7:High limit frequency arriving

When the drive’s output frequency reaches high limit frequency, the terminal outputs indication

signal.

8: Low limit frequency arriving

When the drive’s output frequency reaches low limit frequency, the terminal outputs indication signal.

9: Overload signal

When overload occurs, the terminal outputs indication signal.

10: Over current stall

When over current stall occurs in running state, terminal outputs indication signal.

11: Over voltage stall

When over voltage stall occurs in running state, the terminal outputs indication signal.

12: External stoppingcommand

During running process, when external fault signal is received by the digital input terminals, the drive reports

ER11 fault, and the terminal outputs indication signal at the same time.

13: Preset counting value arriving

Set up counting value of the drive’s internal counter. The drive inputs counting pulses via external

terminals DIi (I=1~5),and the drive’s internal counter counts this signal. When the preset value

arrives, Yi outputs an indication signal. Whenthe next external counting pulse signal arrives,Yi 's

output signal recovers, and the counter restarts to count again at the same time.

14: Specified counting value arriving

When DIi inputsexternal counting pulse signal and the countingvalue reaches specified value defined

by p6.17 (See Fig. 6-22), Y1 outputsan indication signal, Y1 does not recover until speicified value

arrives.

As shown in Fig. 6-22, if P6.16=5, P6.17=3, when DIiinputs the 3th pulse, Y1 outputs anindication

signal. When DIi inputs the 5th pulse, Y1 outputs specified value arriving signal. Y1 will recover when

the 6th pulse arrives.

15: Low voltage lockup signal

When DC busvoltage is lower than the low voltage limit, the panel LED displays “LU”, and the

terminal outputs indication signal at the same time.

16: Overload pre-alarm

According to PD.04~PD.06overload pre-alarm setup,when the output current is higher than thesetting value,

the terminal outputs indicationsignal.

17: Drive failure signal

When fault occurs, the terminal outputs indication signal

18: Zero speed running

When the drive’s running frequency is zero, the terminal outputs indication signal.

For example, in the following three conditionsthe terminals output indication signal:

FWD/REV dead time running period;

The phase when the setup frequency islower than the start frequency when theinverter starts

from zero frequency;

In Dec process output frequency is lowerthan initial frequency of DC injectionbraking.

250ms.

20: End signal of stage of program operation

In program operation mode, when a cycle is finished, the inverter outputs a pulse with width of

250ms.

P6.11 Frequency arriving width (FAR)

Setting range:0.0～10.00Hz

When output terminal function is selected as frequency arriving signal, this function is used to detect

output frequency range. When error between output frequency and setting value is less than FAR, the

terminal outputs indication signal, as shown in Fig.6-24.

Note:

If bit 0 is set to 0, it means positive logic, and 1 for negative logic. Factory setting of all terminals

are positive logic;

In positive logic mode, terminal DIi is enabled if it is connected to the common terminal, and

disabled if disconnected;

In negative logic mode, terminal DIi is disabled if it is connected to the common terminal, and

enabled if disconnected;

In positive logic mode, terminal Yi closes when its output signal is valid;

In negative logic mode, terminal Yi opens when its output signal is valid;

Only decimal number can be set to the drive (including display). When negative logic is selected,

conversion from binary code to Hex value isshown as below:

Setting value ==（2*Y1）⁷+（2*DI5）⁴+（2*DI4）³+（2*DI3）²+（2*DI2）¹+DI1

For example,

if DI5 and DI4 select negative logic and others are positive logic, then:

Setting value =（2*1）⁴+（2*1）³+（2*0）²+（2*0）¹+0=16+8=24

Pd Faults and protection parameters

Pd.00 Motor overloadprotection mode

Setting range：0，1，2

0: No protection

1: Common motor protection

Since cooling conditions of common motordeteriorates at low speed, please lower the motor’s

thermalprotection threshold at this time.

2: Variable frequency motor protection

Since the variable frequency motorapplies forced air-cooling, the protection parametersneedn't be

adjusted during low speed running.

Pd.01 Motor overloadprotection factor

Setting range：20.0%-150.0%

Heat dissipation becomes worse at low frequency, and high temperature will reduce service life of the

motor. Through setting threshold of the electronic thermal overload relay, overload current and current limit

will be proportionally adjusted.

When motor capacity is lower than that of the drive, this function is used provide overheat protection for

the motor.

When several motors are driven by the same variable speed drive, this function is disabled. When

display readings reaches 100%, overload protection will be trigged

Pd.02 Over voltage stall selection

Setting range：0,1

Over voltage stall selection

0: Disabled;

1:Enabled

In inverter's Dec process, the actual motorspeed may be higher than the outputsynchronized speed

of the inverter due to theload inertia. At this time, the motor will feed theenergy back to the inverter, resulting

in thevoltage rise on the inverter's DC bus. If nomeasures being taken, tripping will occur dueto over

voltage.

The overvoltage stall protection function is thatduring the Dec running, the inverter detects thebus

voltage and compares it with the stallovervoltage point defined by PD.03. If the busvoltage exceeds the stall

overvoltage point, theinverter will stop reducing its output frequency.When the detected bus voltage is lower

thanthe point, the Dec running will be restored, asshown in Fig.6-32.

Pd.08 Frequency decrease rate during

Setting range：0.00-99.99Hz/S

Pd.09 Action mode of auto current limiting

Setting range：0、1、2

Auto current limiting function is used to limit theload current under the preset current (PD.07) in real

timeto avoid trip due to over-current. This function isespecially useful for the applications of larger

loadinertia or sharp change of load.

PD.07 defines the threshold for current limiting. Itssetting is a percentage of drive’s rated current Ie. PD.08

defines the decreasing rate of outputfrequency when the drive is in auto currentlimiting status. If PD.08 is

set too small, overload fault may occur.If PD.08 is set too big, the drive may be in energygeneration status

for long time that may result inovervoltage protection.

The action mode of auto current limiting functionis decided by PD.09:

PD.09= 0: disabled;

PD.09= 1:auto current limiting is effective duringacceleration or deceleration but ineffective

atconstant speed;

PD.09= 2: auto current limiting is effective duringacceleration/deceleration and constant speed;

Pd.10 Auto reset

Setting range：0～5

0: disabled;

1~5: times of fault reset;

Pd.11 Auto reset interval

Setting range：2～20s

When fault occurs, the drive stops output. After the time defined by PD.11, the drive resets fault

automatically and continue running.

PD.10 defines the times of auto fault reset. If PD.10=0, auto reset function is disabled, and user can only

reset fault in manual mode.

Pd.12 Relay action in Auto reset

Setting range：0、1

This parameter determine the relay action in auto reset period of the inverter.

0：no action

Pd.13Act selection at undervoltage fault

Setting range：0、1、2

When undervoltage occurs during running, fault relay acts and fault code will be saved. When

undervoltage occurs during stop state, fault relay does not act, and fault code will not be saved.

When undervoltage occurs in running or stopping state, fault relay acts and fault code will be

saved.

Chapter 7 Fault diagnosis and troubleshooting

7.1 Fault query at fault

If control power supply is normal at fault, the drive will be in fault displaying status all the times.

At this time, user can enter parameter group PH to get related information about the failure, such as

output frequency, frequency setting, output current, rotating direction, operating condition, and the

3 latest faults, which is shown in the table below.
