[A123]
(Auto Brake Off Delay
i,ii
) This parameter
determines the time after zero speed is
reached (level determined by the AB ZERO
SPD LEV (A1) parameter) that the Auto
Brake logic output goes false. The units are
seconds and the parameter has a maximum
value of 9.99 seconds and a default value of
0.00 seconds.

Brake Pick
Delay
iii
[A120]
(Brake Pick Delay
iii
) When external logic
outputs are used to control the mechanical
brake, this is the time delay from a drive run
command until the brake is picked. This
time delay needs to be set for the following:
have DC injection current before the
mechanical brake is picked and have DC
injection current after the mechanical brake
is picked to allow the brake to fully open.

Brake Drop
Delay
iii
[A121]
(Brake Drop Delay
iii
) When external logic
outputs are used to control the mechanical
brake and ramp to stop is selected, this
parameter sets the time delay to set the
brake after decelerating to the DC Stop
Freq. This time delay needs to be set for the
following: have DC injection current before
the mechanical brake is closed and after the
mechanical brake is picked to allow the
brake to fully open.

Brake Hold
Time
[A124]
(Brake Hold Time) If the brake hold fault is
enabled, this parameter sets the time

match the brake hold command before a
BRK HOLD FLT occurs.

DC Start
Level
iii
[A125]
(DC Injection Current Start Leveli
ii
) The
level of DC injection current at start is a
percent of motor rated current. The DC
injection current will hold the motor shaft in a
fixed position as the drive outputs a DC
current to the motor. At the start, it is
important to have DC injection current
before the mechanical brake is picked to
allow the brake to fully open

DC Stop
Level
iii
[A126]
(DC Injection Current Stop Level
iii
) The level
of DC injection current at stop is a percent of
motor rated current. To hold the motor shaft
in a fixed position the drive will output a DC
current to the motor. At the stop, it is
important to have DC injection current
before the mechanical brake is closed and to
have DC injection current after the
mechanical brake is closed to allow the
brake to fully set.
