6.5.3. 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
Setting Name Description Page
0 Fault Closed when Inverter fault occurs.

1 During running
Closed when either FWD or REV RUN command is input or when the Inverter outputs
voltage.

8 During baseblock Closed when Inverter output shuts OFF.

9 Operation mode Closed when RUN command or frequency reference from Digital Operator is selected.

10
Inverter operation
ready
Closed when no Inverter fault does not occur and the Inverter can be operated.

11 Timer function

52
12 Automatic restart Closed during fault retry operation.

13 OL pre-alarm
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.

14
Frequency reference
loss
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.

15
Output from serial
communication
Activates contact output independently from Inverter operation by a command from serial
communications (MEMOBUS).

16 PID feedback loss
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.

17 OH1 alarm Closed during heatsink overtemperature (Digital Operator displays OH1” blinking).

Factory settings: n040=0, n041=1
