Parameter Descriptions
ENCODER INVERT
PREF: 158.03 Default: FALSE Range: FALSE/TRUE
This parameter is used to switch the direction of the input encoder, forward or reverse.
ENCODER TYPE
PREF: 158.04 Default: 0 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. This status can be viewed via the parameter
CALIBRATN STATUS.
ENCODER MECH O/S
PREF: 158.06 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 input encoder. The zero position can be adjusted by setting ENCODER MECH O/S. Locate 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.
