2.1
Combinations of Servomotors and SERVOPACKs
The maximum allowed load moment of inertia depends on the Servomotor and SERVOPACK
combination.
2.1.1
Combinations of Rotary Servomotors and SERVOPACKs
The maximum load moment of inertias listed here are determined by the durability of the dynamic
brake circuit, the regenerative processing circuit, and the Servomotor. Do not exceed the allow-
able load moment of inertia values given in the table when you select an external regenerative
resistor.
