2.6.2. Infeed module interface
General
The pulse enable and drive enable interface is available in infeed module.
2.6.2.1. Grounding of electronics power supply - X131
General
It is the reference potential terminal for electronics power supply. This
terminal (screw M4) should be connected with the protective conductor in
NC using a cable with cross-section 4mm
2
.
2.6.2.2. Enable interface terminals - X141A
General
Terminal 63 is used for pulse enable input. Terminal 64 is for drive
enable input. They can be short-circuited with terminal 9, or controlled by
PLC.
Terminal 63 has the highest priority for enabling the pulses for all of the
modules and acts instantaneously.
Terminal 64 acts instantaneously on all modules. When the signal is
withdrawn, n
set
is set to 0 for all drives, and all of the controllers and
pulses are inhibited after a selected time has expired (setting when
supplied: 240 ms). The drive is braked along the current limit.
