ENABLE input
The output stage of the servo amplifier is activated by the enable signal
(terminal X3/15, input 24 V, active-high).
In the inhibited state (low signal) the motor which is attached does not have any torque.
Programmable digital inputs :
You can use the digital inputs PSTOP / NSTOP / DIGITAL-IN1 and DIGITAL-IN2 to initiate
preprogrammed functions that are stored in the servo amplifier.
You can find a list of pre-programmed functions on the "digital I/O" screen of our setup software.
If an input is freshly assigned to a pre-programmed function, then the data set must be stored in the
EEPROM of the servo amplifier, and the 24 V auxiliary supply of the servo amplifier must be swit-
ched off and on again (to reset the amplifier software).
Limit-switches PSTOP / NSTOP
Terminals X3/13 and X3/14 are normally programmed for the connection of limit switches. If these
inputs are not needed for the connection of limit switches, then they are programmable for other
input functions.
Limit-switch positive/negative (PSTOP / NSTOP, terminals X3/13 and X3/14), high level in normal
operation (fail-safe for a cable break).
A low signal (open) inhibits the corresponding direction of rotation, the ramp function remains
effective.
DIGITAL-IN 1 / DIGITAL-IN 2
The digital inputs on terminals X3/11 (DIGITAL-IN 1) or terminal X3/12 (DIGITAL-IN 2) can be logi-
cally combined in a pre-programmable function.

Reference ground is Digital-GND (DGND, terminal X3/18)
Inputs at X3 meet PLC standards (IEC 61131-2 Typ 1)
High: 11...30 V / 2...11 mA, Low -3...+5 V / <1 mA
Update rate: 250 µs
