AO1 DATA STORAGE (13.91) Default: 0.00
Range: -327.68 to +327.67
Storage parameter for controlling analog output AO1 eg. through
fieldbus.
In 13.12 AO1 source, select AO1 data storage. Then set this parameter
as the target of the incoming value data.
With the embedded fieldbus interface, simply set the target selection
parameter of that particular data (58.101 - 58.124) to AO1 data
storage.
AO2 DATA STORAGE (13.92) Default: 0.00
Range: -327.68 to +327.67
Storage parameter for controlling analog output AO2 eg. through
fieldbus.
In 13.22 AO2 source, select AO2 data storage. Then set this parameter
as the target of the incoming value data.
With the embedded fieldbus interface, simply set the target selection
parameter of that particular data (58.101 - 58.124) to AO2 data
storage.
START/STOP
MODE
Start and stop modes; emergency stop mode and signal source selection; DC magnetization settings;
autophasing mode selection.
AUTO RESTART TIME (21.18) Default: 5.0s
Range: 0.0 - 5.0s
0.0s Automatic restarting disabled
0.1 - 5.0s Maximum power failure duration
The motor can be automatically started after a short supply power failure
using the automatic restart function. See section Automatic restart.
When this parameter is set to 0.0 seconds, automatic restarting is
disabled. Otherwise, the parameter defines the maximum duration of the
power failure after which restarting is attempted. Note that this time also
includes the DC precharging delay.
WARNING! Before you activate the function, make sure that no
dangerous situations can occur. The function restarts
the drive automatically and continues operation after
a supply break.
Speed reference selection; motor potentiometer settings. See the control chain diagrams

SPEED REF UNLIMITED
(22.01)
Default: Read Only
Range: -30000.00 to +30000.00 RPM
Displays the output of the speed reference selection block.
See the control chain diagram. This parameter is read-only.
CRITICAL SPEED FUNCTION
(22.51)
Default: 00b
Range: 0000h - FFFFh
Enables/disables the critical speeds function. Also determines whether
the specified ranges are effective in both rotating directions or not.
See also section Critical speeds/frequencies.
