Pulse Count
Pulses:
The pulse count is the number of pulses per motor revolution
received from the encoder.
Scale
Depending on the encoder resolution and where it is mounted
(either directly on the motor or after gear reduction) scaling of
the position may be necessary.
The scale factor is used to convert or scale the encoder’s native
resolution into the controller’s internal door position value.
Internally the controller represents the door’s position as a
number in the range of +/- 32767. An optimal Pulse Count
setting of 32 is desired.
Since the controller is optimized for a Pulse Count setting of 32.
Divide the encoder’s native resolution by
Pulse Output
A BTR encoder specific menu to set the number of pulses per
revolution which is used in closed loop feedback.
It is unlikely that a user will need to change this parameter as it
is automatically computed when the
Gear Ratio Parameter is
set in the Motor Configuration submenu.
