External speed limitation
The External speed limitation function limits the speed reference to a predefined
value when an external speed limit signal is activated. You can define the speed
limits in parameters
MAX EXT LIM SPD and
MIN EXT LIM SPD, while
the external speed limit signal has to be configured in parameter
LIM PTR. The speed limit signal is a pointer parameter, and hence, it can be
configured to a DI, PLC DI using fieldbus communication or to any other signal bits.
When the speed limit signal is activated, the drive speed reference is limited to
MAX EXT LIM SPD if the motor is running in the forward direction or to
EXT LIM SPD if the motor is running in the reverse direction. The limitation status
can be monitored using bits
bit 10 for
maximum external speed limit and
bit 11 for
minimum external speed limit.
