Program features 101
Notes:
• DC hold is only available in speed control in DTC motor control mode (see page
).
• The function applies the DC current to one phase only, depending on the position
of the rotor. The return current will be shared between the other phases.
Post-magnetization
This feature keeps the motor magnetized for a certain period (parameter
) after stopping. This is to prevent the machinery from moving
under load, for example before a mechanical brake can be applied. Post-
magnetization is activated by parameter
. The magnetization
Note:
Post-magnetization is only available in speed control in DTC motor control
mode (see page
), and only when ramping is the selected stop mode (see
parameter
).
Continuous magnetization
A digital signal, such as a user bit in the fieldbus control word, can be selected to
activate continuous magnetization. This can be especially useful in processes
requiring motors to be stopped (for example, to stand by until new material is
processed), then quickly started without magnetizing them first.
Note:
Continuous magnetization is only available in speed control in DTC motor
control mode (see page
), and only when ramping is the selected stop mode (see
parameter
).
