Toshiba TOSBERT S7 series frequency converter

Secondary menu: In parameter mode, it is divided into basic parameters (P00-P09), extended parameters (P10-P29), communication parameters (P20-P23), and fault parameters (P30-P39);

Third level menu: specific parameter items (such as P03.01=acceleration time 1).

2. Basic operation process (taking panel control as an example)

(1) Power on and standby

Close the input side circuit breaker (MCCB), power on the inverter, display the Toshiba logo on the screen, and enter the standby interface after about 3 seconds (display "0.0Hz", POWER indicator light on);

Check that there are no fault prompts on the panel (ALARM indicator light off), and confirm that the motor wiring is correct and there is no jamming.

(2) Frequency setting and startup

Press the "MODE" button to switch to the "Panel Control" mode (RUN indicator light flashes);

Rotate the parameter knob to set the target frequency (such as 50Hz), and the display screen will show the set value in real-time;

Press the "RUN" button, the RUN indicator light stays on, the frequency converter accelerates to the target frequency according to the acceleration time (P03.01), and the motor starts;

During operation, the frequency can be fine tuned through the parameter knob (range 0.0-400.0Hz), and no confirmation is required after adjustment, which takes effect in real time.

(3) Shutdown operation

Normal shutdown: Press the "STOP" button, the frequency converter decelerates and shuts down according to the deceleration time (P03.02), the RUN indicator light goes out, and the standby interface is restored;

Emergency stop: Press the external emergency stop button (DI7 terminal), and the frequency converter immediately executes the emergency stop mode (parameter P06.03 set, default deceleration stop). The ALARM indicator light flashes, and the emergency stop button needs to be reset before pressing the "RESET" button to restore.

(4) Fault detection and reset

When a fault occurs, the display screen shows a fault code (such as "OC1"), the ALARM indicator light stays on, and the frequency converter shuts down;

Press the "MODE" button to switch to fault mode, where you can view the cause of the fault and the current/voltage/frequency data at the time of the fault;

After troubleshooting, press and hold the "RESET" button or the "STOP" button for 2 seconds to reset the fault and restore standby mode.

3. External control and communication control operations

(1) External control (terminal control)

Parameter settings: P05.01=1 (external control mode), P06.01=0 (leakage type input);

Wiring: DI1 connected to forward switch, DI2 connected to reverse switch, AI1 connected to 0-10V frequency potentiometer;

Operation: Close the forward switch and start the motor according to the frequency command input by AI1; Disconnect the switch and the motor will slow down and stop.

(2) Communication Control (MODBUS-RTU)

Parameter settings: P05.01=2 (communication control mode), P20.01=3 (9600bps), P20.02=1 (slave address 1);

Upper computer configuration: Set MODBUS-RTU protocol and register address (such as frequency instruction register 0x0001);

Operation: The upper computer sends frequency commands (such as 50Hz corresponding to a value of 5000) and start commands, and the frequency converter performs the corresponding operations; The upper computer can read real-time operating data (such as current register 0x0002).

Core functions and parameter configuration

1. Control mode selection and configuration

The TOSBERT S7 series supports three core control modes, which can be flexibly selected according to the load type:

Control Mode Parameter Code (P01.01) Core Features Applicable Scenarios Key Configuration Parameters

V/f control has a simple structure, high stability, and is compatible with all asynchronous motors; Support linear/square/V/f custom curve fans, pumps, and ordinary conveyors (variable torque/constant torque load) P01.02 (V/f curve type), P01.03 (torque boost)

Sensorless Vector Control (SVC) 1 does not require an encoder and outputs 150% of the rated torque at 0.5Hz; Speed accuracy ± 0.1% for machine tools, cranes, and packaging machines (high-precision, high torque starting) P01.04 (vector control gain), P04.01 (torque limit)

Sensor Vector Control (FVC) 2 requires an external encoder with a speed accuracy of ± 0.01%; Support zero speed torque holding elevators, elevators, precision machine tools (ultra-high precision speed regulation, positioning) P02.01 (encoder type), P02.02 (encoder resolution), P04.08 (zero speed holding enabled)

2. Torque control function (parameter P04 group)

(1) Core torque parameters

Parameter Code Parameter Name Adjustment Range Default Value Function Description

P04.01 Positive torque limit 0.0-200.0% 150.0% Limit the maximum torque of the motor during forward operation to prevent overload

P04.02 Reverse torque limit 0.0-200.0% 150.0% Limit the maximum torque of the motor during reverse operation

P04.05 Torque control enable 0=disabled, 1=enabled 0. After enabling, the frequency converter runs according to the torque command (AI2 input)
