78 MOVE_CMD Selects the mode of operation (1 byte):
• 0: Absolute position
• 1: Relative position
• 2: Single-speed, continuous positive rotation
• 3: Single-speed, continuous negative rotation
• 4: Manual speed control, positive rotation
• 5: Manual speed control, negative rotation
• 6: Single-speed, continuous positive rotation with
triggered stop (Activation of RPS triggers the stop;
TARGET_POS contains distance to travel after
signal)
