Position instruction source 0
0 Position instruction source comes from external pulse.
1
Position instruction source comes from the parameter (rela-

Position control function
• When 12-04=0, position instruction is given by the pulse of A2/B2.(For the pulse given, please refer to 09-07
Encoder input mode 2)
• When 12-04=1, 2, position instruction is given by 12-20~12-49, 1 stands for relative position, 2 stands for absolute
position. See the figure below:
• Position control diagram
• When position instruction source comes from the parameter, the position control speed limit is decided by multi-
speed instruction.
• The difference between the motor actual position and position command is smaller than the setting value of the
position attained margin12-09(P.429), which is regarded as position attained. If the function setting of multi-function
digital output terminal is 21, the multi-function digits will output signals.
