Test Routine 3 - HEIDENHAIN iTNC 530 Service Manual

16.2.3 Test routine 3

General If the iTNC is in order, an error diagnosis of the inverter module UM / drive motor for UM 12x
two-axis modules can be carried out by switching the channels.

Error in X-axis

Remove the cover of the ribbon cables for the inverter modules.
 Switch the motor power stage connections X111 and X112 at the inverter module.
 Switch the motor connections X81 and X82 at the inverter module,
in the example, the motor connections of the X and Y axis on the two-axis module UM 12x.
 Switch on main switch of machine.

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.

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.
Does error display move
In example from X to Y
Channel for axis 1 (X111 / X81)
on UM 12x is defective.
to other axis?
YES
UM 12x is in order.
Error is probably at drive motor
NO
