Are the Zapp 3NM steppers good with their PM-752 drivers?

We sell the PM752 with the SY60 and they work well together.
Also 72V is a bit too high for the PM752 driver, it will work, but is a bit close to the max voltage.
At a high voltage the Arc motor should perform well, but will not spin as fast as the Sy60, but will have a lot more torque at the slower speeds.
I would also point out that the datasheet is wrong, and if connected in parallel the current would be 6A not 4.2.
It is odd that they say the motor is rated as 4.2A in parallel because parallel current would be double the series current.
All i can think of is that the motor has a problem running at 6A, so if you decide to use this motor, i would ask the question to them.
