Kollmorgen SERVOSTAR 400 Assembly & Installation

4.7.2 Digital control inputs (X3)
All digital inputs are electrically isolated through optocouplers.
Technical data
— Reference ground is digital-GND (DGND, terminal X1/4,5 on the master)
— The logic is dimensioned for +24V / 7mA (PLC-compatible)
— H-level from +12...36V / 7mA, L-level from 0...7V/0mA
You can use the digital inputs PSTOP / NSTOP / DIGITAL-IN1 and DIGITAL-IN2 to
initiate pre-programmed functions that are stored in the servo amplifier.
You will find a list of the pre-programmed functions in the Online Help.
If an input has to be re-assigned to a pre-programmed function, then the data set must be
stored in the EEPROM of the servo amplifier, and the 24V auxiliary supply for the servo
amplifier must be switched off and then on again (to reset the amplifier software).
Limit-switches PSTOP / NSTOP
Terminals X3/6 and X3/7 are used to connect limit switches. They are deactivated upon
delivery. If these inputs are not needed for the connection of limit switches, then they can
be used for other input functions.
Limit-switch positive/negative (PSTOP / NSTOP, terminals X3/6 and X3/7), high level in
normal operation (fail-safe for cable break). A low signal (open) inhibits the corresponding
direction of rotation.
DIGITAL-IN 1 / DIGITAL-IN 2
You can link the digital inputs at terminals X3/4 (DIGITAL-IN 1) and X3/5 (DIGITAL-IN2)
with a pre-programmed function.
