9. (F) Settings for Acceleration/Deceleration
9.3 Remote setting function
 Acceleration/deceleration operation
• The output frequency changes as follows when the set frequency is changed by the remote setting function.
NOTE
• If the time setting of the output frequency is longer than the time setting of the set frequency, the motor accelerates/decelerates
according to the time setting of the output frequency.
• Deceleration to the main speed or lower
By setting Pr.59 = "11 to 13", the speed can be decelerated to the frequency lower than the main speed (set by the External
operation frequency (except multi-speed setting) or PU operation frequency).
• Regardless of whether the remote setting is enabled or disabled, the acceleration/deceleration time set for the output
frequency can be changed to the second acceleration/deceleration time by turning ON the RT signal.
• The acceleration/deceleration time setting of the set frequency is fixed at the Pr.44 / Pr.45 setting.

Frequency setting storage
• The remotely set frequency is stored, held, or cleared according to the Pr.59 setting. When the inverter is turned ON again
and the operation is resumed, the setting shown in the parentheses will be applied.
• Storage conditions
The remotely-set frequency is stored at the point when the start signal (STF or STR) turns OFF. The remotely-set
frequency is stored every minute after turning OFF (ON) the RH and RM signals together. Every minute, the frequency is
overwritten in the EEPROM if the latest frequency is different from the previous one when comparing the two. This cannot
be written using the RL signal.
Frequency Time setting Description
Set frequency Pr.44 / Pr.45 The set frequency increases/decreases by remote setting according to the Pr.44 / Pr.45 setting.
Output frequency Pr.7 / Pr.8 The output frequency increases/decreases by the set frequency according to the Pr.7 / Pr.8 setting.
