Parameter Descriptions
ENCODER TYPE PREF: 71.04 Default: 3 Range: See below
This parameter defines the type of encoder being used.
Enumerated Value : Type
0 : QUADRATURE single-ended pulse encoder
1 : CLOCK/DIR single-ended pulse encoder
2 : CLOCK single-ended pulse encoder
3 : QUADRATURE DIFF differential pulse encoder
4 : CLOCK/DIR DIFF differential pulse encoder
5 : CLOCK DIFF differential pulse encoder
6 : SINCOS INC sin/cos encoder
7 : ABS ENDAT ST single turn endat absolute encoder
8 : ABS ENDAT MT multi-turn endat absolute encoder
Note that if an absolute endat encoder is used, the encoder MUST be wired exactly as specified. If not, it will fail to calibrate the absolute position
and an error will result when the drive is started. Its status can be viewed via the parameter CALIBRATN STATUS.
ENCODER MECH O/S PREF: 71.06 Default: 0.0000 deg Range: 0.0000 to
360.0000 deg
(Encoder mechanical offset). When using an absolute encoder, the SHAFT POSITION diagnostic shows the absolute position of the motor shaft.
The zero position can be adjusted by setting ENCODER MECH O/S. Rotate the motor shaft to the position which is required to be zero, and note
the value of SHAFT POSITION. Enter this value into ENCODER MECH O/S to zero its position.
ENCODER FBK %
PREF: 71.08 Default: —.xx % Range: —.xx %
This parameter shows the mechanical speed of the motor shaft, calculated from the encoder feedback, as a percentage of the user maximum speed
setting (MAX SPEED in the REFERENCE function block).
SHAFT POSITION PREF: 71.09 Default: —.xx deg Range: —.xx deg
This diagnostic provides the motor shaft position (before the gear box).
LOAD POSITION PREF: 71.10 Default: —.xx deg Range: —.xx deg
This diagnostic provides the motor load position (after the gear box).
