16.5 SF-PR slip amount adjustment mode
16.5
SF-PR slip amount adjustment mode
• As compared to our conventional SF-JR motor, the slip amount is small for the high-performance energy-saving SF-PR
motor. When replacing the SF-JR to the SF-PR, the slip amount is reduced and the rotations per minute increases.
Therefore, when the SF-PR is used with the same frequency setting as that of the SF-JR, power consumption may
increase as compared to the SF-JR.
• By setting the slip amount adjustment mode, the frequency command can be adjusted to keep the rotations per minute of
the SF-PR equivalent to those of the SF-JR for power consumption reduction.
*1
The setting is available only for the 200/400 V class.
• By setting the number of SF-PR motor poles in
Pr.673 SF-PR slip amount adjustment operation selection
, the SF-PR
slip amount adjustment mode is activated.
• The SF-PR slip amount adjustment mode is available only under V/F control.
• Use
Pr.674 SF-PR slip amount adjustment gain
to fine-tune the rotations per minute. To reduce the rotations per minute
(to increase the compensation frequency), set a larger value in
Pr.674
. To increase the rotations per minute (to reduce the
compensation frequency), set a smaller value in
Pr.674
. (Lower rotations per minute reduce the power consumption, and
higher rotations per minute increase the power consumption.)
NOTE
• The slip amount adjustment is not available in the following conditions.
During acceleration/deceleration, during DC injection brake operation, during PID control, during stall prevention operation,
during regeneration avoidance operation, during traverse operation, and while the slip compensation is valid (
Pr.245
).
• The slip amount adjustment is not available when the applicable motor capacity of the inverter is not compatible with the SF-
PR. (For the details of the applicable motor capacity, refer to the Instruction Manual (Connection).)
