2.1.1 Notes on Use
NOTE Always note the following to ensure safe use.
Two types of supply voltage are available, 100 V and 200 V.
Both Σ-Series Servomotor and Servopack have
100 V and 200 V types. Be sure to use the correct
type.
Always use the SGM/SGMP Servomotor and DR2 Servopack in pairs.
The SGM/SGMP Servomotor cannot run without
the DR2 Servopack.
Do not plug the SGM Servomotor directly into the
commercial power supply. (Direct connection to
the commercial power supply will damage the
Servomotor.)
Do not change wiring when power is ON.
Always turn the power OFF before connecting or
disconnecting a connector.
(Except for Digital Operator (Type: JUSP-
OP02A-1))
Note that residual voltage still remains in the Servopack even after the power is
turned OFF.
Even after the power is turned OFF, residual volt-
age still remains in the capacitor inside the Servo-
pack. Before inspection is to be performed, make
sure if CHARGE lamp is extinguished.
