RUN
Ad.42
[13]
Delay before
brake opening
1.00s
0.00 to
10.00s
Once the motor current is greater than the
one set in parameter Ad.41 and the
frequency reached in the motor is the same
as the one set in parameter Ad.44, the drive
will open the relay configured as ‘BRCtrl’ and
will keep this speed during the time
established in this parameter.
NO
Ad.44
[13]
Brake opening
forward
frequency
1.00Hz 0.00 to
dr.20
Set the brake opening frequency of the relay
configured as ‘BRCtrl’ while the motor is
accelerating in positive direction.
NO
Ad.45
[13]
Brake opening
reverse
frequency
1.00Hz
0.00 to
dr.20
Set the brake opening frequency of the relay
configured as ‘BRCtrl’ while the motor is
accelerating in negative direction.
NO
Ad.46
[13]
Delay before
brake closing
1.00s
[13
0.00 to
10.00s
Once the motor has reached the frequency
set in Ad.47, the drive will close the braking
relay and will keep this speed during the time
established in this parameter.
NO
Ad.47
[13]
Brake closing
frequency
2.00Hz
0.00 to
dr.20
Set the frequency value at which the braking
relay will stop operating, allowing the closed
brake function.
NO
Ad.50
Minimum flux
mode
NONE 0 to 2
Set the minimum flux that the motor can
employ to operate under low load conditions.
With this optimized flux system, noises and
power losses will be reduced due to the
automatic flux level arrangement. The
following table shows the different available
configurations:
OPT. DESCR. FUNCTION
0 NONE No action is executed
1 MANU
Selects the manual mode.
If the output current is
lower than the parameter
bA.14 (no load motor
current), output voltage
will be reduced in the
magnitude
set in
parameter Ad.51.
2 AUTO
Selects the automatic
mode. The output voltage
is set taking into account
the motor rated current
set in bA.13 and bA.14.
NO
