3.3.4 X7/X8 Digital Input
The X7/X8 input are designed for low speed digital input operation between 5 and 24 volts
optically Isolated differential input. They are normally used for end of travel limit switches. The
diagrams below show how to connect the X7/X8 Inputs to various commonly used devices
3.3.5 AIN Input
The TSM23S/Q drives have an analog input (AIN) which can accept a signal range of 0 to 5 volts.
The drive can be configured to operate at a speed or position that is proportional to the analog
signal. Use the Step-Servo Quick Tuner software to set the signal range, offset, dead-band and
filter frequency. The TSM23S/Q provides a +5 volt/100mA limit voltage supply that can be used to
power external devices such as potentiometers. It is not the most accurate supply for reference,
for more precise readings use an external supply that can provide the desired accuracy.
