ABB ACS860 - Encoder 1 Configuration

Parameters 285
92
92 Encoder 1
configuration
Settings for encoder 1.
Notes:
• The contents of the parameter group vary according to the
selected encoder type.
92.01 Encoder 1 type Selects the type of encoder/resolver 1. None
configured
None configured None. 0
TTL TTL. Module type (input): FEN-01 (X31). 1
TTL+ TTL+. Module type (input): FEN-01 (X32). 2
HTL HTL. Module type (input): FEN-31 (X82). 5
92.02 Encoder 1 source Selects the interface module that the encoder is connected to.
(The physical locations and types of encoder interface
modules are defined in parameter group 91 Encoder module
settings.)
Module 1
Module 1 Interface module 1. 0
92.10 Pulses/revolution (Visible when a TTL, TTL+ or HTL encoder is selected)
Defines the pulse number per revolution.
2048
0…65535 Number of pulses. -
92.11 Pulse encoder type (Visible when a TTL, TTL+ or HTL encoder is selected)
Selects the type of encoder.
Quadrature
Quadrature Quadrature encoder (with two channels, A and B) 0
Single track Single-track encoder (with one channel, A).
Note: With this setting, the measured speed value is always
positive regardless of direction of rotation.
1
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:
