7-3 Description of Functions
Position function control
The followings are functions required for position control. An optional board (SC-PG) should be configured for the
position control of pulse command. Please refer to the instructions of optional board for details.

The following is the setting sequence for point to point function.
Sequence 1: Setting of point to point control command (F8102, F8115)
Set the point to point control position command. The setting range is variable according to the combination
with F8102 (
Point to Point control effective number of digits
).
・
When F8115=0: No point to point control function
・
When F8115 setting is not 0: the range will vary according to the values of F8114 and F8102. Please refer to
the above table.
※
During the setting of control command is not 0, please set the initialization value in F8115 when inputting
the deviation counter clearing signal (CCL). When inputting the deviation counter reverse clearing signal,
please set the initialization value in F8115 with a negative. Then the deviation counter connected to the
power supply will be cleared.
※
The deviation counter is a counter to count the deviations of command pulse and PG feedback pulse. When
inputting the command pulse, an optional board (SC-PG) must be configured additionally.
