2 Parameters
2.2 List of parameters
p50086 Sequence control line voltage failure duration permissible / V_line_fail t perm
DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.00 [s]
Description: Sets the permissible duration of a line voltage failure.
If a line voltage failure lasts longer than this time, the corresponding fault will be triggered.
If the line voltage failure is shorter than the set time, a restart will follow automatically.
Dependency: Refer to: F60004, F60005, F60006, F60007, F60008, F60009
Caution: The value in p50090 must be smaller than that in p50086 (unless for a value = 0.0) and in p50089!
p50087

Brake control brake opening time / Br ctr t open

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
-10.00 [s]
Description: Sets the brake closing time.
When "Open brake" is sent, the firing pulse enable is delayed by this time.
Note: For a negative time setting:
With "Open brake", a delay corresponding to the set time is applied in relation to the enable for the firing pulses for
the thyristors. During this time, the motor works in opposition to the brake, which is still closed. This is useful, for
example, in the cases of suspended loads.
For a positive time setting:
When the "Switch on", "Jog" or "Creep" command is sent with operation enabled, the firing pulses for the thyristors
are not enabled until the set time has elapsed. During this time, the drive is in operating state o1.0 to give a holding
brake the opportunity to open in advance.
p50088

Brake control brake closing time / Br ctr t close

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.00 [s]
Description: Sets the brake closing time.
When "Close brake" is sent, the firing pulse inhibit is delayed by this time.
Note: During this time, the drive is in operating state o1.1, o1.2, or o1.0 and is still applying torque.
p50089

Sequence control voltage at power unit wait time / S ctr V at PU t

DC_CTRL Can be changed: U, T
Data type: FloatingPoint32
P-Group: -
Not for motor type: -
Min
0.01 [s]
Description: Sets the wait time for voltage and field current at the power unit.
