7 Drive Machine Data (SIMODRIVE Drive MD)
7.3.2 Drive MD (data description)
1611
Default value
800
Input of response threshold for dn/dt monitoring function.
Caution:
This machine data is required for the load test. It is relevant only for internal Siemens
processes and must not be altered.
1612
Default value
0DBC/FFFF
Input bit field for switching over the appropriate 611D power ON alarm. It is possible to select
one of two shutdown reactions, i.e. pulse disable (bit = 1) or controller disable (bit ˆ =0 =
n ˆ =0 = generator-mode braking), i.e. when the pulse disable reaction is selected, the
set
controller disable reaction is deactivated. The default setting is dependent on the motor type
(FDD ˆ =0D3C, MSD ˆ =FFFF) and is parameterized by the drive configuration during start-up.
Note:
The MSD default setting (FFFF) must be selected when the FDD H option is used.
Caution:
The alarms may be deactivated or concealed through machine data MD 1600 - Concealable
alarms (power ON), i.e. they may be inactive.
