1
* Allowable load inertia ranges require no optional external regenerative unit. Values
are 30 times the moment of inertia for 30 W (0.04 HP) to 200 W (0.27 HP) Servomo-
tors, and 20 times for 400 W (0.53 HP) and 750 W (1.01 HP) Servomotors. If load iner-
tias exceed these ranges, restrict the operation or use a regenerative unit.
2
* Supply voltage should not exceed 230 V + 10% (253 V) or 115 V + 10% (127 V). A
step-down transformer is required if the voltage should exceed these values.
3
* Use within the ambient temperature range. When enclosed in a box, the internal tem-
peratures must not exceed the ambient temperature range.
4
* N is the number of encoder pulses.
