In the HSCI system, analog nominal-value outputs are available via the CMA-H 04-04-00, e.g. for
controlling spindles and auxiliary axes.
The CMA-H 04-04-00 is an optional SPI expansion module. It adds four analog nominal-value outputs
to the CC 61xx controller unit or the UEC 1xx.
Controller unit Number of CMA-H 04-04-00
modules per unit
Max. number of nominal value
outputs
CC 61xx 2 8
UEC 11x 1 4
Note
 The analog nominal-value outputs can only be accessed via the NC, and not via the PLC.
The PL 6xxx provides PLC analog outputs.
 It is not possible to control interpolating axes; only spindles and auxiliary axes that are not
interpolated together with other digital axes can be controlled.
