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.
(2) When operating in fire mode, if there is an error on auto-reset and the number of times to
auto-reset remains zero or the fire alarm rings according to the time setting for Pr.06-83, then the
bypass function is enabled. MFO bypass indication is ON. If the auto-reset is successful before
the bypass function is enabled, the bypass delay counter returns to zero to wait for next trigger.
