This MD can also be used for "simple" drives that have drift problems due to drive-
internal implementation as analog drives. To avoid erroneous settings, this static
drift compensation only
becomes active with PROFIdrive if MD32250 $MA_RATED_OUTVAL !=
0 (i.e. the MD has no effect in the case of automatic interface adjustment between the
NC and the drive).
Note:
Drift compensation must not be active if the DSC function (MD32640
$MA_STIFFNESS_CONTROL_ENABLE=1) is being used, otherwise unexpected speed
oscillations will occur when DSC is enabled/disabled.
Standardization: The input value is related to the corresponding interface
standardization in
MD32250 $MA_RATED_OUTVAL,
MD32260 $MA_RATED_VELO, and
MD36210 $MA_CTRLOUT_LIMIT.

Description: MD36730 $MA_DRIVE_SIGNAL_TRACKING = 1 activates the acquisition of the following drive
actual values (if they are made available by the drive):
● $AA_LOAD Drive load
● $AA_POWER Drive active power
● $AA_TORQUE Drive torque setpoint
● $AA_CURR Smoothed current setpoint (q-axis current) of drive
MD36730 $MA_DRIVE_SIGNAL_TRACKING = 2 activates the acquisition of the following drive
actual values:
With PROFIdrive, it must be ensured that the stated values are also transmitted in the
drive
actual
message
frame (provide sufficient message frame length on the bus, assign
the values to the message frame content in the drive, e.g. use message frame 116).
● $VA_DP_ACT_TEL shows actual value message frame words
Note: Values 3 and 4 are reserved
Note: The value range of MD36730 $MA_DRIVE_SIGNAL_TRACKING can be restricted because
of reduced functions of control systems
