Position Detection and Positioning
Modulo short route (note: when MOD.TAGPOS = 120° the axis only moves in a coun-
terclockwise direction when the drive is positioned at least 1 increment CCW of 300°,
since 300° + 180° = 120° and 300° 180° = 120°).
Therefore, to position an axis that is at 0°, 1 revolution in a clockwise direction, H454
must be set to 0x 10000. To move this axis 1 revolution CCW, H454 must be set to 0x
FFFF0000.
"CW" Modulo mode "CW" (P960 = CW)
The drive moves from the current actual position H455 MOD.ACTPOS clockwise to the
target position H454 MOD.TAGPOS.
Target position that can be represented:
H454 MOD.TAGPOS = k × 360° + 0 ... 360° = k × 2

+ 0 ... (2

- 1)
Only positive values are permitted in the high part. If this condition is not met and the
sign bit 2
32
is set, the drive inverter displays the fault status (IPOS
plus®
program error).
