Specifications of the S-PM geared motors
 In the low-speed range (less than 300r/min), the torque output can
be increased up to 100% of the setting, but continuous operation is
not possible.
 When the input voltage is low, the torque may be reduced.
 The operatable speed range at constant torque is 300r/min to
3000r/min.
Continuous operation cannot be performed in 300r/min or less.
3000r/min
 Setting Pr. 785 PM control torque boost to 50% or less enables
continuous operation at the speed less than 300r/min. However,
keep the short-time torque to Pr. 785 setting or lower.
 80% for the FR-D720-1.5K-G or lower and the FR-D740-1.5K-G or lower
 When the input voltage is low, the torque may be reduced.
 The operatable speed range at constant torque is 300r/min to
3000r/min.
