Parameters involved in the calculation of velocity command:
- S.m.p. MAXGEAR1 (P2) = maximum rpm of the first gear = 1000.
- S.m.p. MAXGEAR2 (P3) = maximum rpm of the second gear = 2000.
- S.m.p. MAXGEAR3 (P4) = maximum rpm of the third gear = 3000.
- S.m.p. MAXGEAR4 (P5) = maximum rpm of the fourth gear = 3500.
- S.m.p. MAXVOLT1 (P37) = maximum velocity command for the first gear = 9500.
- S.m.p. MAXVOLT2 (P38) = maximum velocity command for the second gear = 9500.
- S.m.p. MAXVOLT3 (P39) = maximum velocity command for the third gear = 9500.
- S.m.p. MAXVOLT4 (P40) = maximum velocity command for the fourth gear.
= 9500 x 3500 rpm / 4000 rpm = 8312.
Parameters involved in the calculation of position feedback.
- A.m.p. NPULSES (P13) = number of pulses per turn of the encoder = 18000.
- A.m.p. SINMAGNI (P65) = Multiplying factor if the encoder is sinusoidal = 1.
- A.m.p. INPREV1 (P72) = Input revolutions of the first gear =4.
- A.m.p. INPREV2 (P74) = Input revolutions of the second gear =2.
- A.m.p. INPREV3 (P76) = Input revolutions of the third gear =4.
- A.m.p. INPREV4 (P78) = Input revolutions of the fourth gear =1.
- A.m.p. OUTPREV1 (P73) = output revolutions of the first gear =1.
- A.m.p. OUTPREV2 (P75) = output revolutions of the second gear =1.
- A.m.p. OUTPREV3 (P77) = output revolutions of the third gear =3.
- A.m.p. OUTPREV4 (P79) = output revolutions of the fourth gear =1.
Calculation of motor speed for the MAXVOLT of each range (gear):
Motor speed = MAXGEAR x INPREV / OUTPREV
Motor speed with MAXVOLT1 = 1000 x 4 / 1 = 4000 rpm.
Motor speed with MAXVOLT2 = 2000 x 2 / 1 = 4000 rpm.
Motor speed with MAXVOLT3 = 3000 x 4 / 3 = 4000 rpm.
Motor speed with MAXVOLT4 = 3500 x 1 / 1 = 3500 rpm.
