(6) Operation profile
This profile is based on calculation selection. The operation cycle time supposes 0.5 s.
(7) Effective torque (T
rms
)
Time-average output torque
Because the result is smaller than rated torque (0.637 Nm)
of the GYS201D5-HB2 type, continuous operation can be
made in the designated profile.
