NOTE: Maximum payloads require decreased duty cycle for continuous
operation. Please contact Adept sales for more information.
NOTE: These values apply at 15,000 km of travel which is equivalent to 25
million 300 mm pick and place cycles. For 10,000 km of travel, multiply
all values by 1.14. For 5,000 km of travel, multiply all values by 1.44.
These values are calculated in a traditional manner and assume constant
velocity, they do not take moments caused by acceleration into account.
The motors used in Python modules are high-quality AC servo motors manufactured by
Yaskawa corporation. These motors employ serial absolute encoders. The motor model
numbers, size, maximum torque values, and encoder resolution are provided here for
reference.
