Overview

2.3.1
The iC speed profile is used with the iC7 series motor applications. The 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.

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 drive to immediately coast the motor.
1: No function.
0: Quick stops the drive and ramps down the motor speed to stop as de-
fined 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
drive to start the motor.
0: Stops the drive 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.
