1 With electronic bypass sequence
Set the operation interlock time of MC2 and
0.1s 1s 0 to 100s
MC3.
Set the time slightly longer (0.3 to 0.5s or
0.1s 0.5s 0 to 100s so) than the time from when the ON signal
enters MC3 until it actually turns on.
Inverter output is stopped (motor coast) at
0
inverter fault.
Operation is automatically switched to
1 0
bypass operation at inverter fault (Not
1 switched when an external thermal relay
operation (E.OHT) or CPU fault (E.CPU)
occurs)
Set the frequency to switch inverter
0 to 60Hz
operation to bypass operation.
0.01Hz 9999
9999 Without automatic switchover
Valid during automatic switchover operation
(Pr.139 ≠ 9999)
When the frequency command decreases
below (Pr.139 - Pr.159) after operation is
switched from inverter operation to bypass
operation, the inverter automatically
0 to 10Hz
switches operation to inverter operation
and operates at the frequency of frequency
command.
When the inverter start command (STF/
0.01Hz 9999
STR) is turned off, operation is switched to
inverter operation also.
Valid during automatic switchover operation
(Pr.139 ≠ 9999)
When the inverter start command (STF/
STR) is turned off after operation is
9999
switched from inverter operation to bypass
operation, operation is switched to inverter
operation and the motor decelerates to
stop.
