Using Output Signals (n040, n041)
Multi-function contact output Terminals MA, MB and M1 functions can be changed when necessary by setting constants
n040 and n041.
•
Terminal MA and MB functions: Set to n040.
•
Terminal M1 function: Set to n041.

Table 16 Multi-Function Output Variables
Closed when Inverter fault occurs.
Closed when either FWD or REV RUN command is input or when the Inverter outputs
voltage.
Closed when Inverter output shuts OFF.
Closed when RUN command or frequency reference from Digital Operator is selected.
Closed when no Inverter fault does not occur and the Inverter can be operated.
Closed during fault retry operation.
Outputs an alarm before Inverter and motor overload protection are enabled. Pre-alarm level
is 150% for 48 seconds for the Inverter and more than 80% of the overload protection time for
the motor.
Outputs a contact when detecting a rapid decrease in the frequency reference. A rapid
decrease in the frequency reference means that the reference value is reduced more than
90% within 400ms when the reference is input to control circuit terminal.
Activates contact output independently from Inverter operation by a command from serial
communications (MEMOBUS).
Detects a rapid decrease in feedback and outputs a contact when the PID Control mode is
set. Detects when the feedback value decreases less than the detection level (n093) for
longer than the feedback loss detection delay time (n094); the Inverter continues operation.
Closed during heatsink overtemperature (Digital Operator displays OH1" blinking).
