DMC-40x0 Command Reference  OE  • 177 
OE    
FUNCTION:  Off On Error 
DESCRIPTION: 
The OE command causes the controller to shut off the motor command if a position error TE 
exceeds the limit specified by the ER command, an abort occurs from either the abort input or 
on AB command, or a limit switch is tripped, or an amplifier error exists. 
If a position error is detected on an axis, and the motion was executing an independent move, only 
that axis will be shut off.  If the motion is a part of coordinated mode of the types VM, LM or 
CM, all participating axes will be stopped. 
ARGUMENTS: OE n,n,n,n,n,n,n,n         or    OEA=n       where 
n = 0     Disables the Off On Error function.   
n = 1     Motor shut off (MO) by position error (TE > ER) or abort input 
n = 2     Motor shut off (MO) by limit switch 
n = 3  Motor shut off (MO) either by position error (TE > ER), limit switch, or abort 
input

EXAMPLES: 
OE 1,1,1,1  Enable OE on all axes 
OE 0  Disable OE on A-axis; other axes remain unchanged 
OE ,,1,1  Enable OE on C-axis and D-axis; other axes remain unchanged 
OE 1,0,1,0  Enable OE on A and C-axis; Disable OE on B and D axis 
Hint:  The OE command is useful for preventing system damage.
