    7.5 Parameters of the motor  Physical accident may occur if the motor starts up suddenly during autotune. Please check the safety of surrounding environment of the motor and the load before autotune.  The power is still applied even the motor stops running during static autotune. Please do not touch the motor until the autotune is completed, otherwise there would be electric shock.

  • Page 89: Start-Up And Stop Control

    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.

  • Page 95: Pulse Counter

    Control short vibration A short vibration period with the same value as the derivation time (Td) means that the derivation time is strong. Shortening the derivation time (Td) can control the vibration. Setting the derivation time as 0.00 (it means no derivation control) is useless to control the vibration, so the solution is to decrease the gain. 7.11 Pulse counter CV50 inverters support pulse counter which can input counting pulse through HDI terminal.
