New: Automatic test of motor brakes
The control now supports the automatic motor brake test. You can carry out
an automated functional test of the motor brake after switching on the drive,
either before traversing the reference mark or through activation by PLC
Module 9143 (See "Automatic test of the motor brake" on page 985).
Configuring the
axes and spindle
New: Support for synchronized axes (gantry axes and master-slave
torque control)
In gantry axes, two or more closed-loop axes are coupled so that they can
only move simultaneously. The main axis is referred to as the master, and
the tracking axes as the slaves.
In master-slave torque control, two or more motors (master and slave) are
mechanically coupled. Because of the coupling, only one position encoder
is required. The motor to which the position encoder is assigned is the
master.
The number of slave axes in master-slave torque control and gantry
combinations is restricted by the controller unit on which the master axis is
configured. The slave axes and the master axis must be configured on the
same drive-control motherboard (DSPs). Thus, up to five slave axes are
possible per CC 61xx.
Software option 24 is required for both coupling types for synchronized
axes. For more information, see “Gantry axes" on page 765, “Activating
gantry axes" on page 1452 and “Master-slave torque control" on page 775.
New: Additional secondary axes U and V
In addition to the W axis, the control now also supports the secondary axes
U and V. These axes can be used, for example, for the programmable
control of a traversable opposing spindle, a mechatronic tailstock or a steady
rest. As an alternative, the control can display the compensated position
value of the movements of the parallel secondary axes U, V, W, and
compensate them with the principal axis. You can use the parameter
MP_parAxComp (300205) to define the default setting for the
compensation of secondary axes. For more information about the
parameter, see “Configuring parallel axes" on page 1446.
New: Current Controller and Field Angle Adjustment special operating
mode
A new special operating mode is available for adjusting the integrated
current controller and the field angle. The MOD code number 94655 is used
to open the new special operating mode. You can find a guideline for
commissioning the current controller under “Commissioning of digital axes"
on page 1089.
New: Support of analog axes/spindle
In the HSCI system, analog nominal-value outputs are now available via the
new CMA-H 04-04-00 SPI expansion module, e.g. for controlling spindles
and auxiliary axes. See also “CMA-H SPI module for analog axes" on page
78 of this Update Information. For more information about the installation,
electrical connection and configuration of the CMA-H, please see “Analog
Nominal Value Output" on page 255.
New: Oscilloscope signals for I
2
-T monitoring
Two new signals are available in the integrated oscilloscope, see also
“Integrated Oscilloscope" on page 1145:
• I2-t (mot.): Current value of I
2
-t monitoring of the motor [%]
• I2-t (p.m.): Current value of I
2
-t monitoring of the power module [%]
