Start-Up And Stop Control - Salicru CV50-008-4F User Manual

Note:
1. Set the motor parameters according to the name plate of the motor.
2. During the motor autotune, de-couple the motor from the load if rotation autotune is selected to make the
motor stay in a static and empty state, otherwise the result of autotune is incorrect. The asynchronous motors
can autotune the parameters of P02.06~P02.10.
3. During the motor autotune 1, do not de-couple the motor from the load if static autotune is selected.
Because only some parameters of the motor are involved, the control performance is not as better as the
rotation autotune. With autotune 1, CV50 inverters can calculate the parameters from P02.06 to P02.10.
4. During the motor autotune 2, do not to de-couple the motor form the load if static autotune is selected.
Because only some parameters of the motor are involved, the control performance is not as better as the
rotation autotune. With autotune 2, CV50 inverters can calculate the parameters from P02.06 to P02.08. It is
suitable in the cases which SVPWM control is applied.

7.6 Start-up and stop control

The start-up and stop control of the inverter includes three states: start after the running command during
normal powering on, start after the restarting function becomes valid during normal powering on and start after
the automatic fault reset. Below is the detailed instruction for the three types of starting.
There are three starting modes for the inverter: start from the starting frequency directly, start after the DC
braking and start after the rotation speed tracking. The user can select according to different situations to meet
their needs.
For the load with big inertia, especially in the cases where the reverse rotation may occur, it is better to select
starting after DC braking and then starting after rotation speed tracking.
1. The starting logic figure of starting after the running command during the normal powering on
2. The starting logic figure of starting after the restarting function becomes valid during the normal powering on
