P1-22 Inertia ratio between motor and load (for LTX only)

Setting range: 0.0 – 1.0 – 30.0

The inertia ratio between motor and connected load can be specified in this parameter. This value can usually remain set to the default value "1.0". However, the inertia ratio is used by the control algorithm as precontrol value for CMP../synchronous motors from P1-16 to provide the optimal torque/current for accelerating the load. This is why the exact setting of the inertia ratio improves the response characteristics and the dynamics of the system. For a closed control loop, the value is calculated as follows:

If you do not know the value, keep the default setting "1.0".

Only use in connection with the LTX encoder card.
