* 1. SGDH-08AE-S SERVOPACK (for SGMAH-08A, SGMPH-08A Servomotor) and SGDH-15AE-S
SERVOPACK (for SGMPH-15A Servomotor) have single-phase, 220 V power supply specifica-
tions. Connect the following power supply between L1 and L3.
Single-phase 220 to 230 VAC
+10%, -15%
(50/60 Hz)
If a power supply of 187 V (-15% of 220 V) or less is used, alarm 41, which indicates a voltage
shortage, may occur when accelerating to the maximum speed with the maximum torque of the
servomotor.
* 2. If using the main circuit power supply and the control power supply with DC power supply input,
refer to
6.1.3 Typical Main Circuit Wiring Examples (5) DC Power Supply Input
for more informa-
tion on wiring.
