Direct Drive Servomotors
SGMCV (Small Capacity, with Core, Inner Rotor)
Allowable Load Moment of Inertia Scaling Factor for SERVO-
PACKs without Built-in Regenerative Resistors
The following graphs show the allowable load moment of inertia scaling factor of the motor speed
for SERVOPACKs* without built-in regenerative resistors when an External Regenerative 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.
