7 Drive Machine Data (SIMODRIVE Drive MD)
7.2.2 FDD MD (data description - SW 3)
1219
Default value
3 999.0
Input of block frequency for current setpoint filter 4 (band-stop). When block frequencies of
< 10 Hz are input, the filter is deactivated (proportional element with a gain of 1). The filter is
activated via machine data MD 1200 and MD 1201.
Note:
The maximum block frequency input value is limited by the sampling frequency of the control
(MD 1000) (parameterization error).

MD 1000 = T
1220
Default value
100
Input of 3dB bandwidth for current setpoint filter 4 (band-stop). The filter is activated in
machine data MD 1200 and MD 1201.
Note:
When 0 is entered for the bandwidth, the filter is parameterized as a proportional element with
a gain of 1.
1400
Default value
1 500
Input of motor rated speed as specified on the motor data sheet (non-Siemens motor) or
automatic parameterization using machine data "Motor code number" (MD 1102).
1401
Default value
1 500
Machine data MD 1401 defines the maximum operational speed of the feed motor. It is used
as a reference value for the speed setpoint interface and for the machine data "Monitoring
speed motor" (MD 1405). Its default value is set by means of motor selection (MD 1102) to
the rated motor speed as specified on the motor data sheet.
