F-2 Encoder Usage and Position StepLogic Application
Wiring Notes
The encoder can supply 5V or 12V power (250 mA maximum) for an
encoder. Be sure the DIP switch is set properly for the encoder. In
general, 12V will provide higher noise immunity.
The pulse-train/encoder inputs can handle 5V, 12V, or 24V inputs. The
inputs will automatically adjust to the voltage applied and no additional
drive adjustment is necessary. If a pulse-train or single-channel input is
used, it must be wired between the A (signal) and A- (signal common)
channels.
Important: A quadrature encoder provides rotor speed and direction.
Therefore, the encoder must be wired such that the forward
direction matches the motor forward direction. If the drive
is reading encoder speed but the position regulator or other
encoder function is not working properly, remove power to
the drive and swap the A and A (NOT) encoder channels or
swap any two motor leads.Drives using FRN 2.xx and
greater will fault when an encoder is incorrectly wired and
E216 [Motor Fdbk Type] is set to option 5 “Quad Check”.
Positioning Overview
The PowerFlex 40P includes a simple position regulator which can be
used in a variety of position applications without the need for multiple
limit switches or photo-eyes. This can be used as a stand-alone controller
for simple applications (up to 8 positions) or in conjunction with a
controller for more flexibility.
Please note that this is not intended to replace high end servo controllers
or any application that needs high bandwidth or very high torque at low
speeds.
