AASD servo not reaching full rpm in speed mode.

[rschwarz]

I have a Chinese aasd servo drive and motor (80st-m04025) that i run on 110v in speed mode.

My problem: even at full 10v input signal the motor only reaches 2000rpm Max.
Also in manual jog mode it only reaches 2000rpm
(Rules out input voltage issue)

My parameters:
Pn02: speed mode
Pn159: 300 (should give 3000rpm at 10v input)
Pn168: external analog voltage

Is it because I run on 110v?
Any suggestions are appreciated.

Thank you,
Rob

Most likely there is a Maximum Speed parameter that is set to 2000 RPM.

Check pulley settings in your cnc program also.

Yes it could be 120v supply voltage, it will give you less RPM unless the Drive is rated /setup for that Voltage, the other thing to look at is the electronic gearing in the drive, ( if it has it ) this to can give you a low output if not set correct
