F05 Running control mode
Select this function, the slave inverter will follow the command of host inverter
to run.
After select this function, it can also use keyboard, terminal and RS485 to
control the slave inverter‟s running.
In the proportion of linkage during operation, if control by the keyboard,
terminal,RS485 control, once the slave inverter stopped, the slave will N longer
respond to the host command, if need the slave once again to respond to host
commands, it should control through the keyboard, terminal and RS485, or after the
host sends cease and desist commands then the slave will respond the command again
to run.

A55 Proportional linkage factor
During the proportional of linkage, the running state of slave inverter is controlled by the host
inverter.
Slave inverter F01 = proportional factor*the actual set frequency of host inverter of proportion
linkage.
II-2.
Slaver S00 actual set frequency = slave F01 + frequency give and secondary amend
+ascend/descend adjusting.
Features of proportional function:
1: The host inverter using the potentiometer to control the system speed and use the terminals
to control the forward/reverse running.
2: The slave follows the host running, the proportional linkage factor is 1.00
3: After get the running speed command from host inverter, the slave will store this command
into to F01.
4: The slave actual frequency is set through the keyboard or through terminal ascend/descend
adjusting.
5: The slave actual frequency is set through potentiometer adjusting.
