Terminal name
1 changeover contact output that indicates that an
inverter's protective function has been activated and the
outputs are stopped.
Fault: discontinuity across B and C (continuity across A
and C), Normal: continuity across B and C (discontinuity
across A and C)
The output is in LOW state when the inverter output
frequency is equal to or higher than the starting
frequency (initial value: 0.5 Hz). The output is in HIGH
state during stop or DC injection brake operation.
The output is in LOW state when the inverter output
frequency is equal to or higher than the preset detection
frequency, and is in HIGH state when it is less than the
preset detection frequency.
Among several monitor items such as
output frequency, select one to output it
via these terminals. (The signal is not
output during an inverter reset.)
The size of output signal is proportional
to the magnitude of the corresponding
monitor item.
Use terminals S1 and S2 to receive the safety stop signal
input from the safety relay module. Terminals S1 and S2 can
be used at a time (dual channel). The Inverter judges the
condition of the internal safety circuit from the status
(shorted/opened) between terminals S1 and PC, or between
S2 and PC. When the status is opened, the inverter output is
shut off.
In the initial status, terminal S1 and S2 are shorted with
terminal PC by shorting wires. Remove the shorting wires
and connect the safety relay module when using the safety
stop function.
The output status varies depending on the input status of the
safety stop signals.
The output is in HIGH state during occurrence of the internal
safety circuit fault. The output is in LOW state otherwise.
(The open collector transistor is ON (conductive) in LOW
state. The transistor is OFF (not conductive) in HIGH state.)
Refer to the FR-E800 Instruction Manual (Functional Safety)
(BCN-A23488-000) when the signal is switched to HIGH
while both terminals S1 and S2 are open. (Contact your sales
representative for this manual.)
