mode
Signal name, description PROFIBUS bitposn–setFct. No.
Selection, parking axis 40 x x STW2.7
The drive can be declared a ”parking axis”, using this input signal.
1 signal ”Parking axis” selected
The parking axis selection is only activated when the pulses are canceled or the controller
is inhibited with subsequent pulse cancellation (e.g. using terminal 663, 63, 65.x, control
signal ON/OFF 1) (refer to the output signal ”parking axis selected”).
The encoder–specific monitoring functions are suppressed for a parking axis.
The output signal ”reference point set” is withdrawn.
0 signal ”Parking axis” canceled
The monitoring functions are active corresponding to the setting in P1600.
Application:
It is possible to change over from one motor encoder unit to another unit using the ”parking axis” function,
without having to power down the drive.
Note:
After the ”parking axis” function has been canceled, the following is valid:
 Incremental measuring system: The axis must be re–referenced (refer to Chapter 6.2.5).
 Absolute measuring system (EnDat): The axis must be re–adjusted (refer to Chapter 6.2.7).
The adjustment status cannot be withdrawn by just selecting or canceling the ”parking axis” function.
This status is only permanently withdrawn when an another absolute value encoder has also been auto-
matically detected.
Opening the holding brake for test purposes (from
SW 4.1)
42 x x STW1.12
A holding brake can be opened for test purposes during the commissioning phase using this input signal.
1 signal The function is activated
0 signal De–activates the function
Note:
This input signal is only evaluated if the brake control is activated using P0850 = 1. In the operating
mode, the brake is controlled using P0850 (operating sequence control) and not via this input signal.
