Do you know for a fact that your HAL file is setup correctly?
I only modified m5i20_io.hal file. Below is the config:
# Connect amp enables to motion controller.linksp Xenable =>
m5i20.0.out-03linksp Yenable => m5i20.0.out-04linksp Zenable => m5i20.0.out-10
# Connect amp enables to m5i20 dac enables
linksp Xenable => m5i20.0.dac-00-enable
linksp Yenable => m5i20.0.dac-01-enable
linksp Zenable => m5i20.0.dac-02-enable
Can you switch any of the 7I37 outputs?
Now I am learning this system, therefore I do not have any other outputs to do
connection.
The servo amp specified 5-24V in, so your voltage should be OK, my guess is
that you are not talking to the correct I/O pin in your HAL file
What FPGA card connector is the 7I37 connected to?
The FPGA card is 5I20
Are you using the inverted output to drive the 7I37? (The FPGA pin must be low
to enable the corresponding 7I37 output)
How can I check it?
