4.4 Start-Up Flowcharts112 YASKAWA ELECTRIC SIEP C710616 27G YASKAWA AC Drive A1000 Technical Manual Subchart A-3: Operation with Permanent Magnet MotorsFlowchart A-3 in Figure 4.11 describes the set-up procedure for running a PM motor in Open Loop Vector Control. PMmotors can be used for more energy-efficient operation in reduced or variable torque applications.Note: 1. Although the drive sets parameters for the PG encoder during Auto-Tuning, sometimes the direction of the motor and direction of thePG get reversed. Use parameter F1-05 to switch the direction of the PG so that it matches the motor direction.2. The Z pulse must be realigned if the PG encoder is replaced. Set T2-01 to 3 to recalibrate the drive for the new encoder.Figure 4.10Figure 4.11 Operation with Permanent Magnet Motors<1> A motor code can be entered as the parameter setting for E5-01 when using a YASKAWA PM motor (SMRA Series, SSR1 Series, and SST4Series). If using a motor from another manufacturer, enter FFFF.<2> Make sure the motor and load can run freely, i.e., if a brake is mounted, make sure it is released.<3> ASR Gain Tuning automatically performs Inertia Tuning and sets parameters related to Feed Forward and the KEB Ride-Thru function.<4> Set E5-01 to the motor code to eliminate the need to perform tuning.
