ABB ACL30 User Manual

Parameters 279
93.04 ENC POS EST ENA
Selects whether position estimation is used with
encoder to increase position data resolution or not.
TRUE /
enum
FALSE Measured position (Resolution: 4 x pulses per
revolution for quadrature encoders, 2 x pulses per
revolution for single track encoders.)
0
TRUE Estimated position. (Uses position extrapolation.
Extrapolated at the time of data request.)
1
93.05 ENC SP EST ENA
Selects whether calculated or estimated speed is
used with encoder.
FALSE /
enum
FALSE Last calculated speed (calculation interval is 62.5
µs…4 ms).
0
TRUE Estimated speed (estimated at the time of data
request) Estimation increases the speed ripple in
steady state operation, but improves the dynamics.
1
93.06 ENC OSC LIM
Activates transient filter for encoder. Changes of
direction of rotation are ignored above the selected
pulse frequency.
4880Hz /
enum
4880Hz Change in rotation of direction allowed below
4880 Hz.
0
2440Hz Change in rotation of direction allowed below
2440 Hz.
1
1220Hz Change in rotation of direction allowed below
1220 Hz.
2
Disabled Change in rotation of direction allowed at any pulse
frequency.
3
93.07 EMUL PULSE NR
Defines the number of TTL pulses per revolution
used in encoder emulation.
Encoder emulation is enabled by parameter 90.02
EMUL MODE SEL.
0 / UINT32
0…65535
TTL pulses used in encoder emulation.
1 = 1 / -
93.08 EMUL POS REF
Selects the source for the position value used in
encoder emulation when parameter 90.02 EMUL
MODE SEL is set to FEN-01 SWref, FEN-11 SWref,
FEN-21 SWref or FEN-31 SWref. See parameter
group 90 ENC MODULE SEL.
The source can be any actual or reference position
value (except 01.09 ENCODER POS).
