No idea what those numbers mean, not everyone here knows every one of the thousands of video cameras that have ever been made. Mfr and vintage would help, especially for those of us who refuse to bother to keep track of anything other than our own machines.
180 is the shutter angle, it controls the motion blur, not the number of frames.
Shooting slow motion is a question of OVER-cranking, not under-cranking. You must shoot more frames per second than your intended playback video system supports. I have no idea if your cameras will do that. Open the manuals to find out.
If you can shoot 60 frames per second and drop it into a 30fps sequence, it will look great played back at 30. It will look normal if you put it into a 60fps sequence.
