Goodrive350 IP55 High-ingress Protection Series VFD
determined by the acceleration /deceleration time of pulse train, the pulse train
acceleration/deceleration time of the system can be adjusted. If the pulse train acts as the
frequency source in speed control, you can also set P21.00 to 0000, and set the frequency
source reference P00.06 or P00.07 to 12 (Pulse train AB), at this point, the
acceleration/deceleration time is determined by the acceleration/deceleration time of the
VFD, meanwhile, the parameters of pulse train AB is still set by P21 group. In speed mode,
the filter time of pulse train AB is determined by P21.29.
(8) The input frequency of pulse train is the same with the feedback frequency of encoder
pulse, the relation between them can be changed by altering P21.11 (Numerator of position
command ratio) and P21.12 (Denominator of position command ratio).
(9) When running command or servo enabling is valid (by setting P21.00 or terminal function
63), it will enter pulse train servo running mode.
4. Commissioning procedures for spindle positioning
Spindle orientation is to realize orientation functions like zeroing and division based on
closed-loop vector control.

(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, thus realizing spindle positioning function in either position control
or speed control mode.
(5) Set P22.00.bit0=1 to enable spindle positioning, set P22.00.bit1 to select spindle zero input.
If the system adopts encoder for speed measurement, set P22.00.bit1 to 0 to select Z pulse
input; if the system adopts photoelectric switch for speed measurement, set P22.00.bit1 to 1 to
select photoelectric switch as zero input; set P22.00.bit2 to select zero search mode, set
P22.00.bit3 to enable or disable zero calibration, and select zero calibration mode by setting
P22.00.bit7.
(6) Spindle zeroing operation
a) Select the positioning direction by setting P22.00.bit4;
b) There are four zero positions in P22 group, you can choose one out of four zeroing
positions by setting zeroing input terminal selection (46, 47) in P05 group. When
executing zeroing function, the motor will stop accurately at corresponding zeroing
position according to the set positioning direction, which can be viewed via P18.10;
