Test Routine 4 - HEIDENHAIN iTNC 530 Service Manual

16.2.4 Test routine 4

Machine
MP 100.x
parameters used
MP 2180.x
in example
MP 120.0
MP 120.1
MP 120.2
MP 120.3
MP 121.0
MP 121.1
Example  Switch off main switch of machine.
Error in X-axis
 Remove cover from ribbon cables.
 Exchange the motor power stage connection of the defective axis with that of a functional
axis at the CC.
In the example X51 (X-axis) with X54 (Y-axis).
 Switch on main switch of machine.
 Do not acknowledge POWER INTERRUPT message. Call machine parameter list with
code number 95148.
 Exchange the input values of MP 120.x for the defective axis with those of the other axis.
In the example MP 120.0 (X-axis) = 54, MP 120.1 (Y-axis) = 51
 Acknowledge POWER INTERRUPT with CE key and switch on control voltage.
 When the inverter system and the iTNC are ready See section "Checking the Enables on the
iTNC" on page 225.
 Start positioning of axis.
16 – 238
= - - - - -CZYX (X = 1st axis, Y = 2nd axis, Z = 3rd axis, C = 4th axis)
= 0 (PWM frequency = 5 kHz for all axes)
= 51 (X-axis at motor power stage connection X51)
= 54 (Y-axis at motor power stage connection X54)
= 52 (Z-axis at motor power stage connection X52)
= 53 (C-axis at motor power stage connection X53)
= 56 (1. spindle at motor power stage connection X56)
= 0 (2. spindle not active)
Caution
Please contact your HEIDENHAIN agency, if you want to execute this routine and different
values are entered in the parameters MP2180.x.
Only encoders within the groups X51 to X56 (main controller board) and X57 to X60
(aux. controller board) may be exchanged.
In the exam ple: from X to Y
Servo am plifier, servo drive etc. are
working properly. The defect is probably
located in the CC (PW M output).
Does the error m ove
to the other axis?
YES
The defect is probably
(sevor am plifier, m otor, etc.)
