TOSHIBA TOSBERT TM VF-nC1 Industrial Inverter

TOSHIBA TOSBERT TM VF-nC1 Industrial Inverter

Product Overview

1.1 Basic Information

Model: TOSBERT TM VF-nC1 Industrial Inverter

Applicable motor: only for three-phase induction motors, cannot drive single-phase motors

Power and voltage specifications: covering three voltage levels, with specific parameters as shown in the table below:

Voltage level, power range (kW), model example, output current (A), suitable motor capacity (kW)

Single phase 100V level 0.1-0.75 VFNC1S-1001P 0.7-4.0 0.1-0.75

Single phase 200V level 0.2-2.2 VFNC1S-2002P 1.4-10.0 0.2-2.2

Three phase 200V level 0.1-2.2 VFNC1-2001P 0.7-10.0 0.1-2.2

Single phase 200V level (with filter) 0.2-2.2 VFNC1S-2002PL 1.2-10.7 0.2-2.2

Core control method: Adopting sine wave PWM control, the output frequency range is 0.5-200Hz (default 0.5-80Hz), and the voltage/frequency characteristics can be adjusted through parameters (V/f constant, sensorless vector control).

Safety regulations

2.1 Warning System

The manual divides safety warnings into two levels, clarifying the consequences of risks and operational requirements:

Typical scenario examples of warning type meanings

Warning: Incorrect operation may result in death or serious injury. Disassembling the front cover while live, connecting input power to output terminals, and operating without grounding

Incorrect handling of the solution may result in minor injuries or property damage. Touching the heat sink, using incompatible chemicals, and installing in a vibrating environment

2.2 Mandatory Safety Requirements

Grounding: D-type grounding (formerly Class 3 grounding) must be used, and the grounding wire diameter should be ≥ 3.5mm ² (refer to the terminal specification table for details) to ensure safe conduction of leakage current in case of fault.

Power off waiting: After disconnecting the input power, wait for at least 15 minutes to confirm that the charge light is off and the DC main circuit voltage is ≤ 45V before touching the terminal.

Installation base: It needs to be fixed on a metal base that can withstand the weight of the equipment to prevent it from falling; Choose NEMA 3R protection model (such as 5000 series) for outdoor/harsh environments.

Emergency stop: It must be equipped with an emergency stop device independent of the frequency converter (such as mechanical braking), and the frequency converter alone cannot achieve immediate shutdown.

Parameter settings

3.1 Parameter Classification and Core Parameters

Parameters are divided into three categories: basic parameters, extended parameters, and special parameters. The core parameters and functions are as follows:

Parameter Category Parameter Code Function Description Adjustment Range Default Values Key Role

Basic parameter CMod instruction mode selection (source of run/stop instructions) 0- Terminal board/1- Panel 1 Determine control mode

FMod frequency setting mode selection: 0- Terminal board/1- Panel, etc. 2. Determine the frequency adjustment method

ACC/DEC acceleration time 1/deceleration time 1 0.1-3000 seconds 10.0s to prevent current overload during startup/shutdown

FH/UL maximum frequency/upper limit frequency 30-200Hz/0.5-FH 80Hz/80Hz limits the maximum operating frequency of the motor

Extended parameter F300 PWM carrier frequency 2/4/8/12/16kHz 12kHz balanced motor noise and inverter losses

F250-252 DC braking parameters (starting frequency/current/time) 0.0-FHHz/0-100/0-20s 0.0Hz/50%/1.0s to achieve rapid shutdown

OLn electronic thermal protection characteristics 0-7 (corresponding to different protections) 0 adaptation standard motor/VF motor protection

Special parameter RUL wizard function (quick setting) 0-5 (5-class wizard) 0 Simplified parameter configuration (such as basic settings)

RUH History Record Function - Display the Last 5 Modified Parameters

3.2 Parameter Setting Process

Enter setting mode: Press the MON key to switch to "parameter setting mode" (display "RUH");

Parameter selection: Use the △/▽ keys to select the target parameter (such as CMod);

Modify parameters: Press the ENT key to enter editing, and then use the △/▽ keys to adjust the values;

Save parameters: Press the ENT key again, and the parameters and values will alternate to indicate successful saving;

Reset default: Set the basic parameter "Eyp" to 3 to restore all parameters to their factory default values (with the need to shut down first).

Installation and wiring

4.1 Installation environment requirements

Temperature: Operating environment temperature * * -10 ℃ -50 ℃ * *. When the ambient temperature is greater than 40 ℃, the warning label on the top of the equipment should be removed and the rated output current should be reduced (such as the current of the 2007P model dropping from 4A to 3.6A at 40-50 ℃);

Humidity: Relative humidity of 20% -93%, no condensation;

Vibration: Vibration acceleration<5.9m/s ² (10-55Hz), avoid installing near strong vibration equipment such as machine tools;

Other: No dust, corrosive gases, oil mist, keep away from heat sources (such as transformers, heaters).

4.2 Terminal Wiring Specification

Main circuit terminals:

Screw specifications: M3 (low power)/M3.5 (high power), tightening torque of 0.8N · m/1.0N · m respectively;
