Specifications of the dedicated PM motor [S-PM geared motor]
7.5.2 Motor torque characteristic
<<Initial setting(Pr.785 =9999(=100%))>>
The short-time torque can be up to 100% in low speed (300r/min)
operation, but continuous operation is not available.
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 = 50% or less will enable
continuous operation at 300r/min or lower. However, the keep the
short-time torque to Pr.785 setting or lower.
* For FR-E720EX-1.5K or lower, it is 80% 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.
