Subchart A-3: Operation with Permanent Magnet Motors

Flowchart A3 in

Figure 4.7

describes the setup procedure for running a PM motor in Open Loop Vector Control. PM motors

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 the

PG get reversed. Use parameter F1-05 to switch the direction of the PG so that it matches the motor direction.

2. Realign the Z Pulse if the PG encoder is replaced. Set T2-01 to 3 to recalibrate the drive for the new encoder.

Motor test report/ data

sheet available?

Input the motor data.

Should the drive set ASR gain

automatically?

Run the motor without load; check the rotation direction and
operation.Verify external signal commands to the drive work as desired.

Perform Back EMF Constant

Tuning (T2-01=11)

Figure 4.7 Operation with Permanent Magnet Motors

<1> Enter the motor code to E5-01 when using a Yaskawa PM motor (SMRA Series, SSR1 Series, and SST4 Series). 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> Back EMF Constant Tuning automatically measures motor induced voltage and then sets E5-09 when the motor report or data

sheets are not available.

<5> This type of Auto-Tuning is available in drive software versions PRG: 1015 and later.
