76 VICSION VS500
F9.9 Load self- equilibrium function
F9.10 Load self- equilibrium proportion
F9.11 Trimming range of load self- equilibrium freq
Setting range：0～1
Setting range：0.50～2.00
Setting range：0.0～5.00
These parameters are used for setting load self-equilibrium function ，in linkage synchronous running mode, master
inverter is equals an inverter plus a high-precision synchronizer, usually can get high-precision freq. Synchronous.
In some application field, load of inverter group should keep balanced so that all the transmission chain tension or
velocity strict agreement.
VS500 serial of inverter has loaded self- equilibrium function when inverters are in linkage running mode.
When the load self- equilibrium function is valid, master inverter will transfer the load information to every slave
inverter, and every slave inverter will adjust the load instructions according the master.
When the certain slave inverter should to bear a heavier load, it could change through [F9.10]. The value is
greater, the load capacity is heavier.
Load self- equilibrium below 5Hz, the effect limited. Only if each master and slave inverter has good linkage ratio
coefficient, the self- equilibrium function is valid.
If the adjust is not obvious, please increase parameter [F9.11]
6.11 Special function parameter unit
FC.0 Under voltage protection level
Setting range： 360V ~ 460V
It defines lower limit voltage which terminals P+ and P- are allow while inverter is working normally. For some low
voltage conditions, user can decrease under voltage protection level to ensure that inverter is running normally
FC.1 over voltage limit level
Setting range： 660V ~ 760V
It defines threshold of voltage stall protection while motor is decelerating. If DC voltage caused by decelerating is
beyond setting value of FC.1, deceleration time will automatic prolong. Shown as fig 6-33

FC.2 current amplitude limiting level
Setting range： 150 ~ 200％
It defines the max output current which is permitted by inverter. Whatever the operation mode is, inverter will adjust
output freq. to inhibit current within the range of regulation, when output current of inverter is beyond setting value of
FC.2.
