• 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).
Forward rotation(STF)
Acceleration(RH)
Deceleration(RM)
• 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 or third acceleration/deceleration time by turning ON the RT or X9 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.

1, 11
2, 12
3, 13
• 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.
