Cause
Counter-measure
A132
OFF2 missing
- Control signal [OFF2] was deactivated while
a traversing command was being executed.
- 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.
- Check the activation of control signal [OFF2]
from the user program.
- If checkback signal [OFF2] is missing, check
the supply of control word 1 (MASTERDRIVES
function diagram, sheet 180).
Note:
To activate the "in operation" [IOP] status
again, you must deactivate [OFF1] and then
activate it again.
A133
OFF3 missing
- Control signal [OFF3] was deactivated while
a traversing command was being executed.
- Checkback signal [OFF3] was deactivated
while a traversing command was being
executed.
Effect:
The motor decelerates at the current limit.
There is a subsequent pulse disable.
- Check the activation of control signal [OFF3]
from the user program.
- If checkback signal [OFF3] is missing, check
the supply of control word 1 (MASTERDRIVES
function diagram, sheet 180).
Note:
To activate the "in operation" [IOP] status
again, you must deactivate [OFF1] and then
activate it again.
A134
Enable Controller ENC
missing
The "enable controller" [ENC] control signal
was deactivated while a traversing command
was being executed (control bit No.3 "Inverter
Enable", refer to function diagram, sheet 180)
Effect:
The pulse disable is initiated immediately. If
the motor is not braked, it coasts down.
Check the activation of the "enable controller"
[ENC] control signal from the user program.
A135
Actual position value
not o.k
Actual position value not o.k. from position
sensing (B0070 / B0071)
- Check interconnection of B0070 and B0071,
- check position encoder and evaluation board,
- check encoder cable.
A136
Machine data 1
changed - RESET
necessary
Machine data 1 (position encoder type/axis
type) was changed.
Effect:
The activation of traversing commands is
inhibited.
If machine data 1 has been changed, the
"reset technology" [RST] control signal must
be activated. Alternatively switch the
MASTERDIVES electronic power supply off
and on again
A137
Axis assignment
incorrect
The same axis assignment (machine data 2)
was entered for several axes (M7 only, not
significant for the F01 technology option).
Effect:
The activation of traversing commands is
inhibited.
A unique axis assignment must be entered for
all axes on an M7-FM. For example, it is not
allowed to define two X axes.
A138
Axis assignment of roll
feed incorrect
The NC block contains an axis number which
is defined as a roll feed axis but the axis type
is defined as an incremental or absolute
position encoder (machine data 1 = 1 or 2).
(M7 only, not significant for the F01 technology
option) .
The NC block for a roll feed axis type
(machine data 1 = 3) contains:
- No axis number (X, Y, Z...)
- An incorrect axis number
Effect:
NC program execution is inhibited or aborted.
- Axis type 1 or 2:The block is not allowed to
contain an axis number which is defined as a
roll feed (M7 only).
- Axis type 3:The axis number of the roll feed
must be specified in every NC block.
