AKD 5000
Function:
Here it is possible to select the function of the frequency
converter after a stop command or when the frequency
has been ramped down to 0 Hz. See parameter 123
with respect to activation of this parameter regardless
of whether the stop command is active.
Description of choice:
Select
Coasting
[0] if the frequency converter is to
’
let go
’
of the motor (inverter closed).
Select
DC hold
[1] when a DC holding current set
in parameter 124 is to be activated.
Select
Motor check
[2] if the frequency converter is to
check whether or not a motor has been connected.
Select
Pre-magnetizing
[3]. The magnetic field
is built up in the motor while it remains stopped.
This ensures that the motor can produce torque
as quickly as possible on starting.
124 DC holding current
(DC-HOLD CURRENT)
Value:
✭
0 %
Function:
This parameter is used to uphold the motor function
(holding torque) or to pre-heat the motor.
NB!:
The maximum value depends on the rated
motor current. If the DC holding current
is active, the frequency converter has a
switching frequency of 4 kHz.
Description of choice:
This parameter can only be used if
DC hold
[1] has
been selected in parameter 121 or 122. Set it as
a percentage value in relation to the rated motor
current I
M,N
set in parameter 105.
100% DC holding current corresponds to I
M,N.
Warning: 100 % supply for too long
may damage the motor.
125 DC braking current
(DC BRAKE CURRENT)
Value:
✭
50 %
Function:
This parameter is used for setting the DC brake
current that is activated upon a stop when the DC
brake frequency set in parameter 127 has been
reached, or if the DC brake inverse is active via digital
terminal 27 or via a serial communication port. The
DC braking current will be active for the duration of
the DC braking time set in parameter 126.
NB!:
The maximum value depends on the rated
motor current. If the DC braking current
is active, the frequency converter has a
switching frequency of 4.5 kHz.
Description of choice:
To be set as a percentage value of the rated motor
current I
M,N
set in parameter 105.
100% DC braking current corresponds to I
M,N
.
Warning: 100 % supply for too long
may damage the motor.
126 DC braking time
(DC BRAKING TIME)
Value:
0.0 (OFF) - 60.0 sec.
✭
10.0 sec.
Function:
This parameter is for setting the DC braking time
for which the DC braking current (parameter
125) is to be active.
Description of choice:
Set the desired time.
127 DC brake cut-in frequency
(DC BRAKE CUT-IN)
Value:
0.0 - parameter 202
✭
0.0 Hz (OFF)
Function:
This parameter is for setting the DC brake cut-in
frequency at which the DC braking current (parameter
125) is to be active, in connection with a stop command.
