Motor Rotation Direction Change - Omron VARISPEED L7 Manual

Motor Rated Power (E5-02)
Set E5-02 to the rated power value as written on the motor nameplate or in the motor data sheet.
Motor Rated Current (E5-03)
Set E5-03 to the motor rated current as written on the motor nameplate or in the motor data sheet.
Number of Motor Poles Setting (E5-04)
Set the number of motor poles as written on the motor nameplate or in the motor data sheet.
Motor Line-to-Line Resistance Setting (E5-05)
Set the motor line-to-line resistance as written in the motor data sheet. Alternatively a measured value can be
entered.
Motor d- and q-Axis Inductance (E5-06, E5-07)
Set the q-axis and d-axis inductance value in mH as written on the nameplate or the motor data sheet.
Motor Voltage Constant (E5-09)
Set the motor voltage constant k

Motor Rotation Direction Change

If the motor operates in the wrong direction with an Up or Down command, the direction can be changed by
parameter S3-08.

No.
F1-05 Encoder direction change
S3-08 Output phase order
Change Motor Direction in V/f or Open Loop Vector Control
To change the motor rotation direction without changing the wiring, parameter S3-08 can be changed.
If S3-08 = 0 the output phase order will be U-V-W
•
If S3-08 = 1 the output phase order will be U-W-V
•
Change Motor Direction in Closed Loop Vector Control
If Closed Loop Vector Control for IM or PM is used, besides changing parameter S3-08 the encoder direction
has to be changed by setting F1-05.
If Closed Loop Vector Control for PM motors is used, always perform an encoder offset tuning
after parameter S3-08 of F1-05 has been changed.
IMPORTANT
is set in mV as written on the nameplate or the motor data sheet.
