Sel. No.
NO NC
Note: NO/NC = Normally Open/Normally Closed. NO/NC selection numbers are used when making system changes via
communications
Binary Write — Writes the status of the discrete input terminals to the control board during binary input speed
86 87
control.
UP/DOWN Frequency (up) — Increases the speed of the motor for the duration of activation until reaching the
88 89
Upper-Limit setting or increases the speed of the motor in steps (
UP/DOWN Frequency (down) — Decreases the speed of the motor for the duration of activation until reaching the
90 91
Lower-Limit setting or decreases the speed of the motor in steps (
UP/DOWN Frequency (clear) — While operating in the Up/Down Frequency speed control mode this terminal
92 93 initiates a 0 Hz output command. If operating with an activated UP/DOWN Frequency (up or down) terminal, the
output goes to the Lower-Limit (F013) setting.
Forward/Reverse — Operates in conjunction with another terminal being set to the Run/Stop (100/101) function.
98 99 When configured to Run (Run/Stop to CC), the activation/deactivation of this terminal changes the direction of the
motor.
100 101 Run/Stop — This terminal enables the motor to run when activated and disables the motor when deactivated.
Commercial Power/ASD Switching — Initiates the ASD-to-Commercial Power switching function.
102 103
See parameter F354
Frequency Reference Priority Switching — Toggles frequency control to and from the settings of
104 105
F207.
106 107 V/I Terminal Priority — Assigns Speed control to the V/I Terminal and overrides the
Command Terminal Board Priority — Assigns Command control to the Terminal Board and overrides the
108 109
setting.
110 111 Edit Enable — Allows for the override of the lock out parameter setting (F700) allowing for parameter editing.
112 113 Control Switching — Toggles the system to and from the speed control and the torque control modes.
Fast Deceleration — Using dynamic braking (if enabled and supported), stops the motor at the fastest rate allowed
122 123
by the load.
Preliminary Excitation — Applies an excitation current to the motor (holds shaft stationary) for the duration of the
124 125
activation.
Brake Request — Initiates the brake release command. This setting requires that another discrete input terminal be
set to Brake Answerback Input to complete the brake release command and to convey the status of the braking
system to the user or to a dependent subsystem.
Once the braking release function is initiated, the Trouble Internal Timer begins to count down (Trouble Internal
126 127 Timer value is set at F630). Should the count-down timer expire before the brake releases or before the Brake
Answerback Input is returned, fault E-11 will occur. Otherwise, the brake releases the motor and normal motor
operations resume.
The Braking Release function is primarily used at startup; but, may be used when the brake is applied while the motor
is running.
Brake Answerback Input — This setting is required when the Braking Request function is used. The function of
this input terminal is to receive the returned the status of the braking system. The returned status is either Released or
Not Released.
130 131
If Released is returned within the time setting of F630, normal system function resumes.
If Not Released is returned or if the
The returned signal may also be used to notify the user or control a dependent subsystem.
134 135 Traverse Permission Signal — Enables/Disables the Traverse function.
136 137 Start-Stop HOA — Activates the Auto Start-Stop operating mode in accordance with the settings of F385.
Low Suction/No Flow Protection — Will not allow the ASD to start if activated, or terminates the ASD output
138 139
upon activation (if running) in the event of the loss of feed water or a closed output valve at the pump output.
