Chapter 6 - Parameter Description [I/O]
6-41
[XCEL stop]
Inverter stops accelerating and decelerating when this
terminal is ON.
[P Gain2]
This function is used to change P-Gain during PID
operation. When this terminal is ON, PID controller
changes P-Gain with PID P2-Gian set in FU2-59.
Refer to PID Control Block Diagram
.
[SEQ-L, SEQ-M, SEQ-H]
These functions are used for Auto drive (I/O-50).
Five different sequences can be selected according to the
combination of these terminals. Eight step frequencies,
Accel/Decel time and steady speed time can be set for
each sequence. The following table shows the sequence
of selection.

Note: The inverter stops after finishing all steps of that
sequence once the Auto (Sequence) operation is started.
To stop the inverter during sequence operation, use ‘BX’
terminal on the control terminal strip.
[Manual]
This is used to exchange the operation mode of inverter
from Auto (Sequence) to manual operation.
DRV-03 [Drive Mode] and DRV-04 [Frequency Mode] are
applied when the mode has been changed.
☞
Note: This function can be used only when the inverter is
stopped.
[Go step]
This is used to trigger the next step in a sequence of Auto-
B operation.
[Hold step]
This is used to hold the last step frequency in Auto-A
operation.
