32 33
Torque Limit Switching 1/Torque Limit Switching 2
— Activating combinations of discrete input terminals
Torque Limit Switching 1 and 2 allow for the selection of a torque limit switching profile as listed below.
34 35
36 37
PID Off
— Turns off PID control.
38 39 Pattern Operation Group 1 — Initiates the Pattern #1 Pattern Run.
40 41
Pattern Operation Group 2
— Initiates the Pattern #2 Pattern Run.
42 43
Pattern Operation Continuation
— Initiates a continuation of the last Pattern Run from its stopping point.
44 45
Pattern Operation Trigger
— Initiates the first Preset Speed of a Pattern Run and initiates each subsequent
enabled Preset Speed with continued activations.
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 the settings of 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 Continuous Run
— Ignore PID control settings for the duration of activation.
58 59 Specified Speed Operation — Runs speed as commanded by the Frequency Mode setting.
60 61
Dwell Signal
— Used in conjunction with the Acceleration/Deceleration Suspend function ( F349 ) — suspends the
Accel/Decel function for the duration of the activation.
62 63
Power Failure Synchronized Signal — Activates the Synchronized Accel/Decel function of the Regenerative
Power Ridethrough feature. See F302 for more information on this terminal setting.
64 65
My Function Run — Activates the configured My Function feature. See F977 for more information on this
parameter.
66 67
Autotuning Signal
— Initiates the Autotune function. Set F400 to Autotuning by Input Terminal Signal.
68 69
Speed Gain Switching
— Toggles the ASD operating mode from and to Speed Control and Torque Control.
Speed Control operation references parameter settings F460 and F461 . Torque Control operation references
parameter settings F462 and F463 .
70 71 Servo Lock — Holds the motor at 0 Hz until a Run command is received.
72 73
Simple Positioning
— While operating in the Positioning Control mode, activation initiates the Stop command.
See F381 for more information on this terminal setting.
74 75 kWH Display Clear — Clears the kWH meter display.
76 77
Trace Back Trigger
— Initiates the data Read/Store function of the Trace Selection parameter. See F740 for more
information on this feature.
78 79 Light-Load High-Speed Disable — Terminates the Light-load High-speed operation.
Note: NO/NC = Normally Open/Normally Closed.
