10 – 10
Cause
n
The automatic, SRG,
SBH, and SH operating
states of the MCU and
CCU are compared
cyclically. If the states
are unalike for over 200
ms, a stop 1 is output.
n
Wiring error X65, X66
(,X67).
n
Safety module
defective.
<Axis>: 1 to 9 = axes 1 to 9
S1 = spindle 1
S2 = spindle 2
Cause
n
If the motor temperature
continues to increase,
the unit will be switched
off.
• Motor overload.
• Machine parameters
incorrect.
n
If the motor current
continues to increase,
the unit will be switched
off.
• Motor or power
module overload.
• Machine parameter
MP230x.x incorrect.
n
Temperature of UM1xx
power modules' heat
sinks too high.
n
If the heat-sink
temperature continues
to increase, the unit will
be switched off.
n
Speed controller waiting
for drive-on command;
PLC is not sending a
drive-on command.
Corrective action
n
Press CE to acknowledge the
error message.
n
Switch on the machine.
n

module.
Corrective action
n
Reduce the motor load.
n
Inform your service agency.
• Reduce machine
parameters.
n
Reduce motor or power
module load.
n
Inform your service agency.
• Check machine parameter
MP230x.x.
