SET::ENC Menu
ENC MODE
F
Set this parameter to the requirements for your encoder:
0 : QUADRATURE (using digital inputs 6 & 7,
ENCA and ENCB respectively)
1 : CLOCK/DIR (using digital inputs 6 & 7,
ENCA and ENCB respectively)
2 : CLOCK (using digital input 6, ENCA)
0= QUADRATURE
1= CLOCK/DIR
2= CLOCK
0
ENC RESET
F
When TRUE the POSITION and SPEED outputs are set (and held) at zero. 0=FALSE
1=TRUE
0
ENC INVERT
F
When TRUE, changes the sign of the measured speed and the direction
of the position count.
0=FALSE
1=TRUE
0
ENC LINES
F
The number of lines must be set to match the type of encoder being
used. Incorrect setting of this parameter will result in an erroneous speed
measurement.
100 to 10000
100
ENC SPEED SCALE
F
This parameter allows the output "speed" to be scaled to any value the
user requires. With a default value of 1.00, the output "speed" is
measured in revs per second. Changing the ENC SPEED SCALE value to
60.00 will provide an output in revs per minute.
To provide an output in percent of the motor maximum speed, where
maximum speed is the maximum speed your motor will run in rpm, the
ENC SPEED SCALE parameter should be set to the result of:
6000
maximum speed (rpm)
0.00 to 300.00
1.00
ENC SPEED
F
Speed feedback, in units defined by the ENC SPEED SCALE parameter.

.x

.x
ENC SOURCE
F
Allow choosing the feedback source (external encoder or internal
feedback from the motor control’s sensorless algorithm)
0= EXTERNAL
1= INTERNAL
0
ENC POS SCALE
F
Allow scaling the position and speed feedback (in user-defined units)
from the raw measure. Expressed in number of lines per unit.
1 to 30000
1
ENC MODULO
F
Allow limiting the actual position (POS UNITS) range. Expressed in user-
defined units.
0 to 30000
0
ENC SPEED UNITS
F
Speed feedback, in user-defined units (using POS SCALE).

ENC POS UNITS
F
Position feedback, in user-defined units (using POS SCALE).

ENC PRESET VALUE
F
Value, in user-defined units, used to preset the actual position (POS
UNITS) when RESET is TRUE
-32768 to 32768
