Modes of Operation Chapter 10
The following table shows the command source selection.
•Status of DI.SPD0
and DI.SPD1 signals: 0 means that DI is off, and 1
means that DI is on.
• In Sz mode, the command is 0 when both DI.SPD0 and DI.SPD1 signals
are 0. Thus, if the speed command that is using an analog voltage type is
not required, you can use Sz mode to address the problem of zero drift in
the voltage.
If it is in S mode, the command is the voltage deviation between V-REF
and GND. The range of the input voltage is between -10V and +10V, and
you can adjust the Analog to Speed Scale ID147 (P1.040) parameter. For
more information, see Scaling the Analog Command (Speed Mode)
on
page 215.
• When either DI.SPD0 or DI.SPD1 signal is not 0, the Speed command
comes from the internal register. The command is activated once the status
of DI.SPD0 and DI.SPD1 signals are changed. There is no need to use the
DI.CTRG signal for triggering.
• The parameter setting range (internal register) is -60000…+60000.
Setting value = setting range x unit (0.1 rpm).
For example:
If ID125 (P1.009) = 30000,
then rotation speed = 30000 x 0.1 rpm = 3000 rpm
The speed command can also come from the controller when Operating Mode
ID117 (P1.001) is set to 0xC (I/O mode). The command name is Target Speed.
See I/O Mode - Speed
on page 241.
