Connecting Input Signals
The ST drives have three types of inputs:
• high speed digital inputs for step & direction commands or encoder following, 5 volt logic
• digital inputs for other signals, 12 - 24 volt logic
• analog inputs for analog speed and positioning modes
All drives include eight digital inputs and two analog inputs.
• CW & CCW Limit: can be used to inhibit motion in a given direction, forcing the motor and load to travel
within mechanical limits. Can be configured for active closed, active open or not used.
• IN1/STEP & IN2/DIR: digital signals for commanding position. Quadrature signals from encoders can
also be used. These inputs can also be connected to sensors, switches and other devices for use with Q and
Si™ commands such as
Wait Input, Seek Home, Feed to Sensor, If Input
and others.
• IN3,4,5,6: software programmable inputs can be used for motor enable, alarm reset or jogging. These in
-
puts can also be connected to sensors, switches and other devices for use with Q and Si™
Wait Input, Seek
Home, Feed to Sensor, If Input
and other commands.
• Analog In: analog velocity or position command signal. Can be configured for 0-10V, 0-5V, ±10V or ±5V,
with or without offset.
