Goodrive35 inverters
(8)The input frequency of the pulse train is the same as the feedback frequency of the encoder pulse.
The relationship between them can be changed by modifying P21.11 and P21.12.
(9)When run command or servo enable is valid by setting P21.00 or terminal function 63, the inverter
will run into the pulse string servo mode.
4. Debugging steps of spindle positioning
The spindle positioning is the function of stopping such as zeroing and scaling on the basis of close
loop vector control.

The steps of (1) – (4) are the same as the 4 steps in close-loop vector control mode. The function of
spindle positioning is available in the position control mode and speed control mode.
(5) Set P22.00.bit0=1 and P22.00.bit1. If the system applies encoder to detect the speed, set
P22.00.bit1=0, and if the system applies the photoelectric switch to detect the speed, set
P22.00.bit1=1; set P22.00.bit2, P22.00.bit3 and P22.00.bit7
(6)Spindle zeroing
a) Set P22.00.bit4 to select the positioning direction.
b) There are 4 zero positions in P22 group. Set P05 to select the zeroing position. Operation on
P18.10 can watch the stopping state.
c) The positioning length is determined by the deceleration time and the deceleration speed.
(7) Spindle scaling
There are 7 scale positions in P22 group. Set P05 to select the scale position. Enable corresponding
terminal after motor stopping, the motor will inquiry the scaling state and turn to corresponding
position. Operation on P18.09 can watch the state.
(8) Priority of the speed control, position control, zeroing and scaling
The priority of speed control > The priority of scaling
If the system runs at the scaling mode, when the spindle positioning is disabled, the motor will runs at
