2. Corresponding input IO sensor
has bad contact or is damaged or
unable to trigger
3. Parameter or file setting error
1. Execute the delay instruction in
the graphics file
2. The delay time is too long
The file name written in the electron-
ic tag is longer than 32 bytes (32
English or 16 Chinese characters)
Presser foot not raised
Unpressed frame
1. Unpressed auxiliary pressure
frame
2. Parameter setting error
1. Unpressed frame and auxiliary
frame
2. Parameter setting error
Out of punching base material
The reset fails due to various rea-
sons, such as the origin cannot be
found during reset
1. Rotary motor alarm due to me-
chanical overload, etc.
2. The motor wire of the rotating mo-
tor is disconnected, the interface
is loose, and the connection line
