You need to find the Error codes otherwise you'll never guess. But I if had to take an educated guess I'd say it relates to acceleration or deacceleration ramp up/down times which are common errors.
If they are set too short then you'll get over current or voltage errors because it cannot possibly accelerate to commanded speed in short periods but the drive will try it's best to do so and dump in volts or current which then trips in the protection. Same goes for deacceleration.

The error codes will give an indication where to look.
