1. Specifications
Duty ratio
The duty ratio is the operating rate, shown in %, of the actuator operating time within one cycle.
As the reference for duty available to use may differ depending on the operation conditions
(payload, acceleration/deceleration, etc.), it is necessary to figure out the load factor LF and
acceleration/deceleration time ratio t
od
using the calculation formulae below and find it out from
the graph.
1) Figure out the load factor LF using the calculation formulae below.
Maximum payload at the acceleration 0.3 G is described in 1.2 Mechanical specifications.
2) Figure out the acceleration/deceleration time ratio t
od
using the calculation formulae
below.
