Parker 590+ series - Encoder

Programming D-59
DC590+ Series DC Digital Drive
ENCODER
This block allows the Speed Feedback
to be measured using a quadrature
encoder when a Speed Feedback
Option is fitted - refer to Chapter 3:
Speed Feedback and Technology
Options.
The ENCODER 1 function block is associated with the speed feedback option.
The ENCODER 2 function block is associated with Digital Input 2 (terminal C7) and Digital Input 3 (terminal C8) where:
Digital Input 2 provides the clock.
Digital Input 3 is used as a direction input.

Range
ENCODER LINES 24, 1230 10 to 5000
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. The 5901 Microtach has 1000 lines per revolution as standard. Proprietary encoders of other specifications can be normalised by
setting this parameter as appropriate.
ENCODER SIGN 49, 1231 NEGATIVE / POSITIVE
Since the encoder feedback cannot be reversed electrically, the signal polarity can be reversed by the control software.
It is necessary to set up this parameter when in CLOSED-LOOP VEC mode, as the encoder direction must be correct for this mode to operate.
ENCODER RPM 22, 1232 0 to 6000
Motor top speed setting (100%) when using encoder feedback.
