2Nd/3Rd Motor Control Function (Set And Set3) - Hitachi L700 SERIES Instruction Manual

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.

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.)
