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 Hoisting/Lowering Command Transition
Adjustable
0 = Off
Factory Setting:
0
Range:
1 = On
Proprieties:
Access groups via HMI: SPLC
Description:
This parameter inhibits the brake closing during the transition from hoisting to lowering and vice versa.
NOTE!
Available when a vector with encoder control mode is chosen (P0202 = 4).
P1048 – Brake Closing Frequency Threshold
Adjustable
0.5 to 500.0 Hz
Factory Setting:
2.5 Hz
Range:
Proprieties:
Access groups via HMI:
SPLC
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.
NOTE!
The delay time to close the brake does not apply in the event of a fault, coast to stop, fast stop or
emergency stop.
