Chapter 8 Applied Functions
If 6V is being input into V1, the frequency corresponding to 10V is 60Hz, so the auxiliary speed A in the table below
is 36Hz(= 60[Hz]x(6[V]/10[V])) or 60%(=100[%]X(6[V]/10[V]) according to the condition.
Setting Type Final Command Frequency
0 M[Hz]+(G[%]*A[Hz]) 30Hz(M)+(50%(G)x36Hz(A))=48Hz
1 M[Hz]*(G[%]*A[%]) 30Hz(M)x(50%(G)x60%(A))=9Hz
2 M[Hz]/(G[%]*A[%]) 30Hz(M)/(50%(G)x60%(A))=100Hz
3 M[Hz]+(M[Hz]*(G[%]*A[%])) 30Hz(M)+(30[Hz]x(50%(G)x60%(A)))=39Hz
4 M[Hz]+G[%]*2*(A[%]-50[%])[Hz] 30Hz(M)+50%(G)x2x(60%(A)–50%)x60Hz=36Hz
5 M[HZ]*(G[%]*2*(A[%]-50[%])) 30Hz(M)x(50%(G)x2x(60%(A)–50%))=3Hz
6 M[HZ]/(G[%]*2*(A[%]-50[%])) 30Hz(M)/(50%(G)x2x(60%–50%))=300Hz
7 M[HZ]+M[HZ]*G[%]*2*(A[%]-50[%]) 30Hz(M)+30Hz(M)x50%(G)x2x(60%(A)–50%)= 33Hz
*If the set frequency is converted into rpm, Hz above changes into rpm.
Example 2) main speed (M) setting (DRV-07): Keypad (when the frequency command is set at 30Hz)
- maximum frequency (Max Freq)setting)DRV-20): 400Hz
- auxiliary speed (A)setting (BAS-01): I1
(expresses in auxiliary speed[Hz] or percentage[%] according to the condition)
- auxiliary speed gain (G)setting(BAS-03): 50%, IN01~32: default value
If 10.4mA is being input into I1, the frequency corresponding to 20mA is 60Hz, so the auxiliary speed A in the table
below is 24Hz(=60[Hz]x((10.4[mA]-4[mA])/(20[mA]-4[mA])) or 40%(=100[%]x((10.4[mA]-4[mA])/(20 [mA]-4[mA])).
Setting Type Final Command Frequency
0 M[Hz]+(G[%]*A[Hz]) 30Hz(M) + (50%(G) x 24Hz(A)) = 42Hz
1 M[Hz]*(G[%]*A[%]) 30Hz(M)x(50%(G)x40%(A))=6Hz
2 M[Hz]/(G[%]*A[%]) 30Hz(M)/(50%(G)x40%(A))=150Hz
3 M[Hz]+(M[Hz]*(G[%]*A[%])) 30Hz(M)+(30[Hz]x(50%(G)x40%(A)))=36Hz
4 M[Hz]+G[%]*2*(A[%]-50[%])[Hz] 30Hz(M)+50%(G)x2x(40%(A)–50%)x60Hz=24Hz
5 M[HZ]*(G[%]*2*(A[%]-50[%])) 30Hz(M)x(50%(G)x2x(40%(A)–50%))= -3Hz(reverse)
6 M[HZ]/(G[%]*2*(A[%]-50[%])) 30Hz(M)/(50%(G)x2x(60%–40%))= -300Hz(reverse)
7 M[HZ]+M[HZ]*G[%]*2*(A[%]-50[%]) 30Hz(M)+30Hz(M)x50%(G)x2x (40%(A)–50%)= 27Hz
Example 3) main speed setting (DRV-07): V1 (if the frequency command is set at 5V and 30Hz)
- M[HZ]ax Freq (DRV-20): 400Hz
- auxiliary speed (BAS-01): I1 (expresses in auxiliary speed[Hz] or percentage[%] according to the condition)
- auxiliary speed gain (BAS-03): 50% (represents G in the table below. The value is 0.5)
- IN01~32: default value
