Special operation and frequency control — Switching between the inverter and the bypass
operation (Pr.135 to Pr.139, Pr.159)

0 Without electronic bypass sequence
1 With electronic bypass sequence
136
MC switchover
interlock time
0.1s 1s 0 to 100s
Set the operation interlock time of MC2 and
MC3.
137
Start waiting time
0.1s 0.5s 0 to 100s
Set the time slightly longer (0.3 to 0.5s or so)
than the time from when the ON signal enters
MC3 until it actually turns ON.
138
Bypass selection at a
fault
10
0
Inverter output is stopped (motor coast) at
inverter fault.
1
Operation is automatically switched to bypass
operation at inverter fault (Not switched when
an external thermal relay operation (E.OHT) or
CPU fault (E.CPU) occurs)
139
Automatic switchover
frequency from
inverter to bypass
operation
0.01Hz 9999
0 to 60Hz
Set the frequency to switch inverter operation
to bypass operation.
9999 Without automatic switchover
159
Automatic switchover
frequency range from
bypass to inverter
operation
0.01Hz 9999
0 to 10Hz
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 switches
operation to inverter operation and operates at
the frequency of frequency command.
When the inverter start command (STF/STR) is
turned OFF, operation is switched to inverter
operation also.
9999
Valid during automatic switchover operation
(Pr.139 ≠ 9999)
When the inverter start command (STF/STR) is
turned OFF after operation is switched from
inverter operation to bypass operation,
operation is switched to inverter operation and
the motor decelerates to stop.
