No this will be ok, if it was the other way round then it wouldn't work so good because your motors under full load would demand more current than the board could supply but your motors will only draw 1.7A max and the board can supply 2.2 if needed.

Edit: No scrap that I've just spotted there 2.4A wired Bi-parallel so your on dodgy ground.!!


Regards the motors they are 5 phase motors and ripping out the control would probably mean new motors as well because most modern drives only work with 2 or 4 phase motors.? . . . Luckly motors are cheap.!
