06
JG Jogging
ON
Inverter is in Run Mode, output to motor runs at jog
parameter frequency
OFF Inverter is in Stop Mode
07
DB External DC braking
ON DC braking will be applied during deceleration
OFF DC braking will not be applied
08
SET
Set (select) 2nd
Motor Data
ON
The inverter uses 2nd motor parameters for
generating frequency output to motor
OFF
The inverter uses 1st (main) motor parameters for
generating frequency output to motor
09
2CH
2-stage Acceleration
and Deceleration
ON
Frequency output uses 2nd-stage acceleration and
deceleration values
OFF
Frequency output uses standard acceleration and
deceleration values
11
FRS Free-run Stop
ON
Causes output to turn OFF, allowing motor to free
run (coast) to stop
OFF
Output operates normally, so controlled deceleration
stop motor
12
EXT External Trip
ON
When assigned input transitions OFF to ON, inverter
latches trip event and displays
OFF
No trip event for ON to OFF, any recorded trip
events remain in history until reset
13
USP
Unattended Start
Protection
ON
On power up, the inverter will not resume a Run
command (mostly used in the US)
OFF
On power up, the inverter will resume a Run
command that was active before power loss
15
SFT Software Lock
ON
The keypad and remote programming devices are
prevented from changing parameters
OFF The parameters may be edited and stored
18
RS Reset Inverter
ON
The trip condition is reset, the motor output is turned
OFF, and power up reset is asserted
OFF Normal power-ON operation
20
STA
Start
(3-wire interface)
ON Starts the motor rotation
OFF No change to present motor status
21
STP
Stop
(3-wire interface)
ON Stops the motor rotation
OFF No change to present motor status
22
F/R
FWD, REV
(3-wire interface)
ON
Selects the direction of motor rotation: ON = FWD.
While the motor is rotating, a change of F/R will start
a deceleration, followed by a change in direction
OFF
Selects the direction of motor rotation: OFF = REV.
While the motor is rotating, a change of F/R will start
a deceleration, followed by a change in direction
