BTAC-02 pulse encoder interface module 165
Apply power
1. Turn on the input power to the drive.
2. Continue with Start-up on page 165 .
Start-up
To configure the operation of the BTAC module:
1. Power up the drive.
2. Set group 90 Feedback selection , 91 Encoder adapter settings and 92 These
parameters display the configuration of the encoder interface modules. Encoder
configuration
parameters described on pages 165 … 166 .

Feedback selection
Use these parameters to select feedback or display feedback from the encoder.
No. Name/Value Description Def/FbEq16/32
90 Feedback selection
90.01 Motor speed for
control Displays the estimated or measured motor speed that is
used for motor control, ie. final motor speed feedback
selected by parameter 90.41 Motor feedback selection
and filtered by 90.42 Motor speed filter time.
This parameter is read-only. -
-32768…32767 Motor speed used for control. 1=1 rpm/
100=1 rpm
90.02 Motor position Displays the motor position (within one revolution)
received from the source selected by parameter 90.41
Motor feedback selection.
0 … 1 rev Motor position. 32767=1 rev/
100000000=1
rev
90.10 Enc1 speed Displays encoder 1 speed in rpm.
This parameter is read-only. -
-32768…32767 Encoder 1 speed. 1=1 rpm/
100=1 rpm
90.11 Enc1 position Displays the actual position of encoder 1 within one
revolution.
This parameter is read-only. -
0 … 1 rev Encoder 1 position within one revolution. 32767=1 rev/
100000000=1
rev
90.13 Enc1 revol
extension Displays the revolution counter extension.
The counter is incremented when encoder position
wraps around in the positive direction, and decremented
in the negative direction.
The parameter is effective only if the position is
absolute.The parameter value is updated for both single-
turn and multiturn encoders.
This parameter is read-only. na/1=1
