Terminal Selection Descriptions
NO NC
01Unassigned — No operation.
23Forward — Provides a Forward run command.
45Reverse — Provides a Reverse run command.
67Standby — Enables the Forward and Reverse operation commands.
89Reset — Resets the device and any active faults.
10 11 (Pre)Set Speed 1 —Preset Speed 1 is used as the LSB of the 4-bit nibble that is used to select a Preset Speed.
12 13 (Pre)Set Speed 2 — Preset Speed 2 is used as the second bit of the 4-bit nibble that is used to select a Preset Speed.
14 15 (Pre)Set Speed 3 — Preset Speed 3 is used as the third bit of the 4-bit nibble that is used to select a Preset Speed.
16 17 (Pre)Set Speed 4 — Preset Speed 4 is used as the MSB of the 4-bit nibble that is used to select a Preset Speed.
18 19
Jog — Jog is the term used to describe turning on the motor for discrete increments of time and is used when precise
positioning of motor-driven equipment is required. This terminal activates a Jog for the duration of the activation. The
Jog settings may be configured at F260 – F262.
20 21
Emergency Off — Terminates the output signal from the drive and may apply a brake if so configured. The braking
method may be selected at F603.
22 23
DC Braking — The drive outputs a DC current that is injected into the windings of the motor to quickly brake the
motor.
24 25
A/D 1/2 — Accel/Decel Switching 1 and 2 — Activate or deactivate this terminal to toggle to and from the Accel/
Decel profile 1 and 2.
Accel/Decel profiles are comprised of the Accel/Decel settings, Pattern, and
Switching Frequency, respectively.
See F504 for more information on this terminal setting.
28 29
Motor 1/2 — Motor Profile 1 and 2 — Activate or deactivate this terminal to select Motor profile 1 or 2, respectively.
Motor profiles are comprised of Frequency Mode 1 and 2, Base Frequency/Base Frequency Voltage, Torque
Boost, and Electronic Thermal Protection Level settings.
36 37 PID Off — Turns off PID control.
46 47 External Over-heat — Causes an Over-Heat Trip (OH).
48 49
Local Priority (Cancels Serial Priority) — Overrides any serial control and returns the Command and Frequency
control to F003 and F004.
50 51 Hold (3-Wire Stop) — Decelerates the motor to a stop.
52 53 PID Differentiation/Integration Clear — Clears the PID value.
54 55
PID Forward/Reverse Switching — Toggles the gradient characteristic of the feedback response of the V/I
terminal during PID-controlled operation.
56 57 Forced Run — PID control is ignored for the duration of activation.
58 59 Fire Speed — Run Preset Speed 15 for the duration of the activation (see F294 for more information on this setting).
60 61
My Function Run — Activates the configured My Function feature. See F977 for more information on this
parameter.
66 67
Autotuning — Initiates the Autotune function. Set F400 to Autotuning by Input Terminal Signal to use this
function.
70 71
Servo Lock — Holds the motor at 0 Hz until a Run command is received.
74 75 kWH Clear — Clears the kWH Meter display.
76 77
Trace Back — Initiates the data Read/Store function of the Trace Selection parameter. See F740 for more
information on this feature.
80 81
Damper Feedback — Activation of this terminal indicates an open damper and enables the system for normal
operation. This terminal connects to a Damper Open/Damper Closed switch.
86 87
Binary Write — Writes the status of the discrete input terminals to the control board during binary input speed
control.
Note: NO/NC = Normally Open/Normally Closed.
