10.4.2 Precautions on Programming
Precautions on programming
• If any value such as an inching movement, acceleration time, deceleration time or target
speed is out of the specified range, a setting value error will occur at the time of startup.
• Unit memory numbers allocated to flags and start requests vary depending on axis numbers.
• A specified slot number varies depending on the installation position of the unit.
Operation at Over limit input (Limit is valid)
When JOG
operation is started
Forward
Over limit input (+): ON Not executable, Error occurs.
Over limit input (-): ON Executable
Reverse
Over limit input (+): ON Executable
Over limit input (-): ON Not executable, Error occurs.
During JOG
operation
Forward Over limit input (+): ON Deceleration stop, Limit error occurs.
Reverse Over limit input (-): ON Deceleration stop, Limit error occurs.
Operation when an error occurs
The operation of FP7 MC Unit when an error occurs varies according to the "MC common
settings" of FP7 MC Unit and the "CPU Configuration" of the CPU unit. Note that the JOG
operation may be restarted depending on the settings and execution conditions.
Example) When the execution condition for JOG is on, the operation is restarted:
Condition Unit Setting method Parameter name
①
FP7 MC Unit CMI: MC common settings
Operation when an error
occurs
All axes stop
② ⓐ
FP7 MC Unit CMI: MC common settings Error alarm to CPU unit No
② ⓑ
FP7 MC Unit CMI: MC common settings Error alarm to CPU unit Yes
CPU unit
FPWIN GR7:
FP7 Configuration > CPU
Configuration
Operation when unit error
occurs
Operation
continues.
When the setting is like the condition (1), when an error occurs during the JOG operation,
normal axes stop once. However, when the setting is like the condition (2) (a) or (2) (b), if the
JOG operation request is on, the JOG operation will start again after the stop. If such an event
needs to be avoided, add error annunciation flags of other axes as interlock release signals.
