 Operation of input control/output control signals
• When the home return request (corresponding bit allocated to UM00198 to UM0019D) turns
on by a user program, the home return will start. The home return request will be enabled at
the edge where the contact turns on.
• The BUSY flag (corresponding bit allocated to UM00090 to UM00095), which indicates that
a requested operation is being controlled, will turn on when the control starts, and it will turn
off when the operation completes.
• The home return done flag (corresponding bit allocated to UM0009C to UM000A1), which
indicates the completion of operation, will turn on when the current operation is completed,
and it will be held until the next positioning control, JOG operation, or home return starts.

KEY POINTS
•
In the case of the DOG method 1, the operation stops once after the
detection of the leading edge of a near home input (HOME) as the home
return positioning control mode (Method33/34) of Servo Amplifier A6B/A5B
is used. The home position is searched at a home return creep speed again,
and the operation stops when the leading edge of the first home position (Z
phase) is detected.
