Power section parameters \ control functions \ brake functions
Activation of brake
release without
drive enable signal
index 8893.0
This parameter is used to set the function "Brake release without drive enable":
•0 = NO
• 1 = YES
When the function is set to YES, the brake can be released even if there is no drive
enable signal.
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withdrawn (enable = "0").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.
WARNING
Risk of fatal injury if the hoist falls.
Severe or fatal injuries.
• Never use the function "Brake release without drive enable signal" for hoist
applications!
INFORMATION
For more information about releasing the brake without drive enable signal, refer to
chapter "Operation".
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".
