(2) Duty Ratio for High Output Setting
When high output setting is enabled, duty is restrained respective to the surrounding
temperature to control heat generation by the motor unit.
Perform an operation with the duty ratio below the allowable range shown in the graph
below.
Make sure to have 1 cycle within the time described below:
Model Name Time of one cycle (T

R
)
SA5/RA4 15min. or less
SA7/RA6 10min. or less
 
Caution: Do not attempt to perform an operation with the duty ratio above the allowable
range. An operation with the duty ratio beyond the allowable range could
shorten the life of the capacitor used in the build-in controller by the generation
of heat on the motor.
