maximum output frequency will not be larger than 60 Hz even executing slip compensation. If
the output frequency must be larger than 60 Hz, adjust the output frequency upper limit or
increase the maximum operation frequency.

0: Unit 0.1 sec.
1: Unit 0.01 sec.
 The acceleration time determines the time required for the AC motor drive to ramp from 0.00 Hz
to the maximum operation frequency (Pr.01.00). The deceleration time determines the time
required for the AC motor drive to decelerate from the maximum operation frequency (Pr.01.00)
down to 0 Hz.
 Select the Acceleration/Deceleration Time 1, 2, 3, 4 with the multi-function input terminal
settings. The defaults are Acceleration Time 1 and Deceleration Time 1.
 The setting for Pr.01.19 changes the time unit of Pr.01.09–Pr.01.12, Pr.01.13, and Pr.01.14,
further changing the setting range of the acceleration / deceleration time.
