36730 DRIVE_SIGNAL_TRACKING
MD number Detection of additional drive actual values
Default setting: 0 Min. input limit: 0 Max. input limit: 4
Changes effective after POWER ON Protection level: 2/7 unit: -
Data type: BYTE Valid as of software version: 2.1
Meaning: DRIVE_SIGNAL_TRACKING (acquisition of additional drive actual values) informs the NC
which additional drive actual values are transferred in the PROFIDrive message frame and
in which system variables they should be stored.
Encoding:
0: No additional drive actual values
1: The following drive actual values are transferred and stored in the system variables:
actual value, system variable
Utilization, $AA_LOAD
Torque setpoint value, $AA_TORQUE
Power, $AA_POWER
Current actual value, t$AA_CURR
2: The total PROFIDrive message frame is stored in a system variable:
actual value, system variable
PROFIDrive message frame, $VA_DP_ACT_TEL
MD irrelevant for ... ---
