PI-/PID control switch-over position droop
Setting the switching threshold of the contouring error (in pulses) for the switch-over from PI to PID control.
Set "0001" in parameter No. 32 to make this function valid.

Pulse/r
Encoder simulation resolution
Setting the number of pulses (A-phase, B-phase) which is output for a complete revolution of the motor at the
simulated encoder output.
The number of A-phase and B-phase pulses actually output is 1/4 times greater than the preset number of pulses.
Therefore, set the value 4 times greater than the desired pulses.You can use parameter No. 33 to adjust the output
pulse. The maximum output frequency is 1.3Mpps (after multiplication by 4).
Setting example:
With pr. 33 the direct pulse output is selected (contents of pr. 33: 0mmm). For a target in pr. 38 of 5600, for one
revolution of the motor 5600/4 = 1400 pulses are output.
Parameter 33 is set so that (contents of pr. 33: 1mmm), the pulses that are produced for a full rotation of the motor,
are divided by the figure specified in pr. 38.
If, for example, the figure “8” is specified in parameter 38, then for one revolution of the motor (131072/8) × 1/4 =
4096 pulses are output.
