Input Function Summary Table
Option
Code
Terminal
Symbol Function Name Description
ON Frequency output uses 2nd-stage acceleration and
deceleration values
09 2CH 2-stage Acceleration
and Deceleration OFF Frequency output uses standard acceleration and
deceleration values
ON Causes output to turn OFF, allowing motor to free run
(coast) to stop
11 FRS Free-run Stop
OFF Output operates normally, so controlled deceleration
stop motor
ON When assigned input transitions OFF to ON, inverter
latches trip event and displays E 12
12 EXT External Trip
OFF No trip event for ON to OFF, any recorded trip events
remain in history until reset
ON On powerup, the inverter will not resume a Run
command (mostly used in the US)
13 USP Unattended Start
Protection OFF On powerup, the inverter will resume a Run command
that was active before power loss
ON Motor can be driven by commercial power
14 CS Commercial power
source switchover OFF Motor is driven via the inverter
ON The keypad and remote programming devices are
prevented from changing parameters
15 SFT Software Lock
OFF The parameters may be edited and stored
ON
16 AT Analog Input
Voltage/Current Select OFF Refer to “Analog Input Operation” on page 41.
ON The trip condition is reset, the motor output is turned
OFF, and powerup reset is asserted
18 RS Reset Inverter
OFF Normal power-ON operation
ANLG
When a thermistor is connected to terminal [5] and [L],
the inverter checks for over-temperature and will cause
trip event and turn OFF output to motor
19 PTC
PTC thermistor
Thermal Protection
(C005 only)
OPEN
A disconnect of the thermistor causes a trip event, and
the inverter turns OFF the motor
ON Starts the motor rotation
20 STA Start
(3-wire interface) OFF
No change to present motor status
ON Stops the motor rotation
21 STP Stop
(3-wire interface) OFF No change to present motor status
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
22 F/R FWD, REV
(3-wire interface)
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
ON Temporarily disables PID loop control. Inverter output
turns OFF as long as PID Enable is active (A071=01)
23 PID PID Disable
OFF Has no effect on PID loop operation, which operates
normally if PID Enable is active (A071=01)
ON Resets the PID loop controller. The main consequence
is that the integrator sum is forced to zero
24 PIDC PID Reset
OFF No effect on PID controller
ON Accelerates (increases output frequency) motor from
current frequency
27 UP Remote Control UP
Function (motorized
speed pot.) OFF Output to motor operates normally
ON Decelerates (decreases output frequency) motor from
current frequency
28 DWN Remote Control Do wn
Function (motorized
speed pot.) OFF Output to motor operates normally
