MRH function usage selection (d-27) to MRH lower limit speed (d-29):
By using the MRH function usage selection (d-27 = on), you can control acceleration/deceleration through
contacts (MRH mode). At this time, by setting the operation commanding place selection to terminal block
through the settings of the command input when coupled (b-09) and speed command input (b-10), you can
speed up/down through the multifunction input contact. For information on the multifunction input function,
refer to "6.4. Area c (Multifunction Input Related Setting Area)" in Chapter 6 and "7.4. Area c (Multifunction
Input Related Setting Area)" in Chapter 7.
When an UP command is input, the speed is accelerated toward the MRH upper limit speed (d-28). When a
DOWN command is input, the speed is decelerated toward the MRH lower limit speed (d-29). When both of
UP and DOWN commands are not input or are input, the speed at that time is kept. However, if the speed is
beyond the MRH upper limit speed (d-28) or below the MRH lower limit speed (d-29), it is
decelerated/accelerated to the MRH upper limit speed (d-28) or MRH lower limit speed (d-29) automatically.
By setting a negative value to the MRH lower limit speed (d-29), you can operate in the forward and reverse
rotation through contacts.
When the setting of the MRH rotation
lower limit speed is positive
When the setting of the MRH rotation
lower limit speed is negative
* When a signal of the multifunction input preset speed selection or the speed commanding terminal block selection is
input during MRH mode selection, the speed command of the multifunction input preset speed or the speed
commanding terminal block takes priority, respectively.
For information on selection of MRH mode through the multifunction input function, refer to "6.4. Area c (Multifunction
Input Related Setting Area)" in Chapter 6 and "7.4. Area c (Multifunction Input Related Setting Area)" in Chapter 7.
