L_MC1P: Quickstop application behaves differently to QSP in the drive controller (fixed as of V03.18.00)
Corrected from: Library: L_MC1P_MotionControlBasic (FAST Motion) from V03.18.00.252 (Update via Package-Manager)
Response of the new version:
Quickstop-Application: For drift-free standstill, the system now switches to position control only when the actual speed value has reached standstill (0 rpm) in addition to the speed setpoint.
What happens?
Quickstop Application: If an extremely long QSP delay is set (drive cannot follow), the drive may oscillate. The reason for this is that the system already switches to position control if only the speed setpoint has reached standstill and not also the actual speed value.
When does the behaviour occur? An extremely long deceleration (sub-index 48 and sub-index 49) is set for the Quickstop application function, so that the drive cannot follow the specified ramp.
Which products are affected: Library: L_MC1P_MotionControlBasic (FAST Motion)
Short-term measures, Evaluation/Recommendation: Parameterize the deceleration ramps of the Quickstop application (Subindex 48 and Subindex 49) so that the drive controller can bring the motor to a standstill on the ramp in a controlled manner.
