Modulo function
Position Detection and Positioning
"CCW" Modulo mode "CCW" (P960=CCW)
The drive moves from the current actual position H455 MOD.ACTPOS counter-clock-
wise to the target position H454 MOD.TAGPOS.
Target position that can be represented:
H454 MOD.TAGPOS = - k × 360° + 0 ... 360° = - k × 2
16
+ 0 ... (2
16
- 1)
Only negative values are permitted in the high part. If this condition is not met and the
sign bit 2
32
is not set, the drive inverter displays the fault status (IPOS
plus®
program
error).
