The Yaskawa SGDM-04ADA Servopack is high-performance, easy-to-use servo drive. It has shortened settling time with its upgraded control algorithms that use model follow-up and vibration suppression. It also touts high accuracy, high speed, and smooth operation that reduces motor speed ripples. The SGDM-04ADA can support a wide range of motor specifications, including 100VAC motors, single-phase from 0.03 to 0.2kW; 200VAC motors, single phase from 0.3 to 0.4kW; and 200VAC three-phase motors from 0.45 to 7.5kW.
The SGDM-04ADA also is built for easy set up and maintenance. With its online-autotuning feature, all a user needs to do is plug in and let the Servopack run. The unit’s enhanced inertia matching precision gets rid of the need for servo gain adjustment. The use of the serial encoder allows for the SGDM-04ADA to automatically sense motor capacity and type, which lets it automatically set motor parameters. The module also has built-in cumulative load factor monitoring and regenerative load ratio monitoring. It can connect to standard PC interfaces to allow for waveform display monitors, and can also be controlled through a digital operator, even without inputting speed commands.
There are a few precautions to take before putting your SGDM-04ADA into operation. Firstly, never connect a 3-phase power supply to the U, V, or W output terminals as this could result in injury or fire. It is also crucial that users never touch the power terminals on their Servopack for at least 5 minutes after turning the power Off since high voltages could still be present. One should also install the battery at either the host controller or the Servopack of the encoder. If both batteries are installed simultaneously, there will be a loop circuit between the batteries.
The Yaskawa V1000 is a compact current vector drive with dual microprocessor logic. There are 3 primary models: 200V 3-Phase Input, 200V Single-Phase Input, and 400V 3-Phase Input. It is possible to run the drive without connecting the digital I/O wiring.
It is important when installing Yaskawa V1000 drives that proper electrostatic discharge (ESD) procedures are taken. Failure to comply could result in an ESD discharge that could damage the drive circuitry. If the drive is being operated at low speeds, the cooling effects are diminished and motor temperatures can increase which can lead to overheating. Continuously operating an oil-lubricated motor in the low speed range may result in burning.
A dynamic braking resistor can be used with the V1000 series. Dynamic braking helps bring the motor to a smooth and rapid stop when it is working with loads of high inertia. As the drive lowers the frequency of a motor with high inertia connected, regeneration occurs. This can cause over-voltage when the regenerative energy flows back into the DC bus capacitors. A braking resistor can help prevent these overload errors from occurring.
The drive functions are devided into 2 primary groups that are accessible through the Yaskawa V1000’s digital LED operator. Drive mode allows for motor operation and parameter monitoring. Parameter settings cannot be changed when functions are accessed in drive mode. However, alarm information and history can be accessed in drive mode. Programming mode allows access to the setup. There you can adjust and verify drive parameters as well as Auto-Tuning. The drive will not allow motor operation changes such as start and stop when the LED is accessing a function Programming mode. The V1000 is set to Drive mode when it is first powered up. The Up and Down arrow keys can be used to switch displays.
The CIMR-AU4A0038FAA is a three-phase 400 Volt AC Drive. There are two modes on this AC drive – Programming Mode and Drive Mode. In Drive Mode, the user can operate the motor and observe U monitor parameters. Parameter settings cannot be changed or edited while in Drive Mode. In Programming Mode, the user can edit and verify parameter settings and perform Auto-Tuning. When the drive is in Programming Mode, it will not accept a Run command unless b1-08 is set to 1. If b1-08 is set to 0, the drive will only accpet a Run command in Drive Mode. After editing the parameters, the user must exit the Programming Mode and enter Drive Mode before operating the motor.
Local mode is when the drive is set to accept the Run command from the digital operator RUN key. Remote mode is when the drive can be set to accept the Run command from an external device, such as input terminals or serial communications. Switch the operation between Local and Remote using the LO/RE key on the digital operator or via a digital input. After selecting local, the LO/RE light will remain lit. The CIMR-AU4A0038FAA will not allow the user to switch between Local and Remote during run.
