■ Use Motor Selection to Switch Acceleration and Deceleration Times
When you set H1-xx = 16 [MFDI Function Selection = Motor 2 Selection] you can activate and deactivate the
input terminal to switch between motor 1 and motor 2.
The following table shows the possible acceleration and deceleration time combinations when you use the Motor
2 Selection function.

ON C1-03 C1-04 C1-07 C1-08
■ Use Output Frequency Level to Switch Acceleration and Deceleration Times
The drive can use output frequency to automatically switch between different acceleration and deceleration times.
The acceleration and deceleration times for the drive are switched automatically when output frequency reaches
the setting value set to C1-11 [Accel/Decel Time Switchover Freq]. Set C1-11 = 0.0 Hz to disable this function.
Note:
• Acceleration and deceleration times set to MFDIs have priority over the automatic switching by the frequency level set to C1-11. For
example, if the MFDI terminal set for Accel/Decel Time Selection 1 [H1-xx = 7] is ON, the drive will use only Accel/Decel Time 2 (or
Accel/Decel Time 4 for motor 2). If you use a frequency level set in C1-11, the drive will not automatically switch acceleration and
deceleration times.
• If Motor 2 Selection [H1-xx = 16] is activated, the drive will set the acceleration/deceleration time to C1-05 and C1-06 for motor 2
when the output frequency is more than the frequency level set in C1-11.

Note:
When C1-10 = 0 [Accel/Decel Time Setting Units = 0.01 s (0.00 to 600.00 s)], the setting range is 0.00 s to 600.00 s.
