Appendix Ⅲ Description on proportion linkage function
(this function available in C2.08 and above)
Ⅲ-1.Function
Proportional linkage master:
Communication address of master =248
Proportional linkage slave:
Communication address of slave =1 to 247
If you want to use proportion linkage function, master parameters setting as
follows:
F9.00
Baud rate
F9.01
Data format
F9.02
This unit address
Slave parameters setting as follows
F9.00

Proportional
FC.01
coefficient
Slave output frequency = Master setting frequency * Proportional linkage
coefficient + UP/DOWN Changes.
Ⅲ-2.Examples of proportion linkage function:
Functions provided by proportional linkage system:
1. Master adjusts system speed via AI1 and controls FRW/REV run by using
terminals;
2. Slave runs following mater, the proportional linkage coefficient is 0.90;
(when it is powered on, master displays 50Hz, and slave displays 45Hz)
3. Slave receives the running speed command from master and save it into
F0.01.
4. The actual setting frequency of slave can be fine-tuned by the operation
of rising and falling of keypad or terminals.
5. The actual setting frequency of slave can be fine-tuned by the analog AI2
too.
6. The actual setting frequency of slave = F0.01 + slave AI2 analog
trimming + UP/DOWN Changes.
