Specifications of the S-PM geared motors
7.4.2
Motor torque characteristic
<<Initial setting (
Pr. 785
= 9999 (=100%))>>
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.
<<When
Pr. 785
= 50%>>
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.
