16 JVL Industri Elektronik A/S - User Manual - Integrated Stepper Motors MIS23x, 34x, 43x
2.2 Inputs
2.2.1 Inputs
The Quickstep motors has 8 inputs/outputs (IO’s) that each can be set individually to in-
put, output or analogue input 0-5VDC via MacTalk or software commands. See Using
MacTalk, page 57, for setup.
This means for example that it is possible to have 4 inputs, 3 outputs and one analogue
input.
Please notice: The number of available IO terminals available may vary de-
pending at which motor type you are using. Please the chapter Connector over-
view for the MIS23x, page 33 or Connector overview for the MIS34x, page 35

2.2.2 General Input features
• Inputs are TTL to 28VDC compliant.
• Over-current protection and thermal shut-down.
•10 kOhm input resistance.
• No galvanic isolation.
• Zero search input can be selected to any input 1 to 8.
• Digital filter can be enabled for each input selectable from 0 to 100ms. If disabled, the
response time is 100µs.
• Analogue filter can be selected for all analogue inputs.
