Torque-Motor Speed Characteristics
of the SGM7G-03 to -20
*
A single-phase power input can be used in combination with the SGD7S-120A
A008.
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.
