3.3.2.2 Direction End Limit Signal (PEL / MEL)
The end-limit switches are usually installed on both ends of an
axis. The positive EL must be installed at the positive position of
the axis, and vice versa. If they are installed reversely, the protec-
tion will be invalid. These two signals are for safety, which can pre-
vent a machine crash when missing an operation.
The AMP-104C provides two direction end limit signals, PEL and
MEL, for each axis. PEL indicates the end limit signal is in the pos-
itive direction and MEL indicates the end limit signal is in the nega-
tive direction.
The external limit switch should have a contact capacity of +24V at
10mA minimum. The EL logical can be configured via switch.
