Description
00 = Preset reference 1
01 = Preset reference 2
10 = Preset reference 3
11 = Preset reference 4
Reserved for future use.
Any control words sent to the device should keep this bit at 0 to ensure
compatibility with future extensions of the control word.
1 = No function.
0 = Cause the frequency converter to immediately coast the motor.
1 = No function.
0 = Quick stop the frequency converter and ramp down the motor speed
to stop as defined with the quick stop ramp parameter.
1 = No function.
0 = Hold the present output frequency (in Hz).
1 = If the other starting conditions are fulfilled, this selection allows the
frequency converter to start the motor.
0 = Stop the frequency converter and ramps down the motor speed as
defined with the ramp down parameter.
0 ⇒ 1 = Acknowledge faults.
Acknowledge is edge-triggered, when the logic is changed from 0 to 1.
Faults can only be acknowledged is the triggering condition has been re-
moved and any required acknowledgment has been done.
0 = No function.
1 = Set the output frequency to the jog speed defined with the jog
speed parameter.
0 = No function.
1 = Ramp 2 is active.
0 = Ramp 1 is active.
1 = Use process data (control by PLC).
0 = Ignore the current process data. This is linked to the submodule
where the CTW is present. If signals are to be covered, the CTW/STW pro-
file (the iC Speed Profile for example) must be part of the signals list.
Use the previously processed data when the data valid bit was true (no
control by PLC).
Reserved for future use.