Several Application Presets are available to facilitate setting up the drive for commonly used applications. Selecting one of these presets automatically assigns functions to the input and output terminals and sets a predefined number of parameters to values appropriate for the selected application. An Application Preset can either be selected from the Application Selection menu in the Setup Group or in parameter A1-06. The default parameter setting is 0, which disables the presets. The following setting ranges are listed below:
– 0: Disabled
– 1: Water supply pump
– 2: Conveyor
– 3: Exhaust fan
– 4: HVAC
– 5: Compressor
1. Be certain your input voltage source, motor, and drive name plates are all marked either 230V, 460V, or 575V. Other voltages can be used, but they require additional programming.
2. Mount drive on vertical surface with adequate space for air circulation.
3. Remove front cover, fit conduit to bottom plate, and connect power and ground wires.
Caution: Be certain you connect power to terminals L1, L2, and L3 only, or serious damage will result. Connect motor to T1, T2, and T3 only.
Installation of External Run/Stop Switch and Speed Potentiators:
Important: Complete the Installation and Keypad Operation before attempting external control.
Disconnect power, remove cover, and wait for “CHARGE” light to go out.
Connect a switch to terminals 1 and 11 using two conductor shielded wire. This circuit is 24Vdc, very low current; use a quality rotary or toggle switch (all wire should be 14-18AWG). Connect the shield to terminal 12 on the drive end only.
Install a single conductor “jumper wire” between drive terminals 5 and 11.
Connect a manual speed potentiometer rated 2000-3000 ohms, 1 watt minimum, using three conductor shielded wire, with shield connected at terminal 12. Connect wires to the potentiometer. Trace wire closest to the top and connect to terminal 17. Trace center wire of potentiometer through and connect to terminal 16. The remaining wire will be connected to the trim pot in step 5.
Connect a trim potentiometer rated 2000-3000 ohms, 1 watt minimum, as close to the drive terminals as possible. Viewing the potentiometer from the back, connect a single conductor wire from the left terminal to terminal 15 of the drive. Connect a short jumper wire between the center and left terminals. Connect remaining wire from manual speed pot as shown.
Industrial robotics are pretty under recognized. It’s easy to think they’re all about manufacturing. But just watch as Motoman-MH24, normally found assembling or packing products in a factory, takes on a new lease on its automation life and becomes a master sword fighter.
Motoman-MH24 is a 630-pound high-speed industrial robot made by Japan’s Yaskawa Electric Corporation. The Yaskawa Bushido Project is a short video clip showing Japanese master swordsman and five times Guinness World Record holder Isao Machii teach Motoman-MH24 the way of the sword. The company made this promotional clip to celebrate what they dub “manufacturing spirit” as they near their 100th anniversary.
To date, Machii has demonstrated some pretty radical feats with his blade: slicing a flying shrimp pelleted at him at 80mph in half, and a neon ball flung at him at 150mph – and these are just some of the things the dude can do.
The Yaskawa researchers examined Machii’s sword techniques in 3D. Next, they got Motoman to reproduce the very same movements, and the results are superb. In a showdown between master and robo-apprentice, the pair first demonstrate a four-directional cut in flawless sync. Then Motoman-MH24 reproduces each of Machii’s cuts down to a tee.
Things start really heating up when the robot actually looks like it’s gaining an upper hand over its human trainer. While Machii horizontally slices one orange, Motoman-MH24 takes down six in one fell swoop. The most epic scene is probably the one where Motoman splices a really thin pea pod in half.
While Machii looks visibly tired towards the end of the final “1000 cuts” scene, his mechanical counterpart could probably go on for at least an extra 100000.
To maintain a working SERVOPACK, there are a series of procedures to follow for inspection. The following steps should be followed at least once a year in order to ensure the best condition for your machine.
