The K
● MD32200 POSCTRL_GAIN (K
Note
To adapt the input/output unit of the K
the following machine data is assigned pre-assigned:
• MD10230 SCALING_FACTORS_USER_DEF[9] = 16.666667
• MD10220 SCALING_USER_DEF_MASK = 'H200'; (bit no. 9 as hex value).
When entering the K
control loop is still dependent on other parameters of the controlled system (speed setpoint
alignment).
These factors include, among others:
● MD32260 RATED_VELO
● MD32250 RATED_OUTVAL
● Automatic interface alignment (SINAMICS parameter "Reference speed" p2000)
For drive optimization see Further optimization options (Page 207)
NOTICE
Machine axes that interpolate one with another must have the same dynamic response at
the same velocities.
This can be achieved by setting the same K
following machine data:
• MD32900 DYN_MATCH_ENABLE
• MD32910 DYN_MATCH_TIME
The real K
• e.g., HMI Advanced: Operating area "DIAGNOSIS" > Service displays > Service axis.
