Parameters 357
43.11 Brake resistor fault
limit Selects the fault limit for the brake resistor protection based
on the thermal model. See parameter
43.06 Brake chopper
function . When the limit is exceeded, the drive trips on fault
7183 BR excess temperature .
The value is given in percent of the temperature the resistor
reaches when loaded with the power defined by parameter
43.09 Brake resistor Pmax cont .
105%
0 … 150% Brake resistor temperature fault limit. 1 = 1%
43.12 Brake resistor
warning limit Selects the warning limit for the brake resistor protection
based on the thermal model. See parameter
43.06 Brake
chopper function . When the limit is exceeded, the drive
generates a A793 BR excess temperature warning.
The value is given in percent of the temperature the resistor
reaches when loaded with the power defined by parameter
43.09 Brake resistor Pmax cont .
95%
0 … 150% Brake resistor temperature warning limit. 1 = 1%

Mechanical brake control (page 107 ).
44.01 Brake control status Displays the mechanical brake control status word.
This parameter is read-only. -
0000h…FFFFh Mechanical brake control status word. 1 = 1
44.02 Brake torque
memory Displays the torque (in percent) at the instant of the previous
brake close command.
This value can be used as a reference for the brake open
torque. See parameters
44.09 Brake open torque source and
44.10 Brake open torque .
-
-1600.0 … 1600.0% Torque at brake closure. See par.
46.03
44.03 Brake open torque
reference Displays the currently active brake open torque. See
parameters
44.09 Brake open torque source and 44.10 Brake
open torque .
This parameter is read-only.
-
-1600.0 … 1600.0% Currently active brake open torque. See par.

Bit Name Information
0 Open command Close/open command to brake actuator (0 = close, 1 = open).
Connect this bit to desired output.
1 Opening torque
request 1 = Opening torque requested from drive logic
2 Hold stopped
request 1 = Hold requested from drive logic
3 Ramp to stopped 1 = Ramping down to zero speed requested from drive logic
4 Enabled 1 = Brake control is enabled
5 Closed 1 = Brake control logic in BRAKE CLOSED state
6 Opening 1 = Brake control logic in BRAKE OPENING state
7 Open 1 = Brake control logic in BRAKE OPEN state
