Description
This bit indicates that the module is ready to receive values from the user program for control-
ling the pulse output.
This bit indicates one of the following situations:
• Actual speed value ≥ configured maximum speed
• Actual speed value < 0.1 Hz
This bit indicates that the pulse output is ready to switch on.
This bit indicates that the pulse output is ready to operate.
This bit indicates that operation of the drive is enabled and the speed setpoint is being output.
This bit indicates that an error has occurred on a digital output. Error code 1
This bit indicates that the drive will not perform a Coast Stop (OFF2).
This bit indicates that the drive will not perform a Quick Stop (OFF3).
This bit indicates that the pulse output is not yet ready to switch on.
This INT value indicates the actual value of the drive velocity as a percentage in N2 format
relative to the reference speed. The N2 format is described with the NSOLL_A control value
(Page 30).
This value is set to 0.
With Mode = 1 (Measurement on the fly), this bit indicates the status of the digital input
CHn.MI.
This bit indicates that the acknowledgment of an error is being processed.
This bit indicates that one of the following situations has occurred:
• The Activate_Parking_Sensor control bit is enabled.
• The module does not supply a valid position, for example, because the internal logic is not
yet ready or a fault occurred in the supply voltage.
The Control_Requested bit is reset in this case.
This bit indicates that an error has occurred during feedback of position value G1_XIST1. The
meaning of the returned error codes in G1_XIST2 can be found in the following table.
Mode = 0 (Reference mark search):
This bit indicates that the use of the reference switch input CHn.RS is activated.
Mode = 1 (Measurement on the fly):
This bit indicates that the use of the rising edge of the CHn.MI measuring input is enabled.
This bit indicates that use of the negative edge of measurement sensing input CHn.MI is ena-
bled.
