6. Function Description
6-70
6.7 2nd Function Group (2nd_[][])
2
nd
function group is equivalent to the parameter group which includes the data related to the 2
nd
motor in case
single inverter controls 2 motors. One of the multi-function terminal input P1 ~ P7 (DIO_01 ~ DIO_07) should be set to
“2nd Func” . The setting ranges and usage of the 2
nd
motor parameter is basically the same as those of the 1
st
motor
parameters. If the multi-function terminal input enables the 1
st
motor, the 1
st
motor parameters become valid.
Similiarly, if the multi-function terminal input enables the 2
nd
motor, the 2
nd
motor parameters become valid.
6.7.1 Jump code (2nd_00)
You can move on to the code you want to check using 2nd_00.
(Example) If you want to move on to 2nd_02,
After pressing the [PROG] key, set to02 using [SHIFT/ESC] / [▲(Up)] / [▼(Down)] keys and then press the [ENT]
key. If the code to jump to is not found, the nearest code number is selected.
You can check the other code using [▲(Up)] / [▼(Down)] keys.
6.7.2 2nd motor control mode selection (2nd _01)
In the motor control mode, there are speed and torque control modes based on the vector control. The speed
sensor such as the pulse encoder is required if speed control (‘Speed’) and torque control (‘Torque’) is to be used.
