Machine data
2.4 Axis-specific machine data
Description: Activate dynamic stiffness control, if bit is set.
Higher servo gain factors are possible if stiffness control is active
(MD32200 $MA_POSCTRL_GAIN).
Notes:
The availability of this function is determined by the drive used (the drive
has to support the DSC function).
Note on PROFIdrive drives:
Alarm 26017 refers to this machine data if:
a. The PROFIdrive telegram used (see MD13060 $MN_DRIVE_TELEGRAM_TYPE) does
not support the DSC function or does not contain an encoder 1 (such as Tel.
118), to which the DSC scaling for PZD XERR refers. Remedy: Use a suffi-
ciently powerful telegram which also includes encoder 1 (e.g. Tel. 106, 116).
b. Specifically for SINAMICS drives, if inversion of the encoder signal is
parameterized in MD32110 $MA_ENC_FEEDBACK_POL=-1 with active DSC. Remedy:
Remove inversion of the encoder signal from MD32110 $MA_ENC_FEEDBACK_POL, and
enter it in SINAMICS parameter P410 instead.
Description: Configuration of the dynamic stiffness control (DSC):
0: DSC in drive works with indirect measuring system, i.e. motor measuring
system (default scenario).
1: DSC in drive works with direct measuring system.
Notes:
The availability of this function is determined by the drive used (the drive
must support the DSC function).
With SINAMICS (P1193 not equal to 0), the value of this machine data must be
set to 0.
Description: Configuration of compensation dead time of the dynamic stiffness control
(DSC) with optimized PROFIBUS/PROFINET cycle, unit: seconds
