Preparation
Compose the circuit so that the main circuit power will be shut off when an error occurs.
In Case of 3-Phase, H-frame, 200 V type
Power supply 3-phase, 200V
MCCB

Note 2)
Dynamic Brake resistor
Note 3)
Note 1)
Magnetic contactor MC2 must be the same as the contactor MC1 in the main circuit.
Note 2)
Servo may be turned on in the external sequence if the dynamic brake resistor deposits: to protect the
system, provide the auxiliary contact.
Note 3)
Use 1.2 , 400 W resistor (to be supplied by customer).
Note 4)
To use the external dynamic brake resistor:
Connect the R1 and R2 terminals to B1 and B2.
Connect the T1 and T2 terminals as shown in the left diagram.
Connect the 24 V and 0 V terminals to a 24 VDC power supply.
Connect the E terminal to the ground.
Refer to P.7-122 "Options" for the specifications of the external regenerative resistor.
Note 5)
Provide an external protective device (e.g. thermal fuse) to monitor the temperature of the external
dynamic brake resistor.
Note The wiring indicated with the broken line shall be provided only when required.
