Analog input and output parameter group 02
PARAMETER DESCRIPTION 122
5.3.3 Proportional linkage gain

This function is used to multiply frequency command from external analog input terminal. When multiple inverters are
running in proportion, it is effective to use this function to fine-tune the frequency command from master inverter to
slave inverter.


When output frequency is lower than 01-01(P.2), it is equal to lower limit frequency 01-01(P.2).
When output frequency is higher than 01-00(P.1), it is equal to upper limit frequency 01-00(P.1).

After multiplying the setting frequency by 02-06(P.185) value, add and subtract can be performed as follows:
For example: When the set frequency is 50Hz, 02-06(P.185)=50% and the external analog input signal is 0~10V.

0V 5V 10V

In the above figure,when 0V is given, the target frequency is 50Hz - (50Hz × 50%) = 25Hz;
when 5V is given, the target frequency is 50Hz - (50Hz × 0%) = 50Hz;
when 10V is given, the target frequency is 50Hz + (50Hz × 50%) = 75Hz.
Note: 1. For proportional linkage signal input, please refer to the description of parameter 02-07 (P.240).
2. When use terminal 4-5 analog (voltage/current) signal as proportional linkage signal input terminal, please
refer to parameter 02-20(P.17); for the setting of external analog signal frequency range, please refer to
parameter 02-09(P.38), 02-21(P.39), 02-30(P.508), 02-20(P.17), 02-08(P.73), 02-29(P.531).
