YASKAWA CIMR-M5D2018 High Performance Inverter

YASKAWA CIMR-M5D2018 High Performance Inverter

Core technical parameters and performance advantages

The CIMR-M5D2018 inverter adopts a 200V level three-phase power supply design, with a rated output power of up to 18.5kW, which can accurately match three-phase asynchronous motors of the same power level, providing strong and stable power output for the equipment. In terms of core control technology, this model is equipped with Yaskawa's patented vector control algorithm, which can achieve high-precision control of motor speed and torque. The speed control accuracy reaches within ± 0.5%, and even under low-speed operating conditions, it can maintain stable torque output, effectively solving the problems of low-speed vibration and insufficient torque in traditional frequency converters.

In addition, the inverter has excellent dynamic response performance, and the acceleration and deceleration time can be flexibly adjusted within the range of 0.1-3600 seconds. It can quickly adapt to the start stop requirements of different loads, reduce the impact current during equipment startup, and extend the service life of motors and mechanical transmission components. In terms of energy conservation, CIMR-M5D2018 is equipped with advanced energy-saving operation mode, which can automatically adjust the output frequency according to load changes. When the equipment is in light load condition, the output power is automatically reduced. Compared with traditional power frequency operation mode, it can achieve 10%~30% energy savings, especially suitable for variable load conditions such as fans and pumps.

Comprehensive security protection function

To ensure the safety of equipment and operators, the CIMR-M5D2018 inverter integrates multiple comprehensive protection functions, covering various abnormal working conditions such as overcurrent, overload, overvoltage, and power outage, effectively reducing the risk of equipment failure and improving the reliability of system operation. The specific protection functions are as follows:

-Instantaneous overcurrent protection: When a fault such as a short circuit occurs on the load side of the inverter circuit, causing the current flowing through the inverter device to exceed the allowable value, the equipment will instantly stop the inverter operation and cut off the current; If the output current of the inverter reaches an abnormal value, the same protection mechanism will be triggered to prevent device damage due to overcurrent.

-Overload protection: Adopting inverse time characteristic protection design, when the output current of the inverter exceeds the rated value and the duration reaches the specified threshold, in order to avoid damage to the inverter components, wires, etc. due to overheating, it will automatically stop running. This protection function can effectively deal with overload problems caused by excessive load inertia or motor stalling.

-Regenerative overvoltage protection: Under the condition of rapid deceleration of the inverter driven motor, the motor will be in a generating state, and the generated regenerative power will cause the DC circuit voltage to rise. When the voltage exceeds the allowable value, the equipment will prevent damage to circuit components caused by overvoltage by stopping the inverter operation or slowing down the deceleration speed.

-Instantaneous power outage protection: For millisecond level instantaneous power outages, the control circuit can maintain normal operation; If the instantaneous power outage lasts for more than tens of milliseconds, not only may the control circuit malfunction, but the main circuit may also lose power due to the power outage. At this time, the equipment will detect the power outage state and stop the inverter operation to avoid abnormal startup of the equipment when power is restored.

-Grounding overcurrent protection: When a grounding fault occurs in the inverter load, this function will quickly respond and cut off the circuit to protect the inverter body; At the same time, to ensure personal safety, the equipment has reserved a linkage interface with the leakage protection circuit breaker, which needs to be used in conjunction with external leakage protection devices.

-Abnormal protection of cooling fan: The equipment is equipped with an independent cooling fan to dissipate the heat generated during operation. When the fan stops abnormally or the speed is insufficient, the temperature of the device's heat sink will increase. At this time, the temperature sensor will detect the abnormality and trigger the protection mechanism to stop the inverter from working, preventing equipment failure caused by overheating.

Installation and commissioning precautions

To ensure the safe and stable operation of CIMR-M5D2018 inverter, the following precautions must be strictly followed during installation and commissioning:

（1） Preparation before installation

1. Environmental inspection: The equipment should be installed in a compliant environment, avoiding installation in places with high temperature, high humidity, high dust, corrosive gases, or severe vibration. The ambient temperature should be controlled within the range of -10 ℃ to 40 ℃, and the relative humidity should not exceed 90% (no condensation).

2. Static electricity protection: The electronic components inside the equipment are sensitive to static electricity, and static electricity protection measures should be taken before installation. Operators should wear anti-static wristbands, and the equipment should be stored in protective packaging until it is removed during installation. Do not touch exposed conductive parts (such as contacts, terminals, etc.) to avoid static electricity damaging the components.

3. Power supply confirmation: Before installation, it is necessary to confirm that the input power supply voltage is consistent with the rated voltage of the equipment (200V three-phase) to avoid equipment damage caused by voltage mismatch; At the same time, it is necessary to check whether there are short circuits, poor contacts, and other issues in the power supply circuit.

（2） Installation and wiring specifications

1. Power off operation: Before installation or wiring work, all external power sources (including the power supply of connected devices) must be cut off, and a suitable rated voltage sensing device must be used to detect whether the power is off, in order to prevent the danger of electric shock or arc flash.

2. Wiring confirmation: It is necessary to strictly follow the terminal arrangement diagram in the product manual for wiring, confirm that the input and output lines are connected correctly, and avoid wiring errors. When connecting wires, it is necessary to ensure that the wire specifications match the rated current of the equipment, and to tighten the wire bolts within the specified torque range. Loose bolts may cause short circuits, fires, or misoperations, while tight bolts may cause damage to the bolts and terminals, leading to problems such as dropping and short circuits.

3. Foreign object protection: During installation, attention should be paid to avoiding foreign objects such as chips, connectors, dust, etc. from entering the interior of the inverter. Foreign objects may cause circuit short circuits, equipment failures, or misoperations.

4. Grounding requirements: The equipment must be reliably grounded, and the grounding resistance must comply with local electrical regulations. Good grounding can effectively prevent static electricity accumulation and leakage accidents, ensuring the safety of the equipment and operators.

（3） Debugging and operation precautions

1. Pre commissioning inspection: After installation and wiring are completed, it is necessary to confirm again that the circuit connection is correct and there is no looseness or misconnection; Check whether the cooling fan is installed properly and whether it rotates flexibly; Confirm that all protective covers and accessories have been securely installed.

2. Parameter setting: Based on the load type and operating requirements, relevant parameters such as motor rated voltage, rated current, speed range, acceleration/deceleration time, etc. can be set through the equipment panel or supporting software. After the parameter settings are completed, it is recommended to conduct a trial run to observe whether the equipment is operating normally.

3. Trial operation testing: During the trial operation process, it is necessary to focus on checking whether the motor speed is stable, whether there are any abnormal vibrations or noises; Whether the output current and voltage of the inverter are normal; Is the cooling system working properly and is the surface temperature of the equipment within a reasonable range. If any abnormal situation occurs, the operation should be stopped immediately, and the fault should be investigated before re debugging.

4. Prohibition of illegal operations: During the debugging process, it is prohibited to dismantle the equipment cover or modify the internal circuit at will; Do not touch terminals or conductive parts while the device is running; It is strictly prohibited to operate beyond the rated parameters of the equipment to avoid equipment damage caused by overload, overvoltage, etc.
