7.4.5 Homing offset position setting @10
The homing offset position setting command instructs the #29 Offset distance from the home position
parameter to auto-set so that the current motor position will become the position after homing is completed from
the next time. It functions irrespectively of the operation mode. It can only be run while in the idle status.
When the command is issued, the current command unit command value and the value of the #29 parameter at
that point are added. This value is temporality stored in the #29 parameter.
The response is issued immediately.
7.4.6 Jog move command @11: Field 0
The jog move command is for performing jog operations. This command can be executed in the idle status when
the #217 Jog move operation: RS232C selection parameter is set so that operations are performed via the
RS232C interface.
When field 0 contains “1” a move in the + direction is commanded, when it contains “-1” a move in the -
direction is commanded, and when it contains “0,” a stop command is issued.
In the idle status, a jog move is performed as commanded by this command. If a start command is issued during
a jog move, the move is immediately decelerated and stopped, after which the operation is started. If the
operation is ended after that, the motor remains stopped regardless of the jog move status before starting the
operation.
The response is issued immediately.
