614 HEIDENHAIN Technical Manual iTNC 530 HSCI
Encoders with
multiturn
information
MP1358 is used to activate axis-specific evaluation of the multiturn
information on the respective encoders.
The reference position of the axis can be read out as usual with PLC Module
9041. If MP1358.x = 1, the return value is the position of the encoder plus the
multiturn information (e.g. 730 degrees) plus the value in MP960.x. As this
return value of the module now also includes the multiturn information of the
encoder, this needs to be considered when defining MP960.x and MP1356.x.
MP1358.x Evaluate multiturn information
Format: %0000000000000000000000
Input: 0: Do not evaluate multiturn information
1: Evaluate multiturn information
6.1.4 Assignment for axes
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 individual logic axes:
In MP108.x, enter the number of the controller's motherboard.
The HSCI address of the respective drive-control motherboard is entered in
MP108.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 motherboard, you have to enter
the address 0 in MP108, regardless of whether I/O units or machine
operating panels are located before the CC in the HSCI chain.
MP120.x is used for further assignment of the axes to the outputs of the
respective drive-control motherboard.
In MP110.x you enter the number of the position encoder input. An error
message appears if an invalid number is entered.
In MP112.x you enter the number of the speed encoder input.
In MP120.x you enter the number of the speed command output.
In MP130.x you enter index number y of machine parameter block
MP2xxx.y of the current and speed controller. This way different machine
parameter blocks MP2xxx.y can be used for the axis and spindle in C-axis
operation.
