Setting Functions Descriptions
21 Low voltage detection The corresponding output will be closed when
the DC Bus voltage drops below our threshold.
The keypad will display “Lu”.
22 Operation Mode indication The corresponding output will be closed when
the AC drives “Operation Command” is
controlled by the external terminals.
23 Fault Indication The corresponding output will be closed when
AC drive has experienced a fault.
24 Master Frequency Attained 1 The corresponding output will be closed when
the AC drives output frequency exceeds
(Pr.03-08) Master Frequency Attained 1.
25 Master Frequency Attained 2 The corresponding output will be closed when
the AC drives output frequency exceeds
(Pr.03-09) Master Frequency Attained 2.
26 Over Temperature indication The corresponding output will be closed when
the AC drive temperature exceeds its rating.
27 Drive Ready The corresponding output will be closed the
when the AC drive is ready and has no faults.
28 External Emergency Stop (EF1) The corresponding output will be closed when
multi-function input terminals (Pr.04-00 to
04-07) are set to emergency stop and then
activated.
29 Software brake output The corresponding output will be closed when
the AC drives DC bus voltage exceeds
(Pr.08-19) the brake level.
30 OL or OL1 overload warning The corresponding output will be closed upon
an overload (OL or OL1) fault.
31 Dwell indication (sleep) The corresponding output will be closed when
the AC drive is in a Dwell status (Pr.11-07).
32 Low current indication The corresponding output will be closed when
the AC drives output current is lower than the
Low Current setting (Pr.06-08).
33 PID feedback error indication The corresponding output will be closed when
the PID feedback signal has an error.
34 PLC Program Running
The Output will be activated when PLC
Program is running.
35 PLC Program Step Completed
The Output will be activated for 0.5 sec when
each multi-step speed is attained.
36 PLC Program Completed
The output will be activated for 0.5 sec when
the PLC program cycle has completed
37 PLC Operation Paused
The output will be activated when PLC
operation is paused.
The VFD-F has two form C relays (multi-function output 1 and 2). There is an optional
External Relay Card with 6 NO contact relays (multi-function outputs 3-8).
