OSDK 4.1 Gimbal rotate sync -> strange rattling noise on H20T but not on Z30

Hello,
I'm using a C++ program to control the gimbal. When the Z30 is connected, the movement is smooth without any strange sound. When the H20T is connected, the movement has a rattling sound which doesn't sound good.

Does this moise come from the duration which I typically set to 0s? How to get rid of this rattling sound?
Below you'll find the C++ code of the function.

BR,

Michael

int moveGimbal(GimbalManagerSync *gimbal, string payload_index, int yaw, int roll, int pitch, int mode, int duration, string cam_type, int num_payload, int loggingAvailable)

{

ErrorCode::ErrorCodeType ret;

DJI::OSDK::GimbalModule::Rotation rotation;

float factor_step = 0.1;

rotation.rotationMode = mode;

rotation.pitch = static_cast<float>(pitch)*factor_step;

rotation.roll = static_cast<float>(roll)*factor_step;

rotation.yaw = static_cast<float>(yaw)*factor_step;

rotation.time = duration;

try

{

if (payload_index == "PAYLOAD_INDEX_0")

ret = gimbal->rotateSync(PAYLOAD_INDEX_0, rotation);

else if (payload_index == "PAYLOAD_INDEX_1")

ret = gimbal->rotateSync(PAYLOAD_INDEX_1, rotation);

else if (payload_index == "PAYLOAD_INDEX_2")

ret = gimbal->rotateSync(PAYLOAD_INDEX_2, rotation);

}

catch (...)

{

DERROR("MOVE GIMBAL failed.");

return 0;

}

if (ret != ErrorCode::SysCommonErr::Success)

{

DERROR("MOVE GIMBAL failed.");

ErrorCode::printErrorCodeMsg(ret);

return 0;

}

return 1;

}
