Precautions of using 4-20mA input signal
VFAS1/PS1 have adopted the semiconductor switch as the change function of 4-20mA current input
and the voltage input of 0-10V.
When the power supply is turned off, 4-20mA input circuit will be in open state, then it will be in high
impedance condition.
Therefore if the 4-20mA current generator has a wire breakage detection, it will make the wire breakage
error.
When the power supply is turned on, the semiconductor switch will change in close state.
If the response of the 4-20mA current generator is not fast (0.2s or less), VFAS1/PS1 will detect over
voltage and occur trip E-10, analog input terminal over-voltage .
Caution
Mandatory
If you use 4-20mA current input for frequency setting, please perform the following
countermeasure.
(1) When the power supply turns on/off, please turn on/off also 4-20mA current signal.
(2) Please keep a control power to VFAS1/PS1 connecting the control power supply
backup option, CPS002Z, or external power supply of 24Vdc-1.05A.
Connect the control power supply device between control terminal +SU and CC.
(3)Between VI/II and CCA of control terminals, connect the resistor of 1/2W-500ohm or
470ohms, and use VI/II terminal not as 4-20mA input but as 0-10V input.
Therefore, please set the following parameter.
F108(analog VI/II voltage/current switching) =0 (voltage input:default setting)
F201(VI/II input point 1 setting) =20% (in case of 500 ohm)
19% (in case of 470 ohm)
F203(VI/II input point 2 setting) =98% (in case of 500 ohm)
93% (in case of 470 ohm)

QOperations
Danger Reference
Prohibited
• Do not touch inverter terminals when electrical power is applied to the inverter even if the
motor is stopped.
Touching the inverter terminals while power is connected to it may result in electric shock.
• Do not touch switches when thands are wet and do not try to clean the inverter with a damp
cloth.
Such practices may result in electric shock.
• Do not go near the motor in alarm-stop status when the retry function is selected.
The motor may suddenly restart and that could result in injury.
Take measures for safety, e.g. attaching a cover to the motor, against accidents when the
motor unexpectedly restarts.
• The inverter is tuned automatically (auto-tuning =, ) when the inverter is started
for the first time after setup.
During auto-tuning, which takes several seconds, the motor is energized, although it is
standing still. Noise may be produced by the motor during auto-tuning, which, however,
does not indicate that something is wrong with the inverter or the motor.
• Do not set the stall prevention level () extremely low.
If the stall prevention level parameter () is set at or below the no-load current of the
motor, the stall preventive function will always be active and increase the frequency when it
judges that regenerative braking is taking place.
Do not set the stall prevention level parameter () below 30% under normal use
conditions.
