G02, G03, G30, G31, G32, G33, G34, or G35 is designated while the tow-along tailstock body is connected. Or with the simple tow-along tailstock specification, an axis move command or turret indexing command is designated while the tailstock body is connected.

Code
None->An illegal G code is designated while the tow-along tailstock body is connected.
2->With the simple tow-along specification, axis movement or turret indexing is attempted while the tailstock body is connected.
3->In the automatic or MDI mode of operation,an axis move command is designated while the tailstock body is connected.
4->The tow-along tailstock connection command was issued in the Y-axis control mode.
5->In tow-along tailstook concatenaion, home position translocation instruction (OGL) was performed.
6->In self-travelling type tail-stock unclamp, G02,G03,G30,G31,G32,G33,G34,G35 commnd was designated.
7->In self-travelling type tail-stock unclamp, axis-movement expect for W-axis was designated.

Probable Faulty Locations
1)The tailstock body connected state is established although it is actually not connected due to faulty EC input signals.
2)Operation error
Program Example:
:
M189
G02 X100 Z50 I1 F10
:

Measures to Take
1)Correct the program.
2)Check the EC input signals

I/O check No.27 bit6 -> tailstock connection confirmation
I/O check No.27 bit7 -> tailstock disconnection confirmation

I/O check No.27 bit7 -> tailstock disconnection confirmation (ON when disconnected, OFF when connected)

3)If the code 3 appears, use the pulse handle for axis feed while the tow-along tailstock is connected.
4)After canceling the Y-axis control mode, issue the tow-along tailstock connection command.
5)After tow-along tailstook concatenaion is separated, a home position instruction is performed.
