• Sequence Circuit Configuration and Timing Chart Examples
For the AC sequence cir-
cuit, connect the signal
between P1 and PC to the
sequence circuit with a
relay.
Design the sequence so
that the holding brake con-
tact is open when the
sequence operation condi-
tions 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.
