Power Supply and Stop Circuit / Drive Cutoff Circuit
The circuit related to RCON's drive-source cutoff is shown below. RCON gets the motor power
supplied from the gateway unit for the 24V system and from the 200V power supply unit for the
200V system, however, the circuit related to drive cutoff is on the driver unit side.
• A driver unit possesses a drive cutoff circuit by the semiconductor for each axis and an EC
connect unit for every four axes. Also, the motor power supply should be cut off by STOP
Signal. The drive source cutoff circuit via semiconductor has an overcurrent detection function
and an inrush current restriction function.
[For 24V System Driver Unit (RCON-PC/PCF/AC/DC)]
• Each driver unit has an interface (Drive-source cutoff connector: MPI/MPO) that can shut off
the external drive source of each axis.
[For 200V System Driver Unit (RCON-SC)]
• Each driver unit possesses a drive cutoff circuit and the driver stop circuit by the internal
semiconductor instead of an external drive cutoff connector.
• The driver stop circuit (DRV STOP) cuts off the energy supply to the motor by the cutoff circuit
in the controller after a reaction time (8ms or less) in response to the input signal.
[For EC Connection Unit (RCON-EC)]
• There are some interfaces (drive cutoff connectors: MPI/MPO) available which enables to cut
off drive externally for each axis of each EC connection unit.
