Analog input and output parameter group02
PARAMETER DESCRIPTION 112
PT100 is input through analog voltage, and the voltage input range of 2-5/4-5 is set to 0-10V (02-08(P.73)=1;
02-20(P.17)=1; please note that the voltage/current switch on the keypad is set to the voltage input position). Set
analog voltage input for PT100 function (02-00(P.500),02-01(P.501) are set to 12).
When the inverter is running and PT100 input voltage is higher than 02-55(P.592) value, inverter output frequency
will decrease to 02-57(P.594) set frequency after 02-58(P.595) set time.
When PT100 voltage is higher than 02-56(P.593), inverter will operate according to the settings of 06-15 (P.533).
5.3.14 FM calibration parameter
It is used to adjust the analog voltage level that terminal FM outputs.
FM calibration parameter
Output of terminal HDO with FM function can be shown as follows:
2300Hz
0
1440Hz
FM Pulse frequency
Corresponding to 100% of the
function set by 02-44P.543
Terminal HDO needs to be calibrated due to differences in components, voltage/current calibration includes the
following steps:
1. Link an electric meter with 1mA scale or a high speed counter across terminal HDO and terminal SD. Wire as
following figure , and set 02-51(P.55) to 60Hz,02-44(P.543) to 0.
2. Start the motor and set output frequency 60Hz.
3. When the motor runs steadily, read out 02-59(P.187) value. Display will show FM calibration value. Turn to
increase and adjust 02-59(P.187) value. Press for more than 1 second, and the pointer will move
upward.Turn to decrease and adjust 02-59(P.187) value. Press for more than 1 second and the
pointer on the meter will move downward.
