Frequency threshold for
DC-injection
Range: 0.2…5.0 Hz
Default setting 1.00 Hz
F602
Intensity DC-Brake START

Default setting 10
F603
Intensity DC-Brake STOP
F604
DC-Brake duration START
Range: 0.0 - 30.0 sec.
Default setting 0.5 sec.
F605
DC-Brake duration STOP
DC Brake can be used as an alternative to ramp controlled STOP
(F209=2).
Intensity is controlled by
(F603),
duration by
(F605)
.
Attention!! Improperly programmed DC-Brake function may result in inverter overcurrent
trip and/or motor overheating
In case of braking by DC injection all kinetic energy will be dissipated in the motor rotor.
Repeatedly use of the DC brake function may result in motor overheating
Message "DC-Brake active" may be configured through digital output – assignation code

Current- Voltage limiting functions
Limiting functions for current and voltage are available in standard E2000 inverters
Current limiting function: To program a motor current threshold. If motor current reaches the threshold (F608) during
acceleration, the acceleration ramp will delay, until current drops below the limit.
If current exceed the limit at target frequency (ramp completed), the frequency will be reduced, if necessary, down to
the minimum frequency.
Current limiting function is always deactivated during deceleration ramp.
Voltage limiting function: To limit the DC-link voltage increase, due to energy regeneration during deceleration phase.
If voltage reaches the limit (F609), the limiting function will stretch the deceleration ramp.
The limiting status of the inverter can be signalized through any programmable digital output. Aassignation code:
