Switching thresholds
Upper speed threshold for brake release:
Switching threshold (
) + hysteresis for release (
)
Lower speed threshold for brake application:
Switching threshold (
) - hysteresis for application (
Note!
In
, 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
– 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.
Stop!
Do not set the lower speed threshold for brake application too high to prevent
an excessive wear of the brake!
Note!
For the speed comparison, only the absolute motor speed value is considered,
the direction of rotation is not taken into account.
Avoid a conflict between the mechanical holding brake and the "
" function by setting the auto-DCB threshold (
) to 0 rpm for DC-
injection braking.
