E1 Series Servo Drive User Manual Electrical Planning
5-16 HIWIN MIKROSYSTEM CORP.
While using single-phase AC 220 V as main circuit power supply, set Pt00B = t.1
(Three-phase/single-phase power input selection). For more information, please refer to section 6.3.1.
5.3.2 Wiring for main circuit connector
Wiring or examination must be performed by professional technician.
The power must be turned off before wiring or examination to avoid short circuit or electric shock.
The residual voltage inside the servo drive could still be high after power off. Wiring should be performed five
minutes after power off and the indicator goes off.
5.3.3 Power-on sequence
Pay attention to the following while designing power-on sequence.
(1) The control power supply must be turned on before the main circuit power supply. After 20 ms, the
servo drive outputs drive ready output (D-RDY) signal. Ensure the control power supply is turned on
prior to the main circuit power supply while designing power-on sequence. For information of D-RDY
signal, please refer to section 8.1.5.
