9.7.2.2 ENABLE input
The output stage of the servo amplifier is enabled by applying the ENABLE signal
(terminal X3/12, 24V input, active high).
In the disabled state (low signal) the connected motor has no torque.
9.7.2.3 AS-ENABLE input
An additional digital input (AS-Enable) releases the power output stage of the amplifier as long
as a 24V signal is applied to this input. If the AS-Enable input goes open-circuit, then power will
no longer be supplied to the motor, the drive will lose all torque and coast down to a stop. A fail-
safe brake function for the drive, if one is required, must be ensured through a mechanical
brake since electrical braking with the aid of the drive is no longer possible.
You can thus achieve a restart lock-out for personnel safety by using the AS-enable input in
conjunction with an external safety circuit.
You can find further information and connection examples on page 85.
This input is not compatible with IEC 61131-2
9.7.2.4 Programmable digital inputs
You can use the DIGITAL-IN1 to DIGITAL-IN4 digital inputs to initiate pre-programmed
functions that are stored in the servo amplifier.
A list of these pre-programmed functions can be found on the "Digital I/O" screen page of our
setup software PDrive.
If an input was freshly assigned to a pre-programmed function, then the data set must be saved
in the EEPROM of the servo amplifier and a reset has to be carried out (with the amplifier setup
software PDrive for example).
Note for a PMCprimo Drive3:
The digitale inputs DIGITAL-IN1 to DIGITAL-IN4 are denoted as E2:1 to E2:4 on a
PMCprimo Drive3.
