Code Description
AP1-58 Auto Op Time
Indicates time to activate Auto Change. In case that other conditions
for Auto Change are not met in spite of meeting the condition of
AP1-56, the value of time in AP1-58 might be bigger than the value
set at Auto Ch Time of AP1-56 because of the failure of Auto
Change.
When AP1-
55 (Auto Ch Mode) is set to ‘ 0 (None),’ the auxiliary motors operates based on
the order (sequence) set at AP1-43 (Starting Aux). Auto Change functionality is disabled.
When AP1-55 (Aut
o Ch Mode) is set to ‘1
(Aux Exchange
)’, the auxiliary motors operate
based on the order (sequence) set at AP1-43 (Starting Aux). Auto Change is activated
when auxiliary motors are in the operating state over time of AP1-56 and then every
auxiliary motor is stopped.
NOTE
Auto change does not work while the auxiliary motors are operating. Auto change is operated
only when all the auxiliary motors are stopped and if all the conditions set for the auto change
are met. When the inverter stops, all motors stop operating, and the auxiliary motor with the
highest priority becomes the starting auxiliary motor. If the inverter power is turned off then
turned back on, the auxiliary motor set at AP1-43 (Starting Aux) becomes the starting auxiliary
motor.
Start order and stop order of the auxiliary motors are based on the order set at AP1-49
(FIFO/FILO).
The following diagrams depict the auxiliary motor start and stop sequence, based on a FIFO
configuration, when the inverter operation time exceeds the auto change interval set at AP1-58.
If all the auxiliary motors are turned off and the inverter operation frequency is below the
frequency set at AP1-58 (Auto Op Time), auto change is operated. Then, when the inverter
frequency increases due to decrease in the feedback, auxiliary motor #2 starts instead of
auxiliary motor #1 due to this auto change (auxiliary motor #1 starts last, for it has the lowest
priority).
