* In the operator mode (1st digit of Sn-04 is 1), frequency reference 1 (An-01) is enabled.
When the multi-function analog input is selected by functions other than the frequency reference
(Sn-19=0), frequency reference 2 (An-02) becomes effective. When the multi-function analog
input is not used, set F to the set value.
• For multi-step speed operation with frequency reference by keypad, perform the
following setting:
1 Sn-04 = ×××1 An-01 becomes effective.
2 Sn-19 ≠ 00 An-02 becomes effective.
5 Accel/decel time select (select value = 07)
• Accel/decel time is switched when “closed”. Switching is permitted even during acceleration
or deceleration.
Open: The accel/decel time is set by Bn-01 and Bn-02.
Closed: The accel/decel time is set by Bn-03 and Bn-04.
6 External baseblock (set value = 08)
• Baseblock is performed when “closed”. External baseblock differs as follows depending on
the input status of the run command:
When an external baseblock signal is input during run,“Ext. Baseblock bb” blinks at the
digital operator and AC drive output is shut OFF. When the external baseblock signal disappears,
the AC drive restarts with the frequency reference at that time. The voltage returns to the set
value in the voltage recovery time. When a stop signal is input and an external baseblock signal
is input while the AC drive is decelerating, “Ext. Baseblock bb” blinks at the digital operator, the
AC drive output is shut OFF, and the output frequency is set to 0Hz.
