Goodrive350-19 series VFD for crane Basic operation guidelines
Proximity switch positioning supports the following spindle positioning modes:
d) The encoder is installed on the spindle, and the motor shaft is connected to the spindle with belt,
the drive ratio is not necessarily 1:1;
at this time, you need to set P22.14 (spindle drive ratio).
5. Commissioning procedures for digital positioning
The diagram for digital positioning is shown as follows.

P21.25 Hold time of positioning completion signal
(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.
(5) Set P21.00=0011 to enable digital positioning. Set P21.17, P21.11 and P21.12 (to set positioning
displacement) according to actual needs; set P21.18 and P21.19 (to set positioning speed); set
P21.20 and P21.21 (to set ACC/DEC time of positioning).
(6) Single positioning operation
Set P21.16.bit1=0. Then the motor executes a single positioning action and keeps at the positioning
position according to the setup at step (5).
(7) Cyclic positioning operation
Set P21.16.bit1=1 to enable cyclic positioning. The cyclic positioning is divided into continuous mode
and repetitive mode. You can also carry out cyclic positioning through terminal function (no. 55,
enable digital positioning cycle)
6. Commissioning procedures for positioning of photoelectric switch
Photoelectric switch positioning is to realize positioning function based on closed-loop vector control.
