After powering down wait at least 5 seconds (1 minute recommended) before
powering up again. If the equipment is powered “ON” and “OFF” repeatedly
without this delay, the in-rush current circuit will stop the unit from functioning.
If this happens it may take up to five minutes before the unit will power up
again.
2.2.1 Duty Cycle Calculation
Duty Cycle is rated as a percentage of the time the motor is running to the overall cycle time of
the machine. This is an important factor in determining overload protection for servo amplifiers
and motors as it directly relates to the amount of power or heat dissipation of the motor / servo
package. The rated duty cycle for the
enFORCE system is calculated as follows:
Duty Cycle Percentage (％) =
Tool Pressing Time x 100
Total Cycle Time (Tool Pressing + Tool Waiting)
Duty cycle ratings vary between tools. As a general rule, however, it should not exceed 60%. If
duty cycles remain above 60% for extended periods, a “Servo Amplifier Error / Overload” will
result (see Abnormal Code 8-10). Protection for high duty cycle is a standard feature of the
servo amplifier to prevent servo or motor damage.
