JL
: Load inertia moment converted into equivalent
value on servo motor shaft
JM
: Servo motor inertia moment
No
: Servomotor speed during fast feed
TL
: Load torque converted into equivalent
value on servo motor shaft
TB
: Brake static friction torque (Note)
Note: t
and TB are the values noted in Table 9-2 Characteristics. JL is the machine's inertia mo-
