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
for additional 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
for additional 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
) setting.
98
99
Forward/Reverse
— Operates in conjunction with another terminal being set to the
Run/Stop
(100/101) function.
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.
102 103
Commercial Power/ASD Switching
— Initiates the
ASD-to-Commercial Power
switching function.
See
for additional information on this feature.
104 105
Frequency Reference Priority Switching
— Toggles frequency control to and from the settings of
and
106 107
V/I Terminal Priority
— Assigns
Speed
control to the
V/I Terminal
and overrides the
setting.
108 109
Command Terminal Board Priority
— Assigns
Command
control to the
Terminal Board
and overrides the
setting.
110 111
Edit Enable
— Allows for the override of the lock out setting (
), 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
). 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 status of the braking system. The returned status is either
Released
or
Not
Released
.
If
Released
is returned within the time setting of
, normal system function resumes.
If
Not Released
is returned or if the
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.
136 137
Start-Stop HOA
—
Activates the
Auto Start-Stop
operating mode in accordance with the settings of
.
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.
