MACHINE PARAMETERS.
(REF: 1402)
General machine parameters.
AXISNAME n
Name of the axes.
Possible values: X, X1··X9, ·· , C, C1··C9.
Default value: Starting from AXISNAME1; X, Y, Z...
Associated variable: (V.)MPG.AXISNAMEn
Parameter included in the AXISNAME table.
The axis name is defined by 1 or 2 characters. The first character must be one of the letters
X - Y - Z - U - V - W - A - B - C. The second character is optional and will be a numerical
suffix between 1 and 9. This way, the name of the axes may be within the range X,
X1…X9,...C, C1…C9. For example X, X1, Y3, Z9, W, W7, C...
When defining the axes, bear in mind that the order in which they are defined determines
their logic number. The first axis of the table will be logic axis -1- and so on. As with the axis
name, the logic number permits identifying the axis in PLC variables, marks, etc.
CONFIGURATION OF A TANDEM SYSTEM.
TANDEM
Table of tandem axes or spindles.
This parameter shows the table to define the tandem pairs of the system. A tandem axis
consists of two electric motors mechanically coupled to each other forming a single
transmission system (axis or spindle).
The following aspects may be pointed out in this configuration:
• A tandem axis helps provide the necessary torque to move a servo drive system when
a single motor is not capable of supplying enough torque to do it.
• Applying a pre-load torque between the main motor and the slave motor reduces the
backlash.
Requirements of the tandem systems
Each tandem pair (master and slave) must meet the following requirements:
• Each master tandem axis (spindle) admits one single slave tandem axis (spindle).
• A preload may be applied between the two motors.
• Each motor may have a different rated torque.
• The turning direction of each motor may be different from the other's.
• The torque distribution between both motors may be different from 1:1 ratio. For example,
on motors whose rated torque is different.
• Both axes and drives must be of the same type (same AXISTYPE and DRIVETYPE
parameters for both axes).
• The channel changing permission (parameter AXISEXCH) must be the same in both
axes.
• Both axes and drives must have the same software limits (same LIMIT+ and LIMIT-
parameters for both axes).
AXISNAME n Logic order.
AXISNAME 1 Logic number ·1·.
AXISNAME 2 Logic number ·2·.
AXISNAME 3 Logic number ·3·.
Managing tandem spindles and axes requires a drive version V6.14 or newer.
