The brake sequence control operates with the ”open holding brake”
output signal. The signal can be output as follows:
Motor with integrated holding brake (only 300 W motors)
No additional wiring is required for the brake sequence control.
Motor with external holding brake
The external holding brake is controlled using a digital output with
function number 95 (open holding brake).
The following must be observed:
– Output terminal X5, I/Q1, I/Q2
– Activated via P56.4 and P56.6
– Parameterizing the output terminal ––> refer to Chapter 5.5.10
– Connecting up the output terminal ––> refer to Chapter 2.3
– The relay for the holding brake is connected at the parameterized
output terminal.
The following parameters are available for the ”Holding brake” function:
P31 function, terminal 1
P32 function, terminal 2
P56.4 open holding brake
P56.5 monitoring, holding brake undervoltage
P56.6 open the holding brake, also for an external holding
brake
P58 holding brake, brake opening time
P59 speed, close holding brake
P60 holding brake, brake delay time
P61 holding brake, controller inhibit time
