3.1.2. Single-Phase 0.8kW 200V Main Circuit Specifications
XtraDrive XD-08-MS has been changed from three-phase specifications to single-
phase. Main circuit connection terminals (L1, L2, L3) remained.
These devices have terminal B3 and internal regenerative resistor. Observe the
following points.
1. Connect main power supply shown below to L1 and L3 terminals. Power supply is
single-phase, 220 to 230 VAC +10% to –15%, 50/60Hz. If power supply of 187V
(-15% of 220V) or less is used, alarm A.41 indicating voltage shortage, may occur
when accelerating to max speed with max torque of motor.
2. Short-circuit B2 and B3 terminals using the internal regenerative resistor. If
capacity of the regenerative resistor is insufficient, remove the lead between B2
and B3 terminals and connect an external regenerative resistor unit to B1 and B2
terminals.
