Thanks for the clarification. After two posts in the ebike subforum, you finally provided the context that your issue isn’t related to e-bikes. That context would have been really helpful before.
500/48 =10.417A

500/48 =10.4i set it to 13A ,is it dangerous for motor ?
 
Can you state the reason for imposing the limit? That would help with context. Most questions on e wheelchairs are either limiting power to meet a legal restriction, or increasing torque to get up a hill or over a curb, etc.
Is your reason to protect the motor? If so, it’s not an issue. These motors can handle two or three times their rating. It’s only an issue if you plan to run it at 25A all day long, but you are in control of that already, by not riding it full throttle all the time.
