In the table, the signals shown in fields (EMGin, EMG1, SDN, ENBin, ENB1) must always be
connected regardless of the required safety category. If these signals are not connected, the safety
functions will be compromised.
In the table, the signals shown in fields (EMG2, ENB2) must be connected to meet safety category 3
or above. They are designed to provide redundant safety circuits.
In the table, the signal shown in fields (DET) provides an input for detecting malfunction of the safety
circuit (mainly fused relay contacts). This signal is disabled when the controller is shipped. To enable the
DET input, set bits 8 to 11 of I/O parameter No. 24 to “1” (= change I/O parameter No. 24 from the default
setting of 10000 to 10100).
Be sure to use this signal if you want the X-SEL controller to detect fused contacts. If the safety circuit is
configured as a closed system to manage fused contacts and other problems independently, safety
category 4 can be met without connecting this signal to the controller.
x DET
DET (IN) and DET (+24V) are dry contact input terminals consisting of a photocoupler. By inputting
fused contact detection signals from the drive source cutoff safety circuit, the controller will be able to
detect problems in the external safety circuit. To use the DET terminal, change I/O parameter No. 24
from the default setting of 10000 to 10100 (by setting bits 8 to 11 of I/O parameter No. 24 to “1”).
x SDN
SDN (OUT+) and SDN (OUT-) are output contacts that remain open while the controller is prohibiting
the motor power supply from the external power source. This condition will occur immediately after the
controller power is turned on, when an error occurs in the equipment, or when a drive source cutoff
cancellation command is not received by the EMG or ENB line. Configure the circuit in such a way that
the drive source will never be turned on when these contacts are open.
When turning on the power, turn on the controller power first, confirm that the SDN contacts are closed,
and then turn on the drive power. (If the control power and drive power are turned on simultaneously,
“E6D: Drive-source cutoff relay error” will generate.
