Hitachi SJ700-2 instruction manual 43 2nd/3rd motor control function SET and SET3

Chapter 4 Explanation of Functions

4.2.43 2nd/3rd motor control function (SET and SET3)

This motor control function allows you to switch the inverter settings to control three different types of motors. To use this function, assign function "08" (SET) and "17" (SET3) to two of the terminal [1] to [8] functions (C001 to C008). Turn the SET and SET3 terminals on and off for switching.

Item	Function code	Data	Description
Terminal function	C001 to C008	08	SET: Set 2nd motor data
		17	SET3: 3rd motor control

You can switch the following functional settings with the SET or SET3 terminal:

F002/F202/F302: Acceleration (1) time setting, 1st/2nd/3rd motors

F003/F203/F303: Deceleration (1) time setting, 1st/2nd/3rd motors

A003/A203/A303: Base frequency setting, 1st/2nd/3rd motors

A004/A204/A304: Maximum frequency setting, 1st/2nd/3rd motors

Since the inverter indicates no distinction among the 1st, 2nd, and 3rd controls, confirm the kind of control settings with the on/off states of the SET and SET3 terminals.

If both the SET and SET3 terminals are turned on, the SET terminal has priority, and the 2nd control is selected.

While the inverter is operating the motor, switching between the 1st, 2nd, and 3rd when motor stops controls is disabled. Switching the motor control is valid onlywhen the motor is stopped,so change is reflected after the operation .

The above setting items printed in italic, bold type can be adjusted even while the inverter is operating the motor. (Whether each item can be set during operation and whether it can be changed during operation are indicated in the list of data settings in Chapter 8.)
