Applies the supply voltage of the pre-drive unit. When VGOFF="L", the voltage on the booster circuit is
output to this terminal and it becomes the direct supply voltage of the pre-drive unit.
Applies the analog-signal supply voltage.
Input terminals on forward/reverse sides of CH3(digital input).

MUTE terminal at CH1, 2, and 4. MUTE ON with "L".
Input terminals on the forward/reverse side of CH3(digital input).
Input terminals on the forward/reverse side of CH3(digital input).
Power GND.
Output terminal on the reverse side of CH1.
Power supply in the output section of CH1.
Output terminal on the forward side of CH1.
Power GND.
Output terminal on the reverse side of CH2.
Power supply in the output section of CH2.
Output terminal on the forward side of CH2.
Power GND.
Input terminals on the forward/reverse side of CH2(digital input).
Input terminals on the forward/reverse side of CH2(digital input).
Power connection terminal in the output section that monitors the half of the power supply to the output
section. It monitors the output power with the digital servo to correct its dependency on the voltage.
Power connection terminal in the output section.
START/STOP terminal. Starting with "H" and stopping with "L".
Signal GND.
Applies the logic-signal supply voltage.
Switching terminal on the booster circuit
Terminal to which the rectifying transistor on the booster circuit is connected.
Switching terminal on the booster circuit
Terminal to which the rectifying transistor on the booster circuit is connected.
ON/OFF switching terminal on the booster circuit. Booster circuit ON with "L". Booster circuit OFF with "H".
Input terminals of the forward/reverse side of CH4(digital input).
Input terminals of the forward/reverse side of CH4(digital input).
Power GND
Output terminal on the forward side of CH4.
Power supply in the output section of CH4.
Output terminal on the reverse side of CH4.
Power GND.
Output terminal on the forward side of CH3.
Power supply in the output section of CH3.
Output terminal on the reverse side of CH3
Power GND
