Following error detection

The

0x6065

object (following error window) defines a symmetrical tolerance window

around the position setpoint for the purpose of following error detection.

 If the tolerance window is set = "0", the following error detection is deactivated.
 If the tolerance window is set > "0", the following error detection is activated, i.e. a

following error will be detected if the position value is outside this tolerance window.

 For activated following error detection: If the following error is detected for a longer

time than the time in [ms] defined in object

0x6066

(following error time out),

– bit 13 ("following error") is set in object

0x6041

(statusword).

– the error response set in object

0x60FB/4

(following error reaction) is triggered.

– the "Following error" error message (with error number 0x3B40001) is entered into

the logbook.

Tip!
The

0x60F4

object (following error actual value) shows the current deviation of the

actual position value from the position setpoint.

3.10.5

In-position recognition

The

0x6067

object (position window) defines a symmetrical tolerance window around the

target position for the purpose of in-position recognition.

 If the actual position value is inside this tolerance window, the target position is

deemed to be reached and bit 10 ("target position reached") is set in the

0x6041

object

(status word).
