encoder and the magnetic pole position of the motor.
Setting range: 0.00–359.99
Setting range: 0–3
0: No operation
1: Rotary autotuning (no load)
2: Static autotuning (fit for resolver and sin/cos
encoder)
3: Rotary autotuning (loaded)
After setting the value to 1 or 2, the keypad will
display "-RUN-", then press "RUN" to begin the
autotuning until the keypad display "-END-". The
identified initial angle is saved in P20.09 and P20.10.
The pole initial angle obtained from rotary autotuning
1 is more accurate. Generally it is necessary to
de-couple the motor or lighten the motor load for
rotary autotuning.
Range: 0.0–20.0us
0: Disabled
1: Enabled
Setting range: 0x00–0x21
Ones: Control mode setting, setting the position
control mode in closed-loop vector control.
0: Speed control
1: Position control
Tens: Position command source
0: Pulse string, adopting terminal pulse signals A2
and B2 to implement positioning control
1: Digital position. Positioning through P21.17 and
the positioning modes can be set through P21.16
2: Photoelectric switch positioning. After the terminal
receives the signal (set S8 to 43), the stopping
positioning begins and the stopping distance is set
through P21.17.
Hundreds: Reserved
