[DI1] to [DI7].
2-step Acceleration/Deceleration Switching Condition Selection
(E125/E126 = “0: Switching by 2CH terminal (159: 2-step Accelera-
tion/Deceleration)” (Example 1)
• When 2CH terminal is ON, acceleration/deceleration is performed at acceleration time 2 (E12/E14)
or deceleration time 2 (E13/E15). When the terminal is OFF, acceleration/deceleration is performed
at acceleration time 1 (F07/E10) or deceleration time 1 (F08/E11).

• During forward rotation, acceleration is performed at acceleration time 1 (F07/E10) from output fre-
quency 0 Hz up to 2-step Acceleration Switching Frequency (E127/E129). Acceleration is performed
at acceleration time 2 (E12/E14) from 2-step Acceleration Switching Frequency (E127/E129) up to
the maximum output frequency.
• During reverse rotation, deceleration is performed at deceleration time 1 (F08/E11) from output fre-
quency 0 Hz up to 2-step Deceleration Switching Frequency (E129/E130). Deceleration is
