1. If the inverter is set as external terminal control mode (1-00=1) and
direct start is disabled (2-04=0001), the inverter cannot be started
and will flash STP1 when operation switch turned to ON after
applying power (refer to descriptions of 2-04).
2. Direct start is possible when 2-04=0001.
1. If the inverter is set as external control mode (1-00=0001) and Stop
key is enabled (1-03=0000), the inverter will stop according to the
setting of 1-05 when Stop key is pressed. STP2 flashes after stop.
Turn the operation switch to OFF and then ON again to restart the
inverter.
2. If the inverter is in communication mode and Stop key is enabled (1-
03=0000), the inverter will stop in the way set by 1-05 when Stop
key is pressed during operation and then flashes STP2. The PC has
to send a Stop command then a Run command to the inverter for it to
be restarted.
3. Stop key cannot perform emergency stop when 1-03=0001
The inverter will ramp stop and then flash E.S., when input external
emergency stop signal via the multifunctional input terminal (refer to
descriptions of 5-00~5-06).
The inverter stops immediately and then flashes b.b., when external
base block is input through the multifunctional input terminal (refer
to descriptions of 5-00~5-06).
1. Motor data error resulting in for auto-tuning failure
2. Stop the inverter emergently during Auto-tuning
