Mains power terminals (R/L1, S/L2, T/L3 and L/L1, N/L2)
Connect these terminals via a non-fuse breaker or earth leakage breaker to 3-phase AC
power (some models to 1-phase AC power) for circuit protection. It is unnecessary to
consider phase-sequence.
It is recommended to add a magnetic contactor (MC) in the power input wiring to cut off
power quickly and reduce malfunction when activating the protection function of AC
motor drives. Both ends of the MC should have an R-C surge absorber.
Do NOT run/stop AC motor drives by turning the power ON/OFF. Run/stop AC motor
drives by RUN/STOP command via control terminals or keypad. If you still need to
run/stop AC drives by turning power ON/OFF, it is recommended to do so only ONCE
per hour.
Do NOT connect 3-phase models to a 1-phase power source.
Control circuit terminals (U/T1, V/T2, W/T3)
When the AC drive output terminals U/T1, V/T2, and W/T3 are connected to the motor
terminals U/T1, V/T2, and W/T3, respectively, the motor will rotate counterclockwise (as
viewed on the shaft end of the motor) when a forward operation command is received.
To permanently reverse the direction of motor rotation, switch over any of the two motor
leads.

DO NOT connect phase-compensation capacitors or surge absorbers at the output
terminals of AC motor drives.
With long motor cables, high capacitive switching current peaks can cause over-current,
high leakage current or lower current readout accuracy. To prevent this, the motor cable
should be less than 20m for 3.7kW models and below. And the cable should be less than
50m for 5.5kW models and above. For longer motor cables use an AC output reactor.
Use a well-insulated motor, suitable for inverter operation.

decimal point; it separates ones and tenths as in “30.5” (thirty and one-half).
A single decimal point after the right-most numbers is not a true decimal point,
999.
instead it indicates that a zero follows the right-most number. For example, the
number 1230 would be displayed as “123.”
Two decimal points (one between the middle and the right-most numbers, and
one after the right-most number) are not true decimal points; instead they indicate
99.9.
that two zeros follow the right-most number. For example, the number 34500

2-02 Stop Method
Factory Setting: d0
Settings d0 STOP: ramp to stop E.F.: coast to stop
d1 STOP: coast to stop E.F.: coast to stop
The parameter determines how the motor is stopped when the AC motor drive receives a
valid stop command or detects External Fault.
Ramp: the AC motor drive decelerates to Minimum Output Frequency (Pr.1-05)
according to the deceleration time set in Pr.1-10 or Pr.1-12 and then stops.
Coast: the AC motor drive stops the output instantly upon command, and the motor
free runs until it comes to a complete standstill.
The motor stop method is usually determined by the characteristics of the motor load and
how frequently it is stopped.
(1) It is recommended to use “ramp to stop” for safety of personnel or to prevent
material from being wasted in applications where the motor has to stop after
the drive is stopped. The deceleration time has to be set accordingly.
(2) If motor free running is allowed or the load inertia is large, it is recommended to
select “coast to stop”. For example: blowers, punching machines, centrifuges
and pumps.

The analog output voltage is directly proportional to the output frequency of the AC drive. With
the factory setting of 100%, the Maximum Output Frequency (Pr.1-00) of the AC drive
corresponds to +10VDC analog voltage output. (The actual voltage is about +10VDC, and
can be adjusted by Pr.3-01).
The analog output voltage is directly proportional to the output current of the AC drive. With
the factory setting of 100%, the 2.5 times rated current of the AC drive corresponds to
+10VDC analog voltage output. (The actual voltage is about +10VDC, and can be adjusted by
Pr. 3-01)
NOTE
Voltmeter specification: The sourcing capability of the output is limited to 0.21mA. Sourcing voltage:
10V. Output resistance: 47kΩ.
If the meter reads full scale at a voltage less than 10 volts, then Pr.3-01 should be set by
the following formula: Pr.3-01 = ((meter full scale voltage)/10) ×100%
For example: When using the meter with full scale of 5 volts, adjust Pr.3-01 to 50%.

of pressure, temperature, or flow is needed. Under a high pressure or flow situation, a sensor will
generate a large signal such as 20 mA or 10V. With anti-slope enable, the large signal will slow or
stop the AC drive.

NOTE
When value d3 is selected for Pr. 4-04, this will over ride any value entered in Pr.4-05, since Pr.4-05
must be used for three wire control as shown above.
d4, d5 External Faults:
Parameter values d4, d5 programs Multi-Function Input Terminals: M1 (Pr. 4-04), M2 (Pr. 4-05), M3
(Pr. 4-06), M4 (Pr. 4-07) or M5 (Pr. 4-08) to be External Fault (E.F.) inputs.
NOTE
When an External Fault input signal is received, the AC drive will stop all output and display “ E.F.”
on Digital Keypad, the motor will free run. Normal operation can resume after the External Fault is
cleared and the AC drive is reset.
d6 External Reset:
Parameter value d6 programs a Multi-Function Input Terminal: M1 (Pr.4-04), M2 (Pr.4-05), M3 (Pr.4-
06), M4 (Pr.4-07) or M5 (Pr.4-08) to be an External Reset.

NOTE
the External Reset has the same function as the Reset key on the Digital keypad. After external fault
such as O.H., O.C. and O.V. are clear, this input can be used to reset the drive.
d7, d8, d9 Multi-Step Speed Command:
Parameter values d7, d8, d9 programs any three of the following Multi-Function Input Terminals: M1
(Pr.4-04), M2 (Pr.4-05), M3 (Pr.4-06), M4 (Pr.4-07) or M5 (Pr.4-08) for multi-step speed command
function.
