8.4.2.2 Functional settings
The following bit coded functional settings for the holding brake control can be made in C02582 :

Bit Option Info
Bit 0 bBrkReleaseOut invert. Activation of inverted control
• "1" ≡ Inverted logic of the trigger signal for the holding brake
control switching element
Bit 1 [--]: nAct < nMin at CInh Brake response in case of pulse inhibit
• "1" ≡ In the case of a pulse inhibit, the actual speed value is
monitored which must reach the "Close" threshold value to cause
the holding brake to be applied.
Note:
• This function is only active if bit 3 (horizontal/winding
technology) is set as well. The function is used in order that, when
the controller is inhibited, the holding brake of a drive with
horizontal traverse path does not wear out during rotation.
• With vertical motion (bit 3 = 0), this function is not active.
Especially with hoists and activated pulse inhibit of the controller,
an immediate application of the brake is essential for safety-
related reasons!
Bit 2 [||]: Feedforward control inverted Direction of feedforward control with vertical/hoist technology:
• "0" ≡ Positive direction
• "1" ≡ Negative direction
Note:
Reversal (Ccw) is then considered.
Bit 3 [--]: Horizontal Direction of movement of the axis
• "0" ≡ The axis performs vertical movements. Gravitational
acceleration causes movements.
• "1" ≡ The direction of the axis is horizontal or rotary. The
gravitational acceleration does not cause any movement.
Bit 4 Reserved
Bit 5 Reserved
Bit 6 Sync ramp L_NSet_1
(from version 11.00.00)
Selection of the ramp time for the synchronisation process to
setpoint speed after the brake opening time has elapsed
Revised behaviour from version 11.00.00:
• "1" ≡ The ramp time of the effective acceleration of the ramp
function generator ( L_NSet_1 ) is used (Lenze setting).
• "0" ≡ As before, the ramp time set in C02610/1 is used.
Note:
The changeover can be dynamically both via the ramp parameter
and via bit 6.
Bit 7 Reserved
