Dynaixel Wizard does not allow changing the operating mode while the torque is on. To change the operating mode one must first turn off the torque.
Is this the same also while using the SDK?
While programming DXL Pro via DXL Pro SDK, I would like to change the operating mode from Position Control to Velocity Control by changing the value of relevant control table item.
Can I do this while the torque is on?
The EEPROM area of Dynamixel will be locked when Torque is enabled so it will not allow you to change the Operating Mode.
This is inherited feature from Dynamixel and does not have to do with SDK.
Please refer to Torque Enable of the eManual.
