Group 3: Brake Control - ABB DCS 500B Description

Group 3: BRAKE CONTROL

[HOLD_REF]
Input of BRAKE CONTROL-function block.
Holding torque used when the drive is running during START_DELAY or STOP_DELAY.
301 FB_I: C4
[BR_RELEASE]
Input of BRAKE CONTROL-function block.
The release command for the mechanical brake.
302 FB_I: C4
[MIN_SP_IND]
Input of BRAKE CONTROL-function block.
Indicating that speed actual is below a minimum speed limit.
303 FB_I: C4
[ACT_BRAKE]
Input of BRAKE CONTROL-function block.
Acknowledge signal from the brake. This input points to the signal, it is connected to. The
logic level on this interconnection is defined as:
0 =
<> =
If the acknowledge is not used, set [ACT_BRAKE] = 0, otherwise connect it to Digital Input
or some other function block. When brake is opened with LIFT_BRAKE (10304) output,
[ACT_BRAKE] has to indicate OPEN-status within 5 seconds, if not, the drive will trip.
304 FB_I: C4
START_DELAY
Parameter of BRAKE CONTROL-function block.
When start command is given, speed reference is released after START_DELAY has
elapsed.
305 FB_P: I2
STOP_DELAY
Parameter of BRAKE CONTROL-function block.
When stop command is given, current control is blocked when STOP_DELAY has
elapsed.
306 FB_P: I2
HOLD_TORQ
Parameter of BRAKE CONTROL-function block.
Torque reference used when the drive is running during START_DELAY or STOP_DELAY
if [HOLD_REF] is not connected.
307 FB_P: I2
EMESTOP_BRAKE
Parameter of BRAKE CONTROL-function block.
Selects the function of mechanical brake in emergency stop situation:
0 = DISABLE
1 = ENABLE
