Parameters
P2.083
Default: 2000
8
Format: DEC
Settings:
This parameter detects if the motor encounters a new Z signal when operating. It is suggested that you
set this parameter as half the number of pulses between two Z signals.
This parameter is only applicable to pulse linear motors and when PM.003.U is set to 1 (main encoder
connects to CN5). You can disregard this parameter if there is only one Z signal.

When the resolution of the motor is low, enable this function to
smooth the uneven speed. This function is only applicable to pulse
motors and when PM.003.U is set to 1 (main encoder connects to
CN5).
0: disable
1: enable
-
When the resolution of the motor is low, enable this function to
smooth the speed with a filtering effect. Before this function is
enabled, it is suggested that you gradually lower the set value for
P2.025 to avoid sacrificing the phase due to excessive filtering and
thus resulting in resonance of the machine.
0: speed observer 1; the filter bandwidth is 1000/P2.049.
1: speed observer 2; the filter bandwidth cannot be adjusted.
2: speed observer 3; the filter bandwidth is 1000/P2.049.
Note:
1. Speed observer 1 is applicable to high resolution encoders.
2. Speed observers 2 and 3 are applicable to encoders or linear scales with
low resolution. For example, the single-turn resolution of the rotary encoder
is smaller than 40000 pulse/rev and the application requires low speed
(lower than 100 rpm), or the resolution of the linear encoder is greater than
5 μm/pulse.
