Configuring Mechanical brake control
Safety
WARNING!
Obey all safety instructions for the drive. Only qualified electricians are
allowed to start up the drive.
Parameter settings
Activate the brake control logic.
44.06
Brake control enable
=
Selected
Select the source for the brake acknowledgment signal.
44.07
Brake acknowledge selection
= as per the application requirements (eg. DI3 or No
acknowledge)
Define the brake open and close delay.
44.08
Brake open delay
= eg. 1 s
44.13
Brake close delay
= eg. 1 s
Notes:
• Close delay time can be longer than the mechanical delay time provided by the
mechanical brake manufacturer.
• Longer delay time can cause small roll back, and short delay time can cause wear of
the brake pads.
Select the source for the brake opening torque. At first, select the following:
44.09
Brake open torque source
=
Brake open torque
44.10
Brake open torque
= 30%
Notes:
• The break opening torque is meant for hoisting application only, and is not necessary to
use it with trolley and long travel movement applications. If used for trolley or long
travel movement applications, set the value of both parameters as 0%.
• In scalar motor control or in trolley and long travel movements, disable Torque proving
and Brake open torque. Select the following:
44.09
Brake open torque source
=
Zero
44.10
Brake open torque
= 0%
44.202
Torque proving
=
Not selected
44.203
Torque proving reference
= 0%
Set the brake close level.
44.14
Brake close level
= 30 rpm or 60 rpm
When an encoder is used, the value needs to be set as 10-30 rpm else set the value as
60 rpm.
Set break fault function to fault.
44.17
Brake fault function
=
Fault
For hoist drives, set the parameters as below:
44.202
Torque proving
=
Selected
44.203
Torque proving reference
= 30%
