828D + S120 Combi + 1PH8133. Maximal speed.

Hello.

I use such system config: 828DBasic T + S120 Combi (6SL3111) + 1PH8133 (as spindel motor).

During commissions steps I have such parameters auto written:

p300[0] 1PH8 induction motor
p301[0] 10811
r302[0] 10811
r303[0] 0
p304[0] 361 V
p305[0]28.2 A
p306[0] 1
p307[0] 13.5 kW
p310[0] 40.1 Hz
p311[0] 1150 rpm

With this parameters I can reach 1265 rpm for motor (r22) and 42Hz (r24). r25 = 326V.

According  to motor parameters it can operate at maximal speed 8000 rpm. In my situation maximal motor speed must be 4500 rpm. I trying change p310 parameter to 150 Hz without success.

Is it possible setup drive for non-nominal motor parameters (for example 150 Hz and 4500 rpm)?

Hello KuzemkoA,

Please check 828D machine data spindle axis MD 32260 value, set it to 4000 RPM as per your requirement, retaining other parameter values as it is & check if you get the required speed.

 32260=4500. p1082[0]=8000. And I cant ger requried speed. Also I set maximum speed for my gear stage.

Hello KuzemkoA,

What are the values in P2000[0], P2001[0], r0313[0], r0070[0]?

Have you carried out automatic calculation by setting P0340? (Ofcourse prior to commissioning with 828D system)

 P2000[0]=1150.0 P2001[0]=1000 r0311[0]=1150.0 r70=530.0. Automatic calculation P0340 not run.

Set P2000[0] = 4500

P2001[0] = 361

Save parameters, switch OFF & ON power supply & check.

 Now it work. Thank you.
