L_MC1P_BrakeTest: When using a load sensor, slipping of the brake is not always detected (corrected from V03.21.00)
Corrected from: Library: L_MC1P_MotionControlBasic (FAST Motion) from V03.21.00.102
(Update via Package-Manager)
L_MC1P_MotionControlBasic (FAST Motion) from V03.20.01.01 (Preliminary version)
This version is only made available in agreement with Lenze and for individual cases only.
Update via manual installation of the new library version and integration into the project using placeholders.
Response of the new version:
The brake test function now also works as expected when using a load sensor.
What happens?
L_MC1P_BrakeTest: When using a load encoder (SlotB) as position feedback, a movement of the motor shaft may be detected too late or not at all.
When does the behaviour occur?
i950 with TA CiA402-Advanced and using the load encoder (SlotB) as position feedback. The determined actual values of load encoder and motor encoder can differ from each other, among other things due to the mechanical arrangement, different standardizations and gear factors, which can cause the behaviour described.
Which products are affected?
Library: L_MC1P_MotionControlBasic (FAST Motion)
Short-term measures, Evaluation/Recommendations
Workaround:
Activate the motor encoder for the duration of the brake test function and switch back to the load encoder once the brake test is complete.
Notice: The preliminary version of the 'L_MC1P' library is only intended for short-term remedy in existing systems. If the brake test function is used and the described workaround is not considered sufficient. If necessary, please contact the responsible Lenze sales company.
