FUNCTION CODES
Chap 5
■ Frequency arrival AND frequency detected – “FARFDT” (Function code data = 87)
The FARFDT, which is an ANDed signal of FAR and FDT, comes ON when both signal conditions are met.
( Function codes E30 to E32)
■ Torque detected 1 – “TD1” (Function code data = 46),Torque detected 2 – “TD2” (Function code data =
47)
This output signal TD1 or TD2 comes ON when the torque value calculated by the inverter or torque command
exceeds the level specified by E78 or E80 (Torque detection (Level)) for the period specified by E79 or E81
(Torque detection (Timer)), respectively. (minimum width of the output signal: 100 ms)
( Function codes E78 to E81)
■ Motor 1, and 2 selected – “SWM1” and “SWM2” (Function code data = 48 and 49)
The output signal “SWM1” or “SWM2” comes ON corresponding to the motor selected by the signal “M2” or the
selected function code group. ( Function code A42)
■ Running forward – “FRUN” (Function code data = 52) Running reverse – “RRUN” (Function code data
= 53)
Output signal Assigned data Running forward Running reverse Inverter stopped
“FRUN” 52 ON OFF OFF
“RRUN” 53 OFF ON OFF
■ Under remote mode – “RMT” (Function code data = 54)
This output signal comes ON when the inverter switches from local to remote mode.
For details of switching between remote and local modes, refer to Chapter 3 “3.3.7 Remote and local
modes.”
■ Motor overheat detected by thermistor – “THM” (Function code data = 56)
When the PTC thermistor on the motor detects an overheat, the inverter turns this signal ON and continues to run,
without entering the alarm
0h4
state. This feature applies only when H26 data is set to “2.”
( Function codes H26 and H27)
■ Brake control – “BRKS” (Function code data = 57)
This signal outputs a brake control command that releases or applies the brake. ( Function codes J68 to J72)
■ Terminal [C1] (C1 function)wire break detected – “C1OFF” (Function code data = 59)
This output signal comes ON when the inverter detects that the input current to terminal [C1] (C1 function) drops
below 2 mA interpreting it as the terminal [C1] wire broken.
■ Speed valid -- “DNZS” (Function code data = 70)
This output signal comes ON when the reference speed or detected one exceeds the stop frequency specified by
function code F25. It goes OFF when the speed is below the stop frequency for 100 ms or longer.
Under vector control with speed sensor, F38 switches the decision criterion between the reference speed and
actual speed. Under vector control without speed sensor, the reference speed is used as a decision criterion.
Function codes F25 and F38.
