1.2.7 Duty Ratio in Continuous Operation
[1] RCP2
Operation can be performed with the duty ratio 100%.
Duty ratio is the rate of operation expressed in % that presents the time of the actuator being operated in
1 cycle of operation.
[2] RCA
Perform an operation with the duty ratio below the allowable range.
Caution: If the overload error occurs, try either to reduce the duty by extending the stop time or to
reduce the acceleration/deceleration speed.
[How to Calculation Duty]
Figure out the load ratio and acceleration/deceleration time ratio, and read the duty ratio from the graph.
If the load ratio if less than 50%, operation with 100% of the duty ratio (continuous operation) is
available.
1) Duty ratio LF
The maximum transportable weight at the rated acceleration and the rated acceleration/deceleration
speed are described in 1.2 Specifications.
Duty ratio:LF䋽 [%]
Max. Transportable Weight at Rated Acceleration : Mr [kg]
Rated Acceleration/Deceleration Speed : Dr [G]
Transported Weight during Operation : M [kg]
Acceleration/Deceleration Speed during Operation : D [G]
