32.1.2. CHECKING THE ENCODER OPERATION
Set I073 as Encoder Tune to check the correct operation of the incremental encoder selected as a speed feedback (see
the ENCODER/FREQUENCY INPUTS MENU) and to automatically set the correct direction of rotation.
NOTE
Before checking the correct operation of the encoder used as a speed feedback, enter the
motor ratings and the encoder ratings.
Please refer to the MOTOR CONFIGURATION MENU and the ENCODER/FREQUENCY
Once I073 is set as Encoder Tune and the ENABLE-A and ENABLE-B terminals have been closed, the connected
motor attains a speed of rotation of approx. 150 rpm; its speed of rotation is detected by the encoder, then the drive is
disabled. The following messages can be displayed on the display/keypad:
A059 Encoder Fault
W31 Encoder OK
Then the following message is always displayed:
W32 OPEN ENABLE
If alarm A059 Encoder Fault trips: in the encoder input, the value measured by the drive does not match with the real
speed of rotation of the motor. Check that the encoder is properly set up (see the ENCODER/FREQUENCY INPUTS
MENU) and wired; if the Encoder B input is used, check the Configuration of the dip–switches located on ES836 or
ES913 optional board (see the Sinus Penta’s Motor Drives Accessories – User Manual).
If W31 Encoder OK appears: the speed feedback from encoder is correct.
In addition, the autotune sets the encoder signal as feedback with parameter C199.
