Brake function
index 8584.0
This function gives users the option to choose between electrically holding the load and
mechanical brake application in hold status.
The parameter defines whether the brake is applied or not when the enable signal is
withdrawn (enable = "0").
• 0 = OFF: The drive decelerates along the set ramp. When the speed is "0", the brake
remains open and the drive generates a holding torque.
• 1 = ON: The drive decelerates along the set ramp. When the speed is "0", the brake
is applied.
Brake application
for STO
index 9833.20
The parameter defines whether the brake is applied or not (not safety-related) when
STO (safe torque off) is triggered.
• 0 = NO: The brake status remains unchanged when STO is triggered.
• 1 = YES: The brake is applied when STO is triggered.
INFORMATION
• The brake is
always
applied when /CONTROL.INHIBIT = 0.
• When "STO – safe torque off" is activated, the brake is applied (not safety-related)
as set in parameter "Index 9833.20 – brake application for STO".
INFORMATION
Note the information about permitted "emergency braking operations" in chapter
"Technical Data".
