Code Name/Description Setting range Factory settings
brH2 [BRH b2] 0
Taking the brake feedback into account for the brake control sequence.
0 [0] (0) : The brake contact remains unconsidered.
1 [1] (1) : The brake contact is considered.
Use in the open and closed-loop control
• If a logic input is assigned to the brake contact.
[BRH b2] (brH2) = 0: During the brake release sequence, the reference is unlocked after the end of the [brake engage time] (brt) . During
the brake engaging sequence, the current switches to 0 in accordance with the ramp [current ramp time] (brr) after the expiry of the
time [brake engage time] (bEt) .
[BRH b2] (brH2) = 1: When the brakes are released, the reference is unlocked when the logic input changes to 1. On closing, in accordance
with [current ramp time] (brr) , the current switches to 0 if the logic input changes to 0.

brH3 [BRH b3] 0
Only available in the closed control loop. Management of missing brake contact response, if assigned.
0 [0] (0) : During the brake engaging sequence, the brake contact must be opened before the end of the [brake engaging current] (bEt) , or the
inverter will be locked in an A brake contact fault brF .
1 [1] (1) : During the brake engaging sequence, the brake contact must be opened before the end of the [brake engaging current] (bEt) , or a bCA
brake contact alarm will be triggered and zero speed will be maintained.
brH4 [BRH b4] 0
Only available in the closed control loop. Activation of the speed controller at zero when a motion occurs for which no command has been issued
(when measuring a speed over a fixed minimum threshold).
0 [0] (0) : No action if a movement occurs for which no command has been issued.
1 [1] (1) : If a movement occurs for which no command has been issued, the inverter shuts down to zero speed control without brake release
command and a bSA alarm is triggered.
brr [Current ramp time] 0 to 5 s 0 s
Time of the ramp for the torque current (increase and decrease) for a current change that corresponds to the value [I brake engaging upw.] (Ibr) .
Parameter that can be modified during operation or when stopped.
