144
Gain AC brake
Value:
1.00 - 1.50
1.30
Function:
This parameter is used to set the AC brake. Using par.
144 it is possible to adjust the size of the generator
torque that can be applied to the motor without the
intermediate circuit voltage exceeding the warning
level.
Description of choice:
The value is increased if a greater possible brake tor-
que is required. If 1.0 is selected, this corresponds to
the AC brake being inactive.
Please note
146
Reset voltage vector
Value:
*Off
(OFF)
[0]
Reset
(RESET)
[1]
Function:
When the voltage vector is reset it is set to the same
starting point each time a new process commences.
Description of choice:
Select reset (1) when running unique processes each
time they arise. This will enable repetitive precision
when stopping to be improved. Select Off (0) for ex-
ample for lifting/lowering operations or synchronous
motors. It is an advantage that the motor and the fre-
quency converter are always synchronized.

NOTICE
If the value in par. 144 is increased, the motor current
will simultaneously increase significantly when genera-
tor loads are applied. The parameter should therefore
only be changed if it is guaranteed during measurement
that the motor current in all operating situations will nev-
er exceed the maximum permitted current in the motor.
: that the current cannot be read out from
the display.
