[BRAKE LOGIC CONTROL] (bLC-)
Code Name/Description Setting range Factory settings
bLC- [BRAKE LOGIC CONTROL]
Note:
This function cannot be used with certain other functions. Follow the instructions in see "APPLICATION FUNCT. FUn-" on page 197 .
bLC
[BRAKE LOGIC CONTROL] [No]
(nO)
Note:
If the brake is assigned, only a ramp stop is possible.
Check the parameter
[STOP MODE] (Stt) ( see "STOP MODE (Stt-)" on page 206 ).
The brake logic control can only be assigned if [Motor control type] (Ctt) = [SVC U] (UUC) , [SVC I] (CUC) or [FVC] (FUC) , or if [Motor control
type] (Ctt) = [V/f Reg 2P] (UF2) .
Logic output or control relay
nO [No] (nO) : Function not assigned (in this case, none of the functions can be accessed).
r2 [CONFIGURATION R2] (r2)
dO1
[DO1]
(dO1) : Analog output AO, which can be used as logic output. The parameter is accessible when
[CONFIGURATION AO1]
(AO1) =
[No]
(nO) .
bSt [Movement type] [Hoist] (UEr)
HOr [Horizontal] (HOr) : Resistive-load movement (translational motion of overhead crane, for example).
Note:
If [Motor control type] (Ctt) = [V/f Reg 2P] (UF2) , [Type of movement] (bSt) is forced to [Translation] (HOr) .
UEr [Hoist] (UEr) : Driving-load movement (hoisting winch, for example).
If [ext. sensor] (PES) does not equal [No] (nO) , [Type of movement] (bSt) is forced to [Hoist] (UEr) .
bCI [Brake contact] [No] (nO)
If the brake has a monitoring contact (closed for released brake).
nO [No] (nO) : Function not active.
LI1 [LI1] (LI1)
- .

[...] (...) : See the assignment conditions
bIP [Brake impulse] [No] (nO)
The parameter is accessible if [ext. sensor] (PES) = [No] (nO) and if [type of movement] (bSt) = [Hoist] (UEr) .
nO [No] (nO) : The motor torque is specified in the required direction with current (Ibr) .
YES [Yes] (YES) : The Motor torque is always in the forward direction (make sure that this direction corresponds to the lifting operation), in the case
of braking current (Ibr) .
2Ibr [2 IBR poss.] (2Ibr) : The motor torque has the required direction of rotation, with current (Ibr) for forward run and (Ird) for reverse run; for certain
specific applications.
Ibr [Brake locked rotor current]
1)
0 to 1.32 In
2)
0
Brake release current threshold for ascending or forward movement.
The parameter is accessible when [ext. sensor] (PES) = [No] (nO) .
Ird [Brake release I Rev]
1)
0 to 1.32 In
2)
0
Brake release current threshold for descending or reverse movement.
The parameter is accessible when [brake impulse] (bIP) = [2 IBR poss.] (2Ibr) .
brt
[Brake Release time]
1)
0 to 5 s 0
Brake release time delay.
bIr [Brake release freq.]
1)
[Auto] (AUtO)
Brake release frequency threshold (initialization of acceleration ramp).
The parameter is accessible if [Motor control type] (Ctt) does not equal [FVC] (FUC) and if [Bewegungsart] (bSt) is the same as [Hoist] (UEr) .
AUtO [Auto] (AUtO) : The inverter takes a value equal to the rated slip of the motor, calculated using the inverter parameters.
- 0 to 10 Hz : Manual adjustment
bEn [Brake engage freq.]
1)
[Auto] (AUtO)
Threshold of the braking torque frequency.
The parameter is not accessible if [Motor control type] (Ctt) is not [FVC] (FUC) .
AUtO [Auto] (AUtO) : The inverter takes a value equal to the rated slip of the motor, calculated using the inverter parameters.
- 0 to 10 Hz: Manual adjustment
bECd [Brake sl. at 0] [No] (nO)
Brake is engaged at a controlled speed zero.
The parameter is not accessible if [Motor control type] (Ctt) = [FVC] (FUC) .
Can be used to engage the brake in the closed control loop with speed control at zero speed.
This parameter can be used to adjust the brake delay after reaching the zero speed.
If a different speed than zero is required, after the application of the torque the command for releasing the brake is sent.
nO
[No]
(nO) : Brake is not engaged at a controlled speed zero.
- 0.0 to 30.0 s : Brake engaging delay after reaching the zero speed.
tbE
[Brake engage delay]
1)
0 to 5 s 0
Time delay before request to engage brake. To delay the engaging of the brake if the brake is applied as soon as the inverter is completely stopped.
bEt
[Brake engage time]
1)
0 to 5 s 0
Brake engage time (brake response time)
SdC1 [Auto DC inj. level 1]
