APP-26: Auto Change Mode Selection

Factory Default:	0			0

This function is used to change the running order of the motors to regulate their run-time when multiple motors are connected for MMC.

[0]: Not using Auto Change Function.

The inverter keeps the order Main motor ⇒RLY1 ⇒ RLY2 ⇒ RLY3 ⇒ AUX and do not change the running order of auxiliary motors.

[1]: Auto Change Function is applied only to aux. motors. The inverter changes the order of auxiliary motors except the main motor connected to the drive. Running order is Main Motor ⇒ RLY1 ⇒ RLY2 ⇒ RLY3 ⇒ AUX. And then it is changed to Main Motor ⇒ RLY2 ⇒ RLY3 ⇒ AUX ⇒ RLY1.

[2]: Auto Change Function is applied to all motors. The inverter changes the order of all motors. The inverter operates the initial motor and the others are directly powered by commercial line. It should be used with Inter- lock function after configuring external inter-lock sequence circuit as shown below.

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
