ACS 6000 Commissioning Manual
This group includes several optional monitoring functions. To see which
optional protection functions are in use the actual hardware set-up must
be compared with the ACS 6000 circuit diagrams and the parameters
set accordingly.
Note! All the monitoring functions are enabled by default and thus the
default settings are fail-safe.
The parameters provide settings for the internal water cooling system of
the converter (see Signal and Parameter Table, version LXAC).
The default settings of this group do not have to be changed. The only
exception is parameter 35.9 VLU Ctrl & Supervision which needs to
disabled in case a slave control unit is present in a multi-drive
configuration.
This parameter group is only used only in case the AMC3 DDCS
channel 2 is used for load sharing function between two drives in speed
control mode (e.g. hot rolling mill top and bottom motor).
Parameter 50.1 Speed Scaling defines the scaled value which
corresponds to the actual speed in rpm.
Parameter groups above 100 provide further settings regarding speed
and position measurements. See documents:

Note: Parameter group 57 is not available in all software versions.
Speed ranges which have to be avoided during operation because of
resonances can be defined in parameter group 57.
Refer to project data if the function is required.
See also section 7.2 Communication Parameters for information on
settings for the communication module.
Parameter 75.3 Encoderless Drive activates the pulse encoder for the
motor speed measurement of an asynchronous drive. Note that the
AMC controller must be re-booted to activate after the parameter has
been set.
See the wiring diagrams for optional S800 I/O module configuration and
set the parameters accordingly.
