H70: Frequency Reference for Accel/Decel
Range: 0 - 1 (Default:0)
Description: This is the reference frequency for acceleration and deceleration. If a
decided accel/decel time from a frequency to a target frequency is required,
set this value to ‘Delta freq’. For most applications, the Max. freq. setting is
appropriate.
Accel/Decel time setting based on Operating Frequency:
•
Accel/Decel time is set at the ACC/dEC.
•
If you set H70 to 1 {Delta frequency}, Accel/Decel time is the time that it
takes to reach a target frequency from a steady state frequency.
