ABB ACS880-04XT User Manual

Parameters 463
Module input 1 Input 1 is echoed by or emulated to the TTL output. 1
Module input 2 Input 2 is echoed by or emulated to the TTL output. 2
91.32 Module 1 emulation
pulses/rev
Defines the number of TTL pulses per revolution for encoder
emulation output of interface module 1.
0
0…65535 Number of TTL pulses for emulation. 1 = 1
91.33 Module 1 emulated
Z-pulse offset
With interface module 1, defines when zero pulses are
emulated in relation to zero position received from the
encoder.
For example, with a value of 0.50000, a zero pulse is
emulated whenever the encoder position passes 0.5
revolutions. With a value of 0.00000, a zero pulse is emulated
whenever the encoder position passes zero position.
0.00000
0.00000 … 1.00000
rev
Position of emulated zero pulses. 32767 =
1rev
91.41 Module 2 TTL
output source
Selects the encoder input on interface module 2 whose signal
is echoed by or emulated to the TTL output.
See also section Encoder support (page 86).
Not selected
Not selected TTL output not in use. 0
Module input 1 Input 1 is echoed by or emulated to the TTL output. 1
Module input 2 Input 2 is echoed by or emulated to the TTL output. 2
91.42 Module 2 emulation
pulses/rev
Defines the number of TTL pulses per revolution for encoder
emulation output of interface module 2.
0
0…65535 Number of TTL pulses for emulation. 1 = 1
91.43 Module 2 emulated
Z-pulse offset
With interface module 2, defines when zero pulses are
emulated in relation to zero position received from the
encoder.
For example, with a value of 0.50000, a zero pulse is
emulated whenever the encoder position passes 0.5
revolutions. With a value of 0.00000, a zero pulse is emulated
whenever the encoder position passes zero position.
0
0.00000 … 1.00000
rev
Position of emulated zero pulses. 32767 =
1rev
92
92 Encoder 1
configuration
Settings for encoder 1.
Notes:
• The contents of the parameter group vary according to the
selected encoder type.
• It is recommended that encoder connection 1 (this group)
is used whenever possible since the data received through
that interface is fresher than the data received through
connection 2 (group 93 Encoder 2 configuration).
92.01 Encoder 1 type Selects the type of encoder/resolver 1. None
