A129 Machine data 1 (position encoder type/axis
type) is 0 (axis does not exist).
Axis does not exist -
machine data 1 = 0 Effect:
Operation of the axis is inhibited and the
position controller is deactivated.
A130 The "in operation" [IOP] checkback signal was
missing when a traversing command was
Operating conditions initiated. The following causes inhibit the "in
do not exist operation" checkback signal (status bit No.2,
refer to function diagram sheet 200) :
-Control signals [OFF1], [OFF2], [OFF3]
and/or "enable controller" [ENC] are not
activated.
-Checkback signals [OFF2] and/or [OFF3] are
not activated.
-A fault [FAULT] is active.
Effect:
The traversing command is inhibited.
A131 Control signal [OFF1] was deactivated while a
traversing command was being executed.
OFF1 missing
Effect:
The drive is brought to a standstill via a ramp
(machine data 43: deceleration time during
faults). There is a subsequent pulse disable.
A132 -Control signal [OFF2] was deactivated while a
traversing command was being executed.
OFF2 missing
-Checkback signal [OFF2] was deactivated
while a traversing command was being
executed.
Effect:
The pulse disable is initiated immediately. If
the motor is not braked, it coasts down.

Counter-measure
You must assign a valid value to machine data
1 in order to operate the axis.
Activate control signals [OFF1], [OFF2],
[OFF3] and "enable controller" [ENC].
-If checkback signals [OFF2] and/or [OFF3]
are missing, check the supply of control word
1 (MASTERDRIVE function diagram, sheet
180).
-Analyze the queued fault number
[FAULT_NO], remedy the fault, and then
cancel the fault using the acknowledge fault
[ACK_F] control signal.
Note:
To activate the "in operation" [IOP] status
again, you must deactivate [OFF1] and then
activate it again.
Check the activation of control signal [OFF1]
from the user program.
-Check the activation of control signal [OFF2]
from the user program.
-If checkback signal [OFF2] is missing, check
the supply of control word 1 (MASTERDRIVE
function diagram, sheet 180).
Note:
To activate the "in operation" [IOP] status
again, you must deactivate [OFF1] and then
activate it again.
