3.10 Digital outputs
Function codes in the following table let you assign different options into logical outputs (terminal [11] and [AL]) on parameters
C021 and C026.
In the same way of that the digital inputs is possible to choose between normally close and normally open and even is possible to
use some On and Off delay for each of the outputs.
3.11 Analog inputs
Two types of external analog inputs are available for frequency reference plus the built-in VR. For voltage input, you can set a fre-
quency from 0 to maximum by applying a voltage from 0 to 10 V between inputs O and L. For current input, apply 4 to 20 mA
between inputs OI and L. Note that voltage and current cannot be input simultaneously. Also, do not connect the signal lines for
inputs O and OI simultaneously.
Switching between the inputs could be done by a digital input setting parameter A005.
Allocate AT (16) to any of the multi-function inputs with the frequency reference set to the terminal block (A001 or A201 = 01).

Function name Description
00 RUN Signal during RUN ON When the inverter is in Run Mode
01 FA1 Constant speed arrival signal ON When output to motor is at the set frequency
OFF When output to motor is OFF, or in any acceleration or deceleration ramp
02 FA2 Over set frequency arrival signal ON When output to motor is at or above the set frequency, even if in acceleration (C042) or
deceleration (C043) ramps
OFF When output to motor is OFF, or at a level below the set frequency
03 OL Overload warning ON When output current is more than the set threshold (C041) for the overload signal
04 OD Excessive PID deviation ON When PID error is more than the set threshold for the deviation signal
05 AL Alarm output ON When an alarm signal has occurred and has not been cleared
06 Dc Disconnection detection ON When the inverter is in trip status
07 FBV PID FB status output ON Shifts output when exceeding the upper limit or falling below the lower limit
08 NDc Network error ON The communication watchdog timer times out
09 LOG Logic operation output ON This function outputs a logic operation result of combination of two functions
10 ODc Not used --
43 LOC Light load detection signal ON Motor current is less than the specified value (C039)
