YASKAWA 1000 series frequency converter

Inverter replacement: During replacement, parameter configuration can be transferred through a detachable terminal block to reduce the workload of reprogramming.

Peripheral Devices and Options

Peripheral Device Adaptation

Protective equipment: Molded Case Circuit Breakers (MCCBs), Residual Current Circuit Breakers, Thermal Relays (OL), etc. must be installed to comply with local electrical regulations.

Filtering and reactors: Input filters, EMC filters, and AC/DC reactors can be installed to reduce electromagnetic interference and improve input current waveforms.

Communication Options

Supports MEMOBU/Modbus communication protocols and can be adapted to more bus protocols by extending the communication card. Wiring must follow communication specifications and configure corresponding parameters (such as baud rate and address).

Technical Specifications and Parameter List

Core specifications

Output characteristics: Voltage range 0- input voltage, frequency range 0-400Hz, overload capacity of normal working mode 120%/60s, overload mode 150%/60s.

Protection function: including multiple protections such as overcurrent, overvoltage, overload, overheating, phase loss, and ground fault.

Parameter List

Parameter grouping: divided into initialization parameters (A), application parameters (b), adjustment parameters (C), motor parameters (E), terminal function parameters (H), protection function parameters (L), monitoring parameters (U), etc., covering all configurable items such as control mode, operating parameters, protection thresholds, etc. Each parameter is labeled with default values, configuration ranges, and functional descriptions.

Key technical points

Motor adaptation

Supports ordinary induction motors and permanent magnet synchronous motors (PM). Permanent magnet synchronous motors require motor code (E5-01) and related parameters (E5-02~E5-24) to be configured, and speed search function (b3-01=1) to be enabled.

Motor parameter configuration: Accurate input of motor rated current, number of poles, rated power, and other information is required, or automatically obtained through the Auto Ajuste function to ensure control accuracy.

Differences in Control Modes

V/f control: Suitable for ordinary speed regulation scenarios (such as fans and pumps), with a simple structure and support for multi motor control.

Open loop vector control: suitable for high-precision speed regulation and high starting torque scenarios (such as conveyors and cranes), requiring Auto Ajuste to optimize parameters.

Permanent magnet synchronous motor control: efficient and energy-saving, suitable for scenarios with variable torque and high energy efficiency requirements, requiring dedicated parameter configuration.

Core taboos for safe operation

Prohibited items: live wiring/plugging of components, use of single-phase motors, covering of heat dissipation ports, modification of internal circuits of frequency converters, use of mismatched voltage power supplies.

Required items: reliable grounding, operation after power outage and discharge, operation by qualified personnel, tightening terminals according to specifications, regular maintenance of cooling system.
