3. Channel 1~4 Schematic
The reference voltage(ref) is given externally through pin21.
The input OP-amp output signal is amplified by (20K/10K) times and then fed to the power amplifier. The gain of power amplifier is
4 so the total max gain of channels 1 through 4 is 8.
4. Mute Inputs
FAN8741 has 2 independent mute pins: Pin #22(MUTE1) and Pin #23(MUTE2). Details are shown below.
Note:
To make the spindle short brake, MUTE2 goes low and the spindle command must not be in deadzone(±50mV). When the spindle
command is within the deadzone, the spindle block enters disable mode even though MUTE2 is low.
