08
SET
Set (select) 2nd Motor
Data
Switch from normal (1st) to 2nd motor parameters for gener-
ating frequency output to motor
09
2CH
2-stage Acceleration and
Deceleration
Frequency output uses 2nd-stage acceleration and decelera-
tion values
11
FRS
Free-run Stop
Causes output to turn OFF, allowing motor to free run (coast)
to stop
12
EXT
External Trip
At OFF to ON transition, inverter latches trip event and
displays E12 (until a reset occurs)
13
USP
Unattended Start Protec-
tion
On powerup, the inverter will not resume a Run command
that was active before power loss (mostly used in the US)
14
CS
Commercial Power
Source
OFF-to-ON transition signals the inverter that the motor is
already running at powerup (via bypass), thus suppressing the
inverter’s motor output in Run Mode; ON-to-OFF transition
signals the inverter to apply a time delay (B003), frequency
match its output to existing motor speed, and resume normal
Run Mode operation
15
SFT
Software Lock
The keypad and remote programming devices are prevented
from changing parameters
16
AT
Analog Input Voltage/
current Select
ON condition: If A005=00, terminal [OI] is enabled for
input. If A005=01, terminal [O2] is enabled for input. (Use
terminal [L] for signal return.)
OFF condition: Terminal [O] is enabled for voltage input (use
terminal [L] for signal return).
17
SET3
Set (select) 3rd motor data Switch from normal (1st) to 3rd motor parameters for gener-
ating frequency output to motor
18
RS
Reset Inverter
Resets the trip condition, turns OFF the motor output, and
asserts powerup reset
20
STA
START
(3-wire interface)
Starts the motor rotation
21
STP
STOP
(3-wire interface)
Stops the motor rotation
22
F/R
FWD, REV
(3-wire interface)
Selects the direction of motor rotation: ON =FWD;
OFF =REV. While the motor is rotating, a change of F/R will
start a deceleration, followed by a change in direction.
23
PID
PID Disable
Temporarily disables PID loop control. Inverter output turns
OFF as long as PID Enable is active (A071=1).
24
PIDC
PID Reset
Resets the PID loop controller. The main consequence is that
the integrator sum is forced to zero.
26
CAS
Control gain setting
To select the source of internal speed loop gain...
OFF selects parameters H050 to H052 (or H250 to H252 for
2nd motor); ON selects alternate parameters H070 to H072
27
UP
Remote Control
UP Function (motorized
speed pot.)
Accelerates (increases output frequency) motor from current
frequency
28
DWN
Remote Control DOWN
Function (motorized
speed pot.)
Decelerates (decreases output frequency) motor from current
frequency
