Notes: 1 The solid, dotted, and dashed-dotted lines of the intermittent duty zone indicate the characteristics when a servomotor runs with the following combinations:
• The solid line: With a three-phase 200 V or a single-phase 230 V SERVOPACK
• The dotted line: With a single-phase 200 V SERVOPACK
• The dashed-dotted line: With a single-phase 100 V SERVOPACK
An SGMJV-A5A servomotor has the same characteristics in combination with three-phase 200 V and single-phase 200 V SERVOPACKs.
2 The characteristics of the intermittent duty zone differ depending on the supply voltages.
3 When the effective torque during intermittent duty is within the rated torque, the servomotor can be used within the intermittent duty zone.
4 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.

Notes: 1 The holding brake is only used to hold the load and cannot be used to stop the servomotor.
2 The holding brake open time and holding brake operation time vary depending on which discharge circuit is used. Make sure holding brake open time and holding brake
operation time are correct for your servomotor.

downloaded for free from our web site (http://www.e-mechatronics.com/).
An overvoltage alarm (A.400) is likely to occur during deceleration if the load moment of inertia exceeds the allowable load moment of
•
inertia. SERVOPACKs with a built-in regenerative resistor may generate a regenerative overload alarm (A.320). Take one of the following
steps if this occurs.
• Reduce the torque limit.
• Reduce the deceleration rate.
• Reduce the maximum speed.
• Install an external regenerative resistor if the alarm cannot be cleared using the steps above. Refer to Regenerative Resistors on
page 293.
Regenerative resistors are not built into SERVOPACKs for 400 W motors or less.
•
External regenerative resistors are required when this condition is exceeded or if the allowable loss capacity (W) of the built-in
•
regenerative resistor is exceeded due to regenerative drive conditions when a regenerative resistor is already built in.
