2.2.1 iC Speed Profile

The iC Speed profile is used with the iC7 series. iC Speed profile differs from the PROFIdrive profile, because it does not have a state
machine. It is only controlled by the actual state 1/0 of the control bits, not the sequence in which they are manipulated.

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 = Causes the frequency converter immediately to coast the motor.
1 = No function.
0 = Quick stops the frequency converter and ramps down the motor speed to stop as defined in the
quick-stop ramp parameter.
1 = No function.
0 = Holds the present output frequency (in Hz).
1 = If the other starting conditions are fulfilled, the selection allows the frequency converter to start
the motor.
0 = Stops the frequency converter and ramps down the motor speed as defined in the ramp-down
parameter.
0→1 = Acknowledge faults.
Acknowledge is edge-triggered, when logic is changed from 0 to 1. Faults can only be acknowl-
edged if the trigger condition has been removed and any required acknowledgment has been
done.
0 = No function.
1 = Sets the output frequency to the jog speed defined in the jog speed parameter.
0 = No function.
1 = Ramp 2 is active.
0 = Ramp 1 is active.
