Below diagram shows the sequence of fire mode operation. The operation mode will accord to the
Pr.06-86 bit0 setting (bit0: 0=Open Loop; 1=Close Loop (PID control)).
The Fire mode operating procedure:
Pr.06-86 bit0=0: When setting Pr.06-80=1 or 2, and the multi-functional input terminals MIx=58 is ON,
the drive enables the fire mode operation. The drive accelerates to the setting frequency for Pr.06-81,
and the keypad KPC-CC01 displays a “Fire” warning. The drive outputs a RUN command for the fire
mode when the multi-function output terminal MOx is set to 53. If you set Pr.06-82=1 to enable the
Bypass function and the condition is established, the MOx=54 Bypass fire mode indicates action and
switches the motor power to the mains power, then the drive stops.
Pr.06-86 bit0=1: When setting the Pr.06-80=1 or 2, and the multi-functional input terminals MIx=58 is
ON, the drive enables the fire mode operation. The drive runs PID control with Pr.06-87 as PID set
point, and the keypad KPC-CC01 displays a “Fire” warning. The drive outputs a RUN command for
the fire mode when the multi-function output terminal MOx is set to 53. If you set Pr.06-82=1 to
enable the Bypass function and the condition is established, the MOx=54 Bypass fire mode indicates
action and switches the motor power to the mains power, then the drive stops.
If an error occurs to the PID feedback signal, the drive switches to the open-loop control and runs
according to the setting frequency for Pr.06-81.
Bypass function operating sequence:
Conditions are required to enable the Bypass function. When Pr.06-82 is set to 1, there is one of two
conditions:
(1) When operating in fire mode, there is an error (as shown in the table below) and the fire alarm
rings according to the time setting for Pr.06-83, and then the bypass function is enabled. MFO
bypass indication is ON.
