616 HEIDENHAIN Technical Manual iTNC 530 HSCI
6.1.5 Assignment for spindles
With the following machine parameters you assign the position and speed
encoder inputs, the speed command output and the machine parameter block
of the current and speed controller to the spindle/spindles:
In MP109.x, enter the number of the controller's motherboard.
The HSCI address of the respective drive-control motherboard is entered in
MP109.x. The HSCI address is obtained from the position of the drive-
control motherboard in the HSCI system. However, the HSCI address to be
entered only depends on the drive-control motherboards in the system. I/O
units (PLs) and machine operating panels (MBs) are not taken into account.
This means that for the first drive-control main board, you have to enter the
address 0 in MP109, regardless of whether I/O units or machine operating
panels are located before the CC in the HSCI chain.
MP121.x is used for further assignment of the spindles to the outputs of the
respective drive-control motherboard.
In MP111.x you enter the number of the position encoder input. An error
message appears if an invalid number is entered.
In MP113.x you enter the number of the speed encoder input.
In MP121.x you enter the number of the speed command output.
In MP131.x and MP132.x you enter index number y of machine parameter
block MP2xxx.y of the current and speed controller.
With the CC 61xx controllers, the MP121.x is used to assign the outputs to the
spindles. Entering X51 to X56, X80 to X85 in MP121.x also provides all further
connector assignments to the spindle, because the assignment between
speed encoder, PWM output (power module output on the UEC) and position
encoder is permanent.
When using a CC 61xx in conjunction with HEIDENHAIN inverters
When using a UEC:
C-axis operation or a central drive is an exception where you can configure a
second position encoder input for a drive, see page 987.
