Power supply 3-phase, 380V to 480V–15% +10%
Note 1)
Shielding the circuit is recommended for the purpose of noise reduction.
Note 2)
Magnetic contactor MC2 must be the same rating as the contactor MC1 in the main circuit.
Note 3)
Servo may be turned on in the external sequence if the contact deposits: to protect the system,
provide the auxiliary contact.
Note 4)
Use 4.8 ї, 400 W resistor (to be supplied by customer).
Note 5)
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 6)
Provide an external protective device (e.g. thermal fuse) to monitor the temperature of the external
dynamic brake resistor.
