134.6 Speed limit
Threshold value for speed-dependent engagement of the motor holding brake in the Au-
tomatic mode (Z134.1– Bit 0 = 1). The brake is applied in the following cases as soon as
the magnitude of the instantaneous speed has fallen below the threshold value:
m Drive is actively braking (hold on ramp)
m Drive is without torque (pulses are inhibited, Z134.3– Bit 2 must be 1)
134.7 Timeout check-back signal
Timeout for evaluating the state response signal. If the expected brake state (enabled/en-
gaged) is not detected within the timeout period, an error reaction is initiated.
134.8 Pulse inhibit delay
Delay to allow for the brake engagement time and, where necessary, the dead time due
to a relay in the Automatic mode (
Z134.1– Bit 0 = 1). After the brake is applied during an
active braking procedure (e.g. Quick Stop on ramp) the pulses are inhibited at the earliest
after the time set in 134.8 has elapsed. Hence it can be ensured that the drive will only
be without torque once the holding brake has built up the full mechanical braking force:
m The evaluation of the brake state is switched off (Z134.1– Bit 4 = 0):
The pulse inhibit occurs at the earliest after the time set in 134.8 has elapsed following
the issue of the engage command by the drive manager.
m The evaluation of the brake state is switched on (Z134.1– Bit 4 = 1):
The drive is without torque at the earliest after the time set in 134.8 has elapsed follow-
ing reception of the "Brake is engaged" confirmation.

134.9 Start of motion delay
Delay to allow for the brake enable time and, where necessary, the dead time due to a
relay in the Automatic mode (
Z134.1– Bit 0 = 1). After the brake is enabled an accelera-
tion takes place at the earliest after the "Start of motion Delay" time set in Automatic mode
(
Z134.1– Bit 0 = 1). Hence it can be ensured that the drive is not working against the
holding brake which is possibly not yet fully enabled:
m The evaluation of the brake state is switched off (Z134.1– Bit 4 = 0):
The acceleration occurs at the earliest after the time set in 134.9 has elapsed following
the issue of the enable command.
m The evaluation of the brake state is switched on (Z134.1– Bit 4 = 1):
The drive is without torque at the earliest after the time set in 134.9 has elapsed follow-
ing reception of the "Brake is enabled" confirmation.
