4.3.2 Position Control - Digital
This mode is for systems where the position of the motor is determined by a digital input signal in
the form of pulses.
Digital Settings
Input Noise Filter
- The digital inputs used in this mode are very high speed and can be sensitive
to external electrical noise. The Input Noise Filter sets a hardware circuit to filter out unwanted
noise that can cause extra steps. As a general rule, the filter frequency should be set to double
that of the desired maximum input frequency. If the frequency is set too low it may cause loss of
step counts. When setting this value the performance over the whole range of desired speeds
should be considered.
Digital Signal Types -
There are three types available:
•
Pulse & Direction
- accepts signals such as those generated by a step motor controller. The
frequency of the pulses fed into X1/STEP determines the speed. The direction of rotation is
determined by the signal fed into X2/DIR - with either an ON or an OFF signal commanding
clockwise motion.
•
CW & CCW Pulse
- The motor will move CW or CCW depending on which input the pulse is
fed into. Either X1/STEP or X2/DIR can be used for CW rotation.
•
A/B Quadrature
- sometimes called “Slave Mode”. The motor will move according to signals
fed to the drive from a master encoder. This encoder can be mounted to a rotating mechanism
on a machine or it can be another motor in the system. Rotation direction is determined by
which input is “leading” the other.
