PARAMETERS

Initial value for the FR-A860-01080 or lower.

Initial value for the FR-A860-01440 and higher.

110% for SLD, 120% for LD, 150% for ND, and 200% for HD (Refer to Pr.570 Multiple rating setting page 249 .)

The Pr.702 Maximum motor frequency is used as the maximum motor frequency. When Pr.702 =“9999 (initial value)", the Pr.84 Rated motor
frequency is used as the maximum motor frequency.
NOTE
• If PM parameter initialization is performed in rotations per minute (
Pr.998
= "8009 or 9009"), the parameters not listed in the table
and the monitored items are also set and displayed in rotations per minute.
