(5) Check connector and module locations and
insertions.
.

.
.
Check that the screws on the module clamps
are tightened on the CPUrack.
Check that the clamp claws on Honda connec-
tors are tightened and that clamp screws are
securely in place.
Check that the clamp claws on power supply
connectors are in place.
Check that the clamp claws on flat cables
are in place.
(6) Check set t ings.
Verify the control power transformer setting
in reference to the input power supply voltage
(see Par. 3.2).
(7) Check input power supPly voltage and fre-
quency,
.
.
Check that the power supply voltage and fre-
quency meet ratings,
Check that the input power supply capacity
is high enough for power consumption of the
control unit.
(8) Check that the composite power supply un
outputs are not short-circuited.
Check for
short-circuit between:
.+5VandOV: +24VandOV
.+12VandoV: –12VandOV
(9) Check the output voltages after a first
power application.
.
.
(10) Check the 1/0 signals between the control
unit and the machine tool.
Check the 1/0 signals according to the list of
1/0 signals (see 9.6 standard 1/0 Diagnostic
No.
(11) Check parameters and setting data.
Conduct checkups according to the list of para-
meters (see 9.4 Parameter).
(12) Perform a second power application.
Press the POWER-ONpushbutton again for second
power application.
Depress the POWERONpushbutton for first pow-
er application.

(13) Verify the emergency stop.
With emergency stop activated (e.g., by emer-
gency stop pushbutton, machine end LS), check
that the second power supply (servo power
supply) is turned off and that the alarm dis-
play “330: EMERGENCYSTOP” appears.
