Allowable Load Moment Of Inertia Scaling Factor For Servopacks Without Built-In Regenerative Resistors - YASKAWA E Series Product Manual

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

6.2.7 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
Resistor is not 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.
