Hi,
I’m planning a system which will need to be redundant, that means that if a problem will cause the motor driver to fry I would need to switch (either automatically or manually) the motor to be used with a spare motor controller.
I have tested my motors successfully with VNH5019 drivers and was wondering what sould I switch and will it have any implications on the health of the motor, the driver or the power supply.
Should I:
a. switch the power supply between the drivers? (and connect the motor wires in parallel to both drivers)
b. switch both motor wires? (and power two drivers at once (even though one has it’s motor leads disconnected)
c. switch both power and motor leads?
I would love to hear your thoughts about this issue.
Thanks,
Ziv
