246 Parameters
Activates/deactivates the DC hold and post-magnetization
functions. See section
(page
).
Notes:
• These functions are only available in speed control in DTC
motor control mode (see page
).
• DC magnetization causes the motor to heat up. In
applications where long DC magnetization times are
required, externally ventilated motors should be used. If
the DC magnetization period is long, DC magnetization
cannot prevent the motor shaft from rotating if a constant
load is applied to the motor.
0000b
0000b…0011b
DC magnetization selection.
1 = 1
Defines the DC hold speed. See parameter
(page
).
5.00 rpm
0.00 … 1000.00
rpm
DC hold speed.
See par.
Defines the DC hold current in percent of the motor nominal
current. See parameter
, and section
).
30.0%
0.0 … 100.0%
DC hold current.
1 = 1%
Defines the length of time for which post-magnetization is
active after stopping the motor. The magnetization current is
defined by parameter
.
See parameter
0 s
0…3000 s
Post-magnetization time.
1 = 1 s
Continuous
magnetization
command
Activates/deactivates (or selects a source that
activates/deactivates) continuous magnetization. See section
The magnetization current is calculated on the basis of flux
reference (see parameter group
).
Notes:
• This function is only available when ramping is the
selected stop mode (see parameter
), and
only in speed control in DTC motor control mode (see page
• Continuous magnetization causes the motor to heat up. In
applications where long magnetization times are required,
externally ventilated motors should be used.
• Continuous magnetization may not be able to prevent the
motor shaft from rotating during a long period if a constant
load is applied to the motor.
