. 0006:
(Toggle acceleration and deceleration time). This input selects the acceleration 1 / deceleration 1 /
S curve 1 or acceleration 2 / deceleration 2 / S curve 2.

0007 or 0025:
(External Emergency Stop Contact A or B).
When the external emergency stop contact is
closed, the inverter will decelerate to stop via the time set by A026 (Deceleration time 2) and the display
will flash E.S when the emergency stop signal is received regardless of the b003 (Stopping method)
setting. To restart the drive after the external emergency stop contact is opened, press the run key on the
keypad or toggle the run input contact. The inverter will restart from the start frequency. If the emergency
signal is cleared before the inverter stops completely, the inverter still carries out the emergency stop.
The multifunction output relays, A105 (Relay output 1) and/or A106 (Relay output 2), will activate with an
emergency stop if A105 and/or /A106 = 9: (Rapid stop mode). Contact A is normally open, and activates
emergency stop when energized. Contact B is normally closed and emergency stop activates when de-
energized.

0008 or 0026
: (Base Block Contact A or B) The inverter output voltage immediately goes to 0, and the motor
does a coast stop. Contact A is normally open and base block activates when energized. Contact B is
normally closed and base block activates when de- energized.
7.
0009:
(Speed Search Start) When starting, the inverter detects the present speed of the motor, then
accelerates from that speed to preset speed.
8
.
0010:
(Energy-saving operation) With Fans, Pumps, or other high inertial loads, starting torques are typically
higher while at set speed, the torque demand is less. Consequently the output voltage to is reduced to
save energy. When the input in ON the output voltage will gradually decline as set speed is reached.
When OFF, the output voltage will gradually increase to the original voltage.
Note: The acceleration and deceleration rate during the energy saving operation is the same as that of
Speed Search.
9.
0011:
(Control signal selection)
OFF: The setting of b000 (Run source) and b001 (MFIT) determines the operating mode.
ON: The keypad controls the operating mode.
Note: The toggling of 0011 is allowed while the drive is running, however when doing this, please use
caution around the operating equipment.
10.
0012:
(Communication signal selection)
OFF: RS485 communication, from a PC or PLC can control the inverter operation and allow
modification to the parameters. The keypad and external control terminals TM2 are not functional
in this mode. Furthermore, the keypad can only display the voltage, current and frequency and the
parameters are read - only. The Emergency top is still valid.
