APP-27: Auto Change Time
APP-28: Auto Change Level
This function is used to protect motor from running alone
for a long time by changing operation to other motor.
Auto Change is accomplished when the following
conditions are satisfied:
1) The time set in APP-27 is over.
2) The actual value of controlling amount is less than the
value set in APP-28.
3) Only one motor is running.
When above three conditions are met, the inverter stops
the running motor, and changes motor to run by the order
set in APP-26. and then continues operation according to
new order.
If Auto Change Level (APP-28) is set to ‘0’, the function is
initiated only when the motor is in Stop or Sleep state. The
