8.2.2
“NPE“ Bit 6 in Status Byte 1
This status bit will be set if the drive is within a window of +/- 8 increments around the reference point after the command
“go to reference point”. When leaving this range, the bit will be erased. The drive goes to the reference point in conjunction
with control byte 1 bit 7 and the positioning speed (parameter 12). In order to stop exactly at the reference point the
positioning speed should be as low as possible.
8.2.3
“P1E, P1A, P2E, P2A, P3E, P3A“ in Status Byte 2
Status bits “PxE“ with increasing edge and “PxA“ with falling edge will be set for the corresponding position. These bits
are preserved until the next change of status of the respective position. Furthermore, the bits can be used for triggering an
interrupt (synchronization with position...).
8.2.4
“PSYN“ Bit 7 in Status Byte 1
This status bit is set after the position transmitter has been synchronized. Then the value in parameter E0 as well as all other
status signals of the positions are valid.
8.2.5
“P2T“ Bit 0 in Control Byte 2
If this bit has been set, a single impulse (LOW – HIGH – LOW) is issued at the output of position 2. This command will
only be executed at standstill. The bit is reset after issuing this impulse or whenever the drive has not stopped.
8.2.6
“2N“ Bit 1 in Control Byte 2
If this bit is set, the speeds are doubled. The quadruple speed must now be transmitted. Internally, the speed is limited to
10000 RPM. The positioning speed will not be doubled.

8.2.7
“ZSTP_“ Bit 2 in Control Byte 2
If this bit is set, accurate positioning is disabled. The drive stops out of the positioning speed (parameter 68).
8.2.8
“PNLIM“ Bit 5 in Control Byte 2
At this setting the speed is limited if the pedal speed is higher. The pedal speed has priority if it is lower than this limit.
8.3 Functional Descriptions
8.3.1
Stop Segment Angle for Positioning (System -values C, Group 7)
An angle with which the stop point can be moved backward depending upon the set stop position can be set by means of
parameter 72. The positions (1E, 1A, 2E, 2A, 3E, 3A) will not be changed.
The preset value for parameter 72 is 0. The maximum value is 50 increments (e. g. 50 * 1.4° = 71.1°) and can be changed
in single increments. Transmission is done at 2 bytes.
