This section provides notes on using Σ-Series products.
2.1.1 Notes on Use
NOTE Always note the following to ensure safe use.
Use 200VAC power supply
Be sure to use the correct type. Do not plug the
servomotor directly into the power frequency sup-
ply (Direct connection to the power frequency
supply will damage the servomotor.)
Always use the SGMj servomotor and SGDB SERVOPACK in pairs.
Check whether the combination of applicable mo-
tor series of SERVOPACK and of SGMj ( motor
series) is correct or not. Check the setting of pa-
rameter Cn-2A (motor selection) and always after
changing its combination. The motor may get
damaged if the combination is not correct.
Do not change wiring when power is ON.
Always turn the power OFF before connecting or
disconnecting a connector.
(Except for Digital Operator (Types: JUSP-
OP02A-1, JUSP-OP03A))
Note that residual voltage still remains in the SERVOPACK even after the power is
turned OFF.
Even after the power is turned OFF, residual elec-
tric charge still remains in the capacitor inside the
SERVOPACK. To prevent an electric shock, al-
ways wait for the CHARGE lamp to go OFF before
starting inspection (if necessary).
