H9 ASD Installation and Operation Manual
86
87
Binary Write
— Writes the status of the discrete input terminals to the control board during binary input speed
control.
88
89
UP/DOWN Frequency
(up) — Increases the speed of the motor for the duration of activation until reaching the
Upper-Limit
setting or increases the speed of the motor in steps (see
F264
for more information on this feature).
90
91
UP/DOWN Frequency
(down) — Decreases the speed of the motor for the duration of activation until reaching the
Lower-Limit
setting or decreases the speed of the motor in steps (see
F264
for more information on this feature).
92
93
UP/DOWN Frequency
(clear) — While operating in the
Up/Down Frequency
speed control mode this terminal
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.
98
99
Forward/Reverse
— This setting operates in conjunction with another terminal being set to the
Run/Stop
function.
When configured to
Run
(
Run/Stop
to
CC
), the make or break of this connection to
CC
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.
102 103
Commercial Power/ASD Switching
— Initiates the
ASD-to-Commercial Power
switching function.
See parameter
F354
for more information on this feature.
104 105
Frequency Reference Priority Switching
— Toggles frequency control to and from the settings of
F004
and
F207
.
106 107
V/I Terminal Priority
— Assigns
Speed
control to the
V/I Terminal
and overrides the
F004
setting.
108 109
Command Terminal Board Priority
— Assigns
Command
control to the
Terminal Board
and overrides the
F003
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.
122 123
Fast Deceleration
— Using dynamic braking (if enabled and supported), stops the motor at the fastest rate allowed
by the load.
124 125
Preliminary Excitation
— Applies an excitation current to the motor (holds shaft stationary) for the duration of the
activation.
126 127
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
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.
130 131
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
.
If
Released
is returned within the time setting of
F630
, normal system function resumes.
If
Not Released
is returned or if the
F630
time setting times out before either signal is returned, then fault
E-11
occurs.
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. See parameter
F980
for more information
on this feature.
Note:
NO/NC = Normally Open/Normally Closed.
