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
Hand 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 Operation — 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 additional information on this terminal setting.
64 65
My Function Run — Activates the configured My Function feature. See F977 for additional 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 settings F460 and F461. Torque Control operation references 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 additional 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
additional information on this feature.
78 79 Light-Load High-Speed Disable — Terminates the Light-Load High-Speed operation.
NO/NC = Normally Open/Normally Closed.
*Selection numbers are used when configuring the ASD via communications. The Normally Open (NO) or Normally
Closed (NC) configuration must be chosen by selecting the associated number.
