7.4 Setting up a feedback device
7.4.1 P1 position interface
This section shows the parameter settings which must be made to use each of the compatible feedback device types with P1 position interface on the
drive. For more information on the parameters listed here please refer to the Parameter Reference Guide.
Table 7-3 Parameters required for feedback device set-up on the P1 position interface
 Information required to be entered by the user.
Parameter can be set-up automatically by the drive through auto-configuration parameter. Must be set by the user if auto-configuration is disabled
(i.e. Pr 03.041 = Disabled (0)).
* Pr 03.036: If the output voltage from the encoder is >5 V, then termination resistors must be disabled by setting Pr 03.039 to 0.
Table 7-3 shows a summary of the parameters required to set-up each feedback device. More detailed information follows.
Autotune
(continued)
To perform an autotune:
•Set Pr 00.040 = 1 for a stationary autotune, Pr 00.040 = 2 for a rotating autotune.
• Close the run signal (terminal 7 or 8).
• Close the drive enable signal (terminals 11 and 13). The upper row of the display will flash ’Auto Tune’ while the
drive is performing the test.
• Wait for the drive to display 'Ready' or 'Inhibit' and for the motor to come to a standstill.
If the drive trips it cannot be reset until the drive enable signal (terminals 11 and 13) has been removed. See Chapter
13 Diagnostics on page 247.
• Remove the drive enabled and run signal from the drive.
Save
parameters
Select 'Save Parameters' in Pr mm.000 (alternatively enter a value of 1000 in Pr mm.000 ) and press red reset
button or toggle the reset digital input.
