    SSI Servo Module 

Publication

 1756-IN595A-EN-P - March 2004

The table below provides an explanation of the DRIVE indicator.

If the DRIVE 
LED displays:

The module status is:

Take this action:

Off

One of the following:

•

The axis is not 
used.

•

The axis is a 
position- only axis 
type.

•

None, if the axis is not used or 
is a position- only type.

•

Otherwise, make sure the 
module is configured, an axis 
tag has been associated with 
the module, and the axis type is 
servo.

Flashing green 
light

The axis drive is in the 
normal disabled state.

None. The servo axis state can be 
changed by executing motion 
instructions.

Steady green 
light

The axis drive is in the 
normal enabled state.

None. The servo axis state can be 
changed by executing motion 
instructions.
