In case of stop with spin out, during this time an
other start command remains ineffective, for
disabling a restart.

unit cannot be restarted.

DC brake
The 6-4 motor nominal current (In) parameter overrules the brake current. Even with setting
larger current, the frequency converter permits the nominal current of the motor as a maximum!
The operation of the DC brake is shown in the status display ("DC brake").

In case of activating from digital input, also current values differing from this can be
set (4-9-3 continuous DC brake current).

3-8-2 changing frequency
With mixed stop (3-5 stop mode), above the
switch-over frequency the normal brake, below it
the DC brake will be effective. At higher
frequencies the DC brake is not so effective.

resistor brake
Without being equipped with resistor brake, at generator mode (e g. at fast deceleration) the
frequency converter limits the gradient of slope, if it is needed for providing secure stopping!
If the resistor brake is enabled, its operation is shown in the state display („R brake”)!
3-9-1 permission
yesVent: In case of start the frequency converter
turns on also the ventilator. After expiry
of the start state, the ventilator operates
for further 2 minutes. In case of
connecting a brake module with
ventilator, the ventilators of the brake
resistor can work together with the
ventilators of the equipment.

brake operation
After the motor stopped, for the time set here,

permitting time for activating a possible
