Connecting Input Signals
The STP 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 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 inputs can also be
connected to sensors, switches and other devices for use with Q 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.

High Speed Digital Inputs
The STP Series drives include two high speed inputs called STEP and DIR. They accept 5 volt single-ended or differential signals,
up to 2 MHz. Normally these inputs connect to an external controller that provides step & direction command signals. You can
also connect a master encoder to the high speed inputs for following applications. Or you can use these inputs with Wait Input, If
Input, Feed to Sensor, Seek Home and other such commands.
