P5 *Power system
failure* Code 5
-1115 An inrush error was
detected by the power
sequencer. This means
the high-voltage DC bus
failed to rise at the expec-
ted rate when power
was enabled.
This can occur if AC
power is abruptly
removed during the
high-power enable
sequence. If it
occurs unex-
pectedly, contact
your local Omron
support.
P6 *Power system
failure* Code 6
-1115 The MAI-2 / sMAI / sDAI
regenerative energy cir-
cuit temperature sensor
indicates an overtemp
condition.
Contact your local
Omron support.
PR None N/A A servo task has overrun
its allotted execution win-
dow.
If the problem per-
sists, contact your
local Omron support.
RC *RSC com-
munications fail-
ure*
-651 There is a failure to com-
municate with the Robot
Signature Card.

Omron support.
S0 *Safety System
Fault* Code 0
-1109* The robot hardware did
not detect that the
front-panel high-power
button was pressed prior
to the servo system
attempting to enable
power.
Contact your local
Omron support.
S1 *Safety System
Fault* Code 1
-1109* The SmartController has
signaled a power off con-
dition to the robot via
the HIPWR_DIS line on
the XSYS interface. This
fault indication typically
accompanies other fault
conditions that cause
"fatal error" on the
Smart-Controller error
(such as a loss in IEEE-
1394 communication).
Check for other mes-
sages on the
SmartController that
may indicate a fatal
error. If the error
source can be elim-
inated, re-enable
power.
S2 *Safety System
Fault* Code 2
-1109* The safety system exper-
ienced a failure on chan-
nel 1 during the cyclic
check of dual-channel
power system. This may
indicate a welded relay
If the problem per-
sists, contact your
local Omron support.
