ENABLE input
The output stage of the servo amplifier is activated by the enable signal
(terminal X3/15, input 24V, 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 24V auxiliary supply of the servo amplifier must be
switched 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 terminal X3/11 (DIGITAL-IN 1) or terminal X3/12 (DIGITAL-IN 2) can be logi-
cally combined in a pre-programmed function.
