Parameters Description
Crane | 56
Description:
This parameter define the motor current threshold to release the brake. In other words, if the actual motor
current is higher than or equal to the adjusted value, then the brake release command is permitted. It is also
necessary that the other conditions be satisfied for effectively commanding the brake release.
NOTE!
Setting this parameter in 0.0 disables the motor current verification for the brake control.
P1045 – Brake Release Torque Threshold
Adjustable
0.0 to 350.0 %
Factory Setting: 0.0 %
Range:
Proprieties:
Access groups via HMI:
SPLC
Description:
This parameter define the motor torque threshold to release the brake. In other words, if the actual motor torque
is higher than or equal to the adjusted value, then the brake release command is permitted. It is also necessary
that the other conditions be satisfied for effectively commanding the brake release.
NOTE!
Setting this parameter in 0.0 disables the motor torque verification for the brake control.
P1046 – Brake Response Time to Release
Adjustable
0.00 to 650.00 s
Factory Setting: 0.10 s
Range:
Proprieties:
Access groups via HMI:
SPLC
Description:
This parameter defines the brake response time to release, or how long the brake takes to release after
receiving the command from the digital output of the CFW500, and thus be mechanically released.
NOTE!
In time for the brake release, the speed reference is kept in the brake release frequency threshold if it
is enabled (P1041 ≠ 0). This avoids the increase of the motor frequency with the brake closing can
thus minimize motor current spikes.
P1047 – Inhibition of the Brake Closing during a Forward/Reverse Command Transition
Adjustable
0 = Disabled
Factory Setting: 0
Range:
1 = Enabled
Proprieties:
Access groups via HMI:
SPLC
Description:
This parameter inhibits the brake closing during the transition from load forward to load reverse and vice versa.
P1048 – Brake Closing Frequency Threshold
Adjustable
0.5 to 500.0 Hz
Factory Setting: 2.5 Hz
Range:
Proprieties:
Access groups via HMI:
SPLC
