124 125
Pre-excite Motor — Activation applies an excitation current to the motor (holds shaft stationary) for the duration of
the connection.
126 127
System Consistent Sequence (BC: braking command)
— Not Used.
128 129
System Consistent Sequence (B: braking release) — Activation initiates the brake release command. This
setting requires that another discrete input terminal be set to 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, 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: braking answer)
— This setting is required when the Braking Release
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.

System Consistent Sequence (BT: braking test)
— Factory use.

Output Frequency Hold
— Not Used.
Note: NO/NC = Normally Open/Normally Closed. NO/NC selection numbers are used when making system changes via
communications.
