8.2.2 JOG operation
This paragraph describes manual forward/backward operation.
JOG operation is available as soon as the wiring is finished. It is recommended to perform
JOG operation at first in the MANU mode to check the wiring.
Outline of operation
One forward or reverse pulse corresponding to the smallest command unit is generated when
the FWD (manual forward) or RVS (manual reverse) input signal is turned ON. If the key is held
down for longer than 0.1 s, pulses are generated continuously.
Operation methods
The following methods are available to perform manual forward/reverse operation.
• FWD/RVS signal entered from an external unit.
(The FWD/RVS input signal is entered to each of the X and Y axes in the FX
2N
-20GM.)
MANU mode :Always valid
AUTO mode :Valid during m02 (END) standby
• Commands sent from a subtask (while the subtask is in the AUTO mode). (*Valid only for
the X axis in the FX
2N
-10GM.)
Turn ON M9005 (X axis, FWD) and M9021 (Y axis, FWD) or M9006 (X axis, RVS) and
M9022 (Y axis, RVS).
MANU mode :Always valid
AUTO mode :Valid during m02 (END) standby.
• Commands sent from the programmable controller. (*Valid only for the X axis in the FX
2N
-
10GM.)
Turn ON #20 b5 (X axis, FWD) and #21 b5 (Y axis FWD) or #20 b6 (X axis, FWD) and #21
b6 (Y axis, FWD).
MANU mode :Always valid
AUTO mode :Valid during m02 (END) standby
Operation example
Both the external inputs and the commands sent from the programming tool become valid by
OR processing in the positioning unit.
• The positioning unit performs the following operations in response to the command inputs.
The RVS input also generates the RP (reverse input).
• The pulse output speed can be set by PARA 5 (jog speed).
• The generated pulses are added to or subtracted from the present value register, and saved
in D9005 and D9004 for the X axis and D9015 and D9014 for the Y axis.
• In the jog operation, the positioning completion signals (M9049: X axis, M9081: Y axis) are
not turned ON after the pulse outputs are finished. Check the READY/BUSY signal (M9048:
X axis, M9080: Y axis) to confirm completion of the operation. (When the unit is in the ready
status, M9048 and M9080 are ON.)
