Duty Cycle
The percentage of time the electric motor is
energized vs. the time it is at rest, in reversing
duty and with the actuator running at it’s rated
load - maximum published torque.
Standard Modulating Duty Rating
• 12 motor starts (corrections) per minute.
• At the rated duty cycle for that model.
• With the speed of operation a minimum
of 15 seconds for 90° or slower.
• With positioning accuracy of (+/-) 1% of total span.
