CompactRIO restart when run VI of NI 9505 and servo motor

[parasolar]

I plan to use NI 9505 to control a servo motor, and the cables are connected according to the manual of NI 9505 (The M+  and M- ports are connected with servo motor directly). I can read the the encoder value from VI, but when I try to control the servo motor by even a very simple VI, the error happens, and the compactRIO restart. When I disconnect the motor and 9505 module, the voltage between the M+ and M- port can be measured, and it  is 24 V. I think maybe the current of motor through the 9505 module is too high, but why and how to solve it. Is there anybody can help me? Thank you very much.

If you believe that your motor pulls more than 5A, take a look at this from the NI 9505 product page. It's the first bullet point.

• Continuous current of up to 5 A at 40 °C (or 1 A at 70 °C) at 30 V - for higher power add NI 9931

The NI 9931 will allow the 9505 to supply up to 7.3A.
