0…1000 ms Position reference filter time for position reference set 1.
65.09 POS STYLE 1 FW block: PROFILE REF SEL (see above)
Determines the behaviour of the position profile generator when position reference set 1 is used. The
figures below display the behaviour of each bit (different bit combinations are also possible).
Bits 0…2 determine in which way the drive moves to an additional position reference or corrects the
synchronisation error (caused by position reference limitation or cyclic correction) in synchron control
mode. Only one of these bits can be active at a time.
The positioning priority order is:
1) bit 2 or according to the linear axis positioning selected by par.
60.02 POS AXIS MODE .
2) bit 0
3) bit 1.
Conversion from binary to hexadecimal format examples:
Bits 3…6 determine the path to the target position.
Bit 7 provides one revolution positioning in the roll-over mode.
0b0000000…0b1111111 Positioning style for position reference set 1.
Bit 0 1 = Positioning direction depends on the direction of the synchronous (master) speed.
0 = Positioning direction is independent of the synchronous (master) speed.
Bit 1 1 = Counter-clockwise positioning to the target position (bit 0 = 0).
or positioning in the opposite direction to the synchronous (master) speed when bit 0 = 1.
0 = Clockwise positioning
to the target position (bit 0 = 0).
or positioning in the direction of the synchronous (master) speed when bit 0 = 1.
