Heavy axis motion due to too high drive torque or force generation during commutation setting.
External forces or torques cause axis to move out of allowed actual position value range.
Cogging force or torque causes axis to move out of allowed actual position value range.
Reduce value contained in ‘P-0-0506, Amplitude for angle acquisition’ – and / or – Increase value contained in ‘P-0-0507, Test frequency for angle acquisition’
Check mechanical axis system for occurrence of external forces, e.g. due to trailing cable installation, vertical load etc.
Make sure that, during commutation setting by means of sine-wave method, cogging forces of motor do not cause position limits to be exceeded near limits of actual position value range
