Chapter 4 Configuring the Ultra5000 Drive
The following parameters can be entered and edited in the Encoders window.
Parameter Description
Motor Encoder Interpolation: The amount of interpolation to be used with sine/cosine
encoders:
• 4
• x8
• x16
• x32
• x64
• x128
• x256
• x512
• x1024
For example, if a Stegmann encoder outputs 1024 cycles per
revolution and Encoder interpolation is set to x256, the drive will
use 262144 (1024 x 256) counts per revolution as the effective
feedback.
Motor Encoder
Polarity The Motor Encoder’s polarity:
• Positive – turning the motor in a clockwise direction (as
viewed from the shaft end) increases the feedback position
(in counts).
• Negative – turning the motor in a clockwise direction (as
viewed from the shaft end) decreases the feedback position
(in counts).
Filter The state of the motor encoder filter:
• Disabled
• Enabled
Note: The filter reduces the upper limit of the rate at which
feedback pulses are recognized. You man need to enable
feedback in a noisy environment, or when a long encoder cable
is used.
Fault Mode The state of fault checking for the motor encoder at powerup:
• Disabled
• Enabled
Master Encoder
Polarity The Master Encoder’s polarity:
• Positive – turning the motor in a clockwise direction (as
viewed from the shaft end) increases the feedback position
(in counts).
• Negative – turning the motor in a clockwise direction (as
viewed from the shaft end) decreases the feedback position
(in counts).
Filter The state of the master encoder filter:
• Disabled
• Enabled
Note: The filter reduces the upper limit of the rate at which
feedback pulses are recognized. You man need to enable
feedback in a noisy environment, or when a long encoder cable
is used.
Fault Mode The state of fault checking for the master encoder at powerup:
• Disabled
• Enabled
