Wegner Crane CFW500 series Applications Manual - page 57
Parameters Description
Crane | 57
Description:
This parameter defines the motor frequency threshold to close the brake. In other words, if the total speed
reference after the ramp is less than or equal to that threshold, a command for brake closing is issued.
P1049 – Delay Time for Brake Closing
Adjustable
0.00 to 650.00 s
Factory Setting: 0.00 s
Range:
Proprieties:
Access groups via HMI:
SPLC
Description:
This parameter defines a delay after the frequency threshold condition to close the brake is fulfilled, before
effectively issuing the brake closing command.
P1050 – Time to Enable a new Command to Brake Release
Adjustable
0.10 to 650.00 s
Factory Setting: 0.20 s
Range:
Proprieties:
Access groups via HMI:
SPLC
Description:
This parameter defines a time after the command to brake closing has been executed via the digital output of
the CFW500, so that a new command to load forward or load reverse is accepted and thus the brake can be
released again thus preventing a new command to be generated without the brake being closed mechanically.
NOTE!
The value of the set time should be sufficient to ensure that a new command to load forward or load
reverse performs with the brake closed, but that does not generate a very large delay in the crane
horizontal motion operation.
NOTE!
Refer to the section 2.4 in this application manual for more information on the connection diagram
and brake power supply.
