1.2 Safety guidelines

| |

◊ Only trained and qualified professionals are allowed to carry out related operations.
◊ Do not perform wiring, inspection or component replacement when power supply is applied. Ensure all the input power supplies have been disconnected before wiring or inspection, and wait for at least the time designated on the VFD or until the DC bus voltage is less than 36V. The minimum waiting time is in the following.

---|---|---
VFD model| Minimum waiting time
1 PH 220V     2.2kW| 5 minutes
3PH 220V     2.2kW-4kW| 5 minutes
3PH 380V 4kW-7.5kW| 5 minutes
| + Do not refit the VFD unless authorized; otherwise fire, electric shock or other injury may result.
| +The base may become hot when the machine is running. Do not touch. Otherwise, you may get burnt.
| +The electrical parts and components inside the VFD are electrostatic sensitive.
Take measurements to prevent electrostatic discharge when performing related operations.

1.3 Environment condition

Ambient
temperature| ◊-10—+50°C
◊ When the ambient temperature exceeds 40°C, derate 1% for every increase of 1°C.
◊ Do not use the VFD when the ambient temperature exceeds 50°C.
◊ In order to improve reliability, do not use the VFD in the places where the temperature changes rapidly.
◊ When the VFD is used in a closed space, such as control cabinet, use a cooling fan or air conditioner for cooling, preventing the internal temperature from exceeding the temperature required.
◊ When the temperature is too low, if you want to use the VFD that has been idled for a long time, install an external heating device before the use to eliminate the freeze inside the VFD. Otherwise, the VFD may be damaged.
Relative humidity (RH)| ◊ RH: less than 90%
◊ Condensation is not allowed.
◊ The max. RH cannot exceed 60% in the environment where there are corrosive gases.
Running environment| Install the VFD in a place:
◊ Away from electromagnetic radiation sources
◊ Without oil mist, corrosive gas, flammable gas, radioactive gas, contaminative air, or contaminative liquid.
◊ Without the chance for foreign objects such as metal powder, dust, oil and water to fall into the VFD (do not install the VFD onto combustible objects such as wood)
◊ With low salt content
◊ Without direct sunlight.
Altitude| ◊ Lower than 1000 meters
◊ When the altitude exceeds 1000m, derate by 1% for every additional 100m. 4-When the installation site altitude exceeds 3000m, consult the local INVT dealer or office.
Vibration| The max. amplitude of vibration cannot exceed 5.8m/s2 (0.6g).
Installation direction| Install the VFD vertically to ensure good heat dissipation performance.

 Common function parameters

6 Common function parameters

The following table briefly describes some common function parameters and typical values.

“0” indicates that the value of the parameter can be modified when the VFD is in stopped or running state.

“©” indicates that the value of the parameter cannot be modified when the VFD is in running state.

“•” indicates that the value of the parameter is detected and recorded, and cannot be modified.

(The VFD automatically checks and constrains the modification of parameters, which helps prevent incorrect modifications.)

Function
code| Name| Description| Default| Modify
---|---|---|---|---
| | Advantage of high carrier frequency:  ideal current  waveform,little current harmonic wave and motor noise.
Disadvantage of  high carrier frequency: increasing the switch loss, increasing VFD temperature and the impact to the output capacity. The VFD needs to derate on high carrier frequency. At the same time, the leakage and electrical magnetic interference will increase.
On the contrary, an extremely-low carrier frequency may cause unstable operation at low frequency, decrease the torque, or even lead to oscillation.
The carrier frequency has been properly set in the factory before the VFD is delivered. In general, you do not need to modify it.
When the frequency used exceeds the default carrier frequency, the VFD needs to derate by 20% for each increase of 1k carrier frequency. Setting range: 1.0-16.0kHz| |

P01.07| Stop mode| 0: Decelerate to stop. After the stop command becomes valid, the VFD decelerates to decrease the output frequency during the set time. When the frequency decreases to the stop speed, the VFD stops.
1: Coast to stop: after the stop command becomes valid, the VFD ceases the output immediately. And the load coasts to stop at the mechanical inertia. And the load coasts to stop according to mechanical inertia.| 0| 0
P01.08| Starting
frequency of
DC braking for
stop| Starting frequency of DC braking for stop: During the deceleration to stop, the VFD starts DC braking for stop when running frequency reaches the starting frequency determined by P01.09.

Wait time before DC braking: The VFD blocks the output before starting DC braking. After this wait time, DC braking is started so as to prevent overcurrent caused by DC braking at high speed.

DC braking current for stop: It indicates the applied DC braking energy. Stronger current indicates greater DC braking effect.
DC braking time for stop: It indicates the hold time of DC braking. If the time is 0, DC braking is invalid, and the VFD decelerates to stop within the specified time. Setting range of P01.08: 0.00Hz—P00.04 (Max. output frequency)
