Position Control Reverse Limit LS — Connecting this terminal to CC will immediately stop the drive and hold its position. If
the connection remains, the drive will time-out and trip. This function is normally used for over-travel conditions.
120
121
Light-Load High-Speed Operation Enable — Sets the lower limit of an output frequency range in which the Light-Load
High-Speed function may be used (see F330). The Light-Load High-Speed function accelerates the output frequency of the
ASD to the speed setting established in
122
123
Lag Down Control Valid — Not used.
124
125
Spare Excitation — Not used.
126
127
System Consistent Sequence (BC: Brake Command) — Not used.
128
129
System Consistent Sequence (B: Brake Release) — Connecting this input terminal to CC initiates the brake release command.
This setting requires that another discrete input terminal be set to 65 [System Consistent Sequence (BA: braking answer)] 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 Braking Answer is returned, a
Brake 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
System Consistent Sequence (BA: Brake Answer) — Required when the Braking Release (64) 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 F630, normal system function resumes.
If Not Released is returned or if the
occurs.
The returned signal may also be used to notify the user or control a dependent subsystem.
132
133
System Consistent Sequence (BT: Brake Test) — Factory use.
134
135
Output Frequency Holding Command — Retains the running frequency at power down. Upon a restart, the retained
frequency at the power down is the restart frequency.
136
137
Test — For factory use.
Note: NO/NC = Normally Open/Normally Closed.
Note: Selection numbers are used when configuring the discrete input terminals via communications. They differentiate the Normally
Open and Normally Closed contact settings.
