Torque Limit Switching 1/Torque Limit Switching 2 — Activating comb inations 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 o f the last Pattern R un from its stopping point.
44 45 Pattern Operation Trigger — Initiates the first Preset Sp eed 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 priori ty) — Overrides any serial control and r eturns the Command and Frequency
control to the settings of F003 and F004.
50 51 Hold (3-wire stop) — Decelerates th e motor to a stop.
52 53 PID Differentiation/Integration Clear — Clears the PID value.
54 55 PID Forward/Reverse Switching — Toggles the grad ient 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 durat ion 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 termin al setting.
64 65 My Function Run — Activates the conf igured My Function feature. See F977 for more information on th is
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 paramete r se tt in g s F460 and F461. Torque Control operation references
parameter settings F462 and F463.
70 71 Servo Lock — Holds the motor at 0 H z until a Run command is received.
72 73 Simple Positioning — While operating in the Positioning Control mode, activation initiates the St op command.
See F381 for more information on this terminal setting.
74 75 kWH Display Clear — Clears the kWH meter d isplay.
76 77 Trace Back Trigger— Initiates the data Read/Store fun ction 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.
