7 External baseblock (set value = 09)
• Baseblock is active when “open”. All other operations are the same as when set value = 8.
8 Accel/decel speed prohibit command (set value = 0A)
• As long as the accel/decel speed prohibit command is asserted, accel/decel speed is prohibited
and the output frequency at that time is held. When a stop command is asserted, the accel/decel
speed prohibit state is released and the system enters a stopped state. The figure below shows a
time chart.
Note: If the run command is asserted again after the stop command, while the accel/decel prohibit
command is inputed, the holding output frequency is stored unless the accel/decel prohibit command
is released. Therefore, operation is performed at the stored output frequency. Also when the power
supply is turned OFF in the accel/decel prohibit command input status, the holding output frequency
is still stored.
9 AC drive overheat alarm (set value = 0B)
• As long as an AC drive overheat signal is asserted, the “Over Heat OH2” blinks at the
digital operator.
10 UP command/DOWN command (set value = 10, 11)
• Acceleration/deceleration is performed by inputting the UP/DOWN commands without
changing frequency reference in the forward (reverse) run command input status, and
operation can be performed at a desired speed.
Set value = 10: UP command
Set value = 11: DOWN command
