5.6: Amplifier Configuration 
5.6.1: Digital Inputs 
5.6.1.1  Click Input/Output to open the Input/Output screen. 
A typical Input/Output screen is shown below. (Features vary with amplifier model and configuration.) 
Lo/Hi: Indicates state of input.
Red: inhibited motion or active input, depending on input function. Grey: motion not inhibited. None: not configured.
Indicates input is used as a CAN address bit.Hold position setting
5.6.1.2  Enter the following options: 
Parameter Description 
Pull up +5 V  Pulls up the group of inputs up to internal +5 V. 
Pull down  Pulls the group of inputs down to internal signal ground. 
Debounce 
Time 
Sets the input debounce time (how long an input must remain stable at a new state before the 
amplifier recognizes the state). Increase to prevent undesired multiple triggering caused by switch 
bounce. Debounce time is ignored for digital command inputs such as PWM. 
Range: 0 to 10,000 mSec. See Debounce Time (p. 32).
IN1-IN12  Select the function for the input. See Digital Input Functions (p 86).
*Hold position 
when limit 
switch is 
active 
Available in position mode when one or more inputs are configured as a limit switch (NEG Limit-HI 
Inhibits, NEG Limit-LO Inhibits, POS Limit-HI Inhibits, or POS Limit-LO Inhibits). The *Hold position 
option prevents any motion while a limit switch is active. 
CAUTION: If the amplifier is switched back to current or velocity mode with this option selected, the 
limit switches will no longer function. 
The Restore Defaults button restores all inputs and outputs to factory defaults. The Close button 
closes the screen.
