93.04 ENC1 POS EST ENA
Selects whether position estimation is used with encoder 1 to increase position data resolution or not.
(0) FALSE
(1) TRUE
93.05 ENC1 SP EST ENA
Selects whether calculated or estimated speed is used with encoder 1.
(0) FALSE
(1) TRUE
93.06 ENC1 OSC LIM
Activates transient filter for encoder 1. Changes of direction of rotation are ignored above the selected
pulse frequency.

Parameters and firmware blocks
Channels A and B: Rising and falling edges are used for speed
calculation. Channel B: Defines the direction of rotation. *
Note: When single track mode has been selected by parameter
ENC1 TYPE, setting 0 acts like setting 1.
Channel A: Rising and falling edges are used for speed calculation.
Channel B: Defines the direction of rotation. *
Channel A: Rising edges are used for speed calculation. Channel B:
Defines the direction of rotation. *
Channel A: Falling edges are used for speed calculation. Channel B:
Defines the direction of rotation. *
Used mode (0, 1, 2 or 3) is changed automatically depending on the
pulse frequency according to the following table:
93.03 = 4 93.03 = 5
Used mode
0 0
1 1
2 3
FW block: PULSE ENC CONF
Measured position (Resolution: 4 x pulses per revolution for
quadrature encoders, 2 x pulses per revolution for single track
encoders.)
Estimated position. (Uses position extrapolation. Extrapolated at the
time of data request.)
FW block: PULSE ENC CONF
Last calculated speed (calculation interval is 62.5 µs...4 ms).
Estimated speed (estimated at the time of data request) Estimation
increases the speed ripple in steady state operation, but improves the
dynamics.
FW block: PULSE ENC CONF
Change in rotation of direction allowed below 4880 Hz.
Change in rotation of direction allowed below 2440 Hz.
Change in rotation of direction allowed below 1220 Hz.
Change in rotation of direction allowed at any pulse frequency.
Pulse frequency of the channel(s)
< 2442 Hz
2442...4884 Hz
> 4884 Hz
