28 YASKAWA ELECTRIC TOEP C710616 50B YASKAWA AC Drive - A1000 6-Phase/12-Pulse Input Installation Guide
3.1 Standard Connection Diagram
3.1 Standard Connection Diagram
Connect the drive and peripheral devices as shown in Figure 3.1. It is possible to set and run the drive via the digital
operator without connecting digital I/O wiring. Refer to A1000 Quick Start Guide for instructions on operating the drive.
WARNING! Fire Hazard - Drive Short-Circuit Current Rating. Install adequate branch circuit protection according to applicable local
codes and this manual. Failure to comply could result in fire and damage to the A1000 drive or injury to personnel. The device is
suitable for use on a circuit capable of delivering not more than 100,000 RMS symmetrical amperes, 480 Vac maximum (400 V class),
when protected by branch circuit protection devices specified in this manual.
NOTICE: Equipment Hazard. Standard motors used with PWM drives may experience winding failures due to surge voltages, when
input line voltage is greater than 480 V or motor wire distance is greater than 100 meters. Select a motor design with insulation tolerant
of surge voltages, such as drive-rated motor for use with PWM drives. Failure to comply could lead to motor winding failure.
Note: The minimum load for the relay outputs M1-M2, M3-M4, M5-M6, and MA-MB-MC is 10 mA.
