EX_FEED (Jog with External Positioning)

The EX_FEED command starts movement in the specified travel direction at the specified travel
speed. Execute the NOP command to stop the operation.
When the external positioning signal is turned ON during motion, the axis is moved by the
external positioning final travel distance from the current position. If the external positioning sig-
nal does not turn ON, jogging is continued.
Execution and Operating Procedures
1.
Make sure that all of the following conditions are met.
No.

Before you change to this command during the execution of another command, you must check whether
the command can be changed and how operation changes when the command is changed. Refer to the
following section for details on changing from another command.
4.4 Changing the Command on page 4-137
2.
Set the following setting parameters.
• OL46 (External Positioning Final Travel Distance)
• OW04, Bits 4 to 7 (External Positioning Signal Setting)
• OL10 (Speed Reference Setting)
• OW12 (Speed Limit)
• OL14 (Torque/Force Limit)
• OW03, Bits 8 to B (Filter Type Selection)
• OL36 (Linear Acceleration Rate/Acceleration Time Constant)
• OL38 (Linear Deceleration Rate/Deceleration Time Constant)
Information
3.
Set the OW08 setting parameter (Motion Commands) to 34 to execute the EX_-
FEED motion command.
4.
Turn the external positioning signal ON.
The axis will move the external positioning final travel distance from the position where the signal was
detected and then it will decelerate to a stop.
When the axis stops, bit 8 (Command Execution Completed) in the IW09 monitor parameter will
change to 1 (Normal execution completed) and external positioning will end.
5.
Set OW08 to 0 to execute the NOP motion command.
This concludes the jog with external positioning operation.
Execution Condition
There must be no alarms.
The Servomotor's power must be ON.
Motion command execution for the target axis
must be completed.*
• OL10 can be changed during motion.
• An override of between 0% and 327.67% can be set for OL10.
• If OL36 and OL38 are changed during operation, the specifications of
the SERVOPACK determine whether these changes are applied to acceleration and
deceleration.
• OL14 can be changed at any time. The intended operation may not be
achieved if the set value is too small.
