i950 TA Cia402 Advanced: actual speed value from position encoder (0x503F:11=[1]): e.g. in case of beam interruption at the laser measurement system uncontrolled drive behaviour may occur (corrected from V01.08.00)
Corrected from:
Servo inverter i950 with TA CiA402 Advanced: TA-i900 from FW 01.08.00
Library: L_MC1P_MotionControlBasic: from V03.29.00
Response of the new version:
In the event of a beam interruption occurring at the laser measurement system, the tracking error monitoring is triggered in the motion axis and an application quick stop (QSP application) is executed as an error reaction.
With QSP application, the actual speed of the drive is used as the initial speed (start value). However, since no plausible actual value is available in the described constellation, the stop ramp begins with a setpoint speed that is much too high, resulting in an apparently uncontrolled drive movement.
What happens?

When does the behaviour occur?
Servo inverter i950 with TA CiA402 Advanced and
SSI linear encoder as load encoder
0x503F:11 (Source of ActVelocity 0x606C) = "PositionFeedback"
Which products are affected?
Servo inverter i950 with TA CiA402 Advanced (0x4000 = TA CiA402 Advanced [1])
