hi

I am running 1fk7062-2ac71-1ub0  servo motor .

I can see that  Max. permissible speed (mech.) = 7200 rpm ,

1. why I need this data ?

I can see also that  with  recommended inverter connected  

Maximum permissible speed (converter)=3200 rpm

in my topology   I am using ALM , and book size motor module .

1. is there a possibility to go up to 4000 rpm  in my configuration ?

thanks

hi

ok the max speed with inverter is 3200 rpm .

but  why do you concern about the duty cycle ?

with RMS toque I am bellow the s1 curve , I need more speed .

ok!

now we are talking , how can I do it with sinamics s120 ?

opening the speed limit gives me faults !

can you help me ?

ok!

 What is fault code? Which CU? Which is control mode? Needs more details. 

CU320-2 PN

ACTIVE LINE MODEULE 16KW  + ACTIVE INTERFACE MODULE

MOMO- 5A

 do not remember the alarm code !

thanks

Hello,

Please provide the detail description of problem. Have you commissioned the drive & motor? When this fault displayed? Which is fault code? Which is control mode? How commands & inputs are provided etc.

I think duty cycle have affected load within speed and torque's characteristics.

speed and torque's characteristics have Constant torque.

In ther case of over Constant torque area, It's Constant power.

So, you have to bring duty cycle within this  characteristics curve.

Maximum speed also have to bring duty cycle within constant power's chracteristic curve.

If it is out load duty cycle, moter lifecycle will be reduced.
