Code Description
AP1-56 Auto Ch Time Sets the auto change intervals.
AP1-57 Auto Ch Level
The parameter is for Main Exchange. In case that [AP1-55 Auto Ch
Mode] is set to Main Exchange, all the conditions for Auto Change
are met under the frequency in which output frequency of Main
motors are set in AP1-57. AP1-57 is the frequency to activate Auto
Change.
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 (Auto 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.
Once the auto change is operated, the auxiliary motor that started first is given the lowest
priority and all the other auxiliary motors‘ priority level increases by 1. Then, general MMC
operation continues.
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.
