4.5.9. External driver control interface
Interface allows to control any external driver with a help of 3 standard signals: enable, direction, clock. This mode is convenient when
controller power capability is not enough but it is desirable to use its capabilities such as limit switches, revolution sensor, position
control, scripting language, multiaxis systems, joystick/button control, magnetic brake, etc. For example, for creation of multiaxis
system with one powerful lifting axis which is controlled by external controller and two less powerful horizontal axes, you can use XiLab
with 3-axis interface and its scripts and also synchronize the motion of all three axes. I.e. external driver replaces only power part of
the controller.
Clock signal defines the quantity of signals in the given Direction (logical one to the right, logical zero to the left). Displacement is a
minimum step in the current settings of step division. For step division 1/32 there will be 32 impulses per one step. Don’t forget to set
external driver in such a way that it would use the same step division.
WARNING. Clock signal frequency in the given controller is limited by 78 kHz. That's why to reach necessary speed
one might need to reduce step division. Foe example, if rotation speed of 4000 steps per seconds is needed it is
necessary to use 1/8 step division or less.

Connection diagram
WARNING. Outputs for external driver control are not sufficiently protected and can be damaged in case of incorrect
usage. Proper connection and necessary electric protections are a responsibility of an engineer who designs drivers'
connection system.
Controller board
For external driver connection three outputs in
are used.
WARNING. Pin 13 is the general purpose input/output (see
General purpose digital input-output 8SMC5
), but it loses
its functionality when external driver control is enabled.
Scheme of connection to the external driver for the controller board
One-axis and two-axis systems
system has the external driver interface. It outputs on the
.
WARNING. Pins 12 and 25 are general purpose inputs/outputs (see
General purpose digital input-output 8SMC5
),
but they loses functionality when external driver control is enabled.
