FAQ
1. What is the main function of the Woodward 9907-135 Driver Module?
The Woodward 9907-135 is a driver module designed to control compatible electro-hydraulic liquid valve systems. It receives a control command, processes the feedback signal, and regulates the actuator drive current to provide accurate valve operation in GS3/LQ applications.
2. What power supply does the 9907-135 require?
The module operates from a 10–32 VDC supply, with 24 VDC commonly used as the nominal operating voltage. The power supply should be stable and properly sized for the actuator load because the driver can deliver a high output current during valve operation.
3. What is the maximum output current of the 9907-135?
The 9907-135 provides a maximum drive current of up to 24 A. This high-current output allows the module to operate compatible LQ-series liquid valves and electro-hydraulic actuators that require substantial drive current.
4. What type of control signal does the 9907-135 accept?
The module uses a 4–20 mA control input for command signals. The current-loop signal provides an industrial-standard interface between the control system and driver module and can be used to represent the required valve position or control demand.
5. Which valves are compatible with the Woodward 9907-135?
The 9907-135 is associated with the GS3/LQ range and is used with compatible LQ3, LQ25, LQ25T and LQ Bypass Series liquid valves. The exact valve and actuator combination should be confirmed against the original system configuration before replacement.
6. What is the purpose of the resolver feedback on the 9907-135?
The single-speed resolver provides feedback information to the driver module. This feedback allows the control system to monitor actuator movement and compare the actual response with the commanded position, supporting closed-loop control and more stable valve operation.
7. What should be checked if the 9907-135 does not drive the valve correctly?
First check the DC supply voltage and verify that the 4–20 mA command signal is present and within the expected range. Next inspect resolver wiring and feedback quality, actuator connections, and valve mechanical movement. If the input command and feedback are normal but the output current is incorrect, the driver output stage and protection status should be investigated.
8. What are common causes of a Woodward 9907-135 driver fault?
Common causes include incorrect supply voltage, excessive actuator current, short circuits, damaged resolver wiring, incorrect 4–20 mA input signals, loose terminals, or mechanical problems in the connected valve or actuator. Troubleshooting should begin with the power and signal circuits before testing the actuator and driver output stage.
