4.2.7 Allowable Load Moment of Inertia Scaling Factor for SERVOPACKs without Built-in Regenerative Resistors

4.2.7 Allowable Load Moment of Inertia Scaling Factor for
SERVOPACKs without Built-in Regenerative Resistors
The following graphs show the allowable load moment of inertia scaling factor of the motor speed for
SERVOPACKs
connected.
If the Servomotor exceeds the allowable load moment of inertia, an overvoltage alarm may occur in the
SERVOPACK.
These graphs provide reference data for deceleration at the rated torque or higher.
