overload Protection Characteristics
The overload detection level is set for hot start conditions with a Servomotor surrounding air
temperature of 40
°
C.
Note: The above overload protection characteristics do not mean that you can perform continuous duty operation
with an output of 100% or higher. Use the Servomotor so that the effective torque remains within the contin-
uous duty zone given in
