• Sequence Circuit Configuration and Timing Chart Examples
For the AC sequence circuit,
connect the signal between P1 and
PC to the sequence circuit with a
relay.
Design the sequence so that the
hoiding brake contact is open
when the sequense operation
conditions are satisfied and the
contact between P1 and PC is
closed(ON).
Make sure that the holding brake
contact is closed when the
emergency stop signal or inverter
fault contact output signal is ON.
• For V/f Control and Vector Control
• For a variable speed operation by an analog signal, set the frequency reference selection
(n004) to a value from 2 to 4.
