LSIS G100, Operation Manual

Page: 125 / 343

V1 is Main Frequency and I2 is Auxiliary Frequency
•
Main frequency: V1 (frequency command setting to 5 V and is set to 30 Hz)
•
Maximum frequency setting (dr.20): 400 Hz
•
Auxiliary frequency (bA.01): I2[Display by percentage (%) or auxiliary frequency (Hz)
depending on the operation setting condition]
•
Auxiliary reference gain (bA.03): 50%
•
In.01-32: Factory default output
Example: an input current of 10.4 mA is applied to I2, with the frequency corresponding
to 20 mA of 60 Hz. The table below shows auxiliary frequency A as 24
Hz(=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])}.

0 M[Hz]+(G[%]*A[Hz]) 30 Hz(M)+(50%(G)x24 Hz(A))=42 Hz
1 M[Hz]*(G[%]*A[%]) 30 Hz(M)x(50%(G)x40%(A))=6 Hz
2 M[Hz]/(G[%]*A[%]) 30 Hz(M)/(50%(G)x40%(A))=150 Hz
3 M[Hz]+{M[Hz]*(G[%]*A[%])} 30 Hz(M)+{30[Hz]x(50%(G)x40%(A))}=36 Hz

* M: Main frequency reference/ G: Auxiliary reference gain (%)/ A: Auxiliary
frequency reference (Hz or rpm) or gain (%)
Note
When the maximum frequency value is high, output frequency deviation may result due to
analog input variation and deviations in the calculations.
5.2 Jog Operation
The jog operation allows for a temporary control of the inverter. You can enter a jog
operation command using the multi-function terminals.
The jog operation is the second highest priority operation, after the dwell operation. If
a jog operation is requested while operating the multi-step, up-down, or 3-wire
operation modes, the jog operation overrides all other operation modes.
