* 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
* The lowest speed of the speed control range is the speed at which the motor does not
stop under 100% load.
5
* Speed regulation is defined as follows:
No-load-speed – Full-load-speed
Speed regulation =
The motor speed may change due to voltage variations or amplifier drift and changes
in processing resistance due to temperature variation.
These ratios of the speed changes to the rated speed represent the speed regulation
due to voltage and temperature variations.
6
* N is the number of encoder pulses.
