8.2.1.3 Functional settings
The following bit coded functional settings for the holding brake control can be made in C02582 :
Bit Option Info
Bit 0 Control inverted Activation of inverted control
• "1" ≡ Inverted logic of the trigger signal bBrkReleaseOut for
triggering the power output (terminals BR1 and BR2).
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:
• Function only possible if speed feedback via the digital input
terminals DI1/DI2 is available.
 Encoder/feedback system
• 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 Inverted feedforward control Direction of feedforward control with vertical/hoist technology:
• "0" ≡ Positive direction
• "1" ≡ Negative direction
Note:
• Reversal (Ccw) is then considered.
Bit 3 Horizontal/winding technology 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 No premagnetisation From version 02.00.00
Deactivation of the 200 ms premagnetisation before releasing the
brake.
• "0" ≡ Premagnetisation in case of feedforward control.
• "1" ≡ No premagnetisation.
Bit 5 Reserved
Bit 6
Bit 7

Note!
In C00597 , a motor phase monitoring can be set.
• When "1: Fault" is set, it is checked, before the brake is released and during motor
premagnetisation, if all three motor phases are connected. If one or several motor
phases are missing, the brake will not be released and the drive changes to the "Fault"
status.
• If you want to use this function:
• Ensure that the premagnetisation is not deactivated via bit 4 in C02582 .
• Do not release the brake manually via the bBrkRelease input since in this case, no
premagnetisation and thus no check of the motor phases take place.
