6. Commissioning procedure for positioning of photoelectric switch
Photoelectric switch positioning is to realize positioning function based on closed-loop vector control.

Step 1
–4: These four steps are the same with the first four steps of the commissioning procedures for closed-loop vector
control, which aim to fulfill the control requirements of closed-loop vector control.
Step 5 Set P21.00=0021 to enable photoelectric switch positioning, the photoelectric switch signal can be connected to
S8 terminal only, and set P05.08=43, meanwhile, set P21.17, P21.11 and P21.12 (set positioning displacement) based
on actual needs; set P21.21 (deceleration time of positioning), however, when present running speed is too fast or the
set positioning displacement is too small, the deceleration time of positioning will be invalid, and it will enter direct
deceleration positioning mode.
Step 6 Perform cyclic positioning.
After positioning is done, the motor will stay in current position. You can set cyclic positioning through input terminal
function selection (55: enable cyclic digital positioning) in P05 group; when the terminal receives cyclic positioning
enable signal (pulse signal), the motor will continue running in the set speed as per the speed mode and re-enter
positioning state after encountering photoelectric switch.
Step 7 Hold positioning.
The position loop gain during positioning is P21.03; while the position loop gain in positioning-completion-hold state is
P21.02. In order to keep sufficient position-hold force and ensure no system oscillation occurred, adjust P03.00, P03.01,
P20.05, and P21.02.
