ABB ACS880-104

Parameters 465
92.12 Speed calculation
mode
(Visible when a TTL, TTL+ or HTL encoder is selected)
Selects the speed calculation mode.
*With a single-track encoder (parameter 92.11 Pulse encoder
type is set to Single track), the speed is always positive.
Auto rising
A&B all Channels A and B: Rising and falling edges are used for
speed calculation.
*Channel B: Defines the direction of rotation.
Note: With a single-track encoder (parameter 92.11 Pulse
encoder type), this setting acts like setting A all.
0
A all Channel A: Rising and falling edges are used for speed
calculation.
*Channel B: Defines the direction of rotation.
1
A rising Channel A: Rising edges are used for speed calculation.
*Channel B: Defines the direction of rotation.
2
A falling Channel A: Falling edges are used for speed calculation.
*Channel B: Defines the direction of rotation.
3
Auto rising One of the above modes is selected automatically depending
on the pulse frequency as follows:
4
Auto falling One of the above modes is selected automatically depending
on the pulse frequency as follows:
5
92.12 Zero pulse enable (Visible when an absolute encoder is selected)
Enables the encoder zero pulse for the absolute encoder
input (X42) of the FEN-11 interface module.
Note: No zero pulse exists with serial interfaces, ie. when
parameter 92.11 Absolute position source is set to EnDat,
Hiperface, SSI or Tamagawa.
Disable
Disable Zero pulse disabled. 0
Enable Zero pulse enabled. 1
92.12 Resolver polepairs (Visible when a resolver is selected)
Defines the number of pole pairs of the resolver.
1
1…32 Number of resolver pole pairs. 1 = 1
92.13 Position estimation
enable
(Visible when a TTL, TTL+ or HTL encoder is selected)
Selects whether position estimation is used with encoder 1 to
increase position data resolution or not.
Enable
Disable Measured position used. (The resolution is 4 × pulses per
revolution for quadrature encoders, 2 × pulses per revolution
for single-track encoders.)
