STP-10 Hardware Manual

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 congured 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 congured 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.
