Several UV(R)
supply modules
Use of several UV(R) power supply modules
As of software version 60642x-01, it is basically possible to supply several
CC 61xx units separately via several power supply units. The NC software
determines the number of power modules existing in the system and finds out
which power module is connected to which CC 61xx. The UV that is
connected to the first CC in the HSCI chain is referred to below as the "first"
power supply module. However, there are still the following constraints for
this function in software version 60642x-01:
Plug & play is possible for power modules only if they are connected to the
first power supply module
Plug & play is possible only for the first of the power supply modules
Error conditions of all UVs are recognized and lead to the necessary
reactions. However, if several UVs are used, the error messages still apply
globally to all of the UVs. In this software version it is therefore not possible
to identify which UV has caused the error.
MP2195 for suppressing the error messages from the UV does not yet apply
to specific power supply modules, and the settings in MP2195 are globally
effective for all UVs.
When ERR.IZ.GR is sent, the spindle power limiting defined in MP2220.x
works if the spindle is included in the increased DC-link voltage. This means
that the power of the spindle is limited only if a spindle is connected to the
UV that reports the error.
The parameters in MP108/MP109 and MP2199 cannot be defined
independently of each other. MP108/MP109 is used to assign the axes/
spindles to the drive-control motherboards. MP 2199 is used to assign the
axes/spindles to the power supply modules. All axes/spindles whose power
modules are connected to a power supply module via the DC link may be
assigned only to those drive-control motherboards that are connected to the
same power supply module via the supply bus. This assignment must be
remembered and taken into account when defining the parameters. If this
assignment is not considered, a correct reaction to individual error
messages and alarms is not possible and the power of the spindle cannot
be limited in the event of ERR.IZ.GR.
