Modicon 140AVI03000

Modicon Quantum 140AVI03000 – Product Spotlight

The 140AVI03000 is a Analog Mixed Current/Voltage Input Modules that is part of the Modicon Quantum series. This Analog In 8 Channel Bipolar Modules accepts a mix of current and voltage inputs. Jumpers are required between the input and sense terminals for current inputs. The 140-AVI-030-00 contains a total of 18 LEDs. The “Active” LED remains on and green when Bus communication is currently present. The “F” indicator will light up red when an error external to the module has been detected. The green LEDs 1 through 8 will turn on when the indicated point or channel is ON. The red 1 through 8 LEDs when light up for two reasons. Either the indicated channel is out of range (1 – 5 Volts), or a broken wire condition has been detected (4 – 20 mA).

To prevent improper fault indications, unused inputs should have the + (plus) and – (minus) inputs tied together and be configured for a bipolar input range. Unwired inputs can cause invalid readings. When configured for voltage inputs (no jumper is installed between Input (+) and ISENSE terminals), a broken field wire can cause readings to be non-zero and unpredictable. The field wiring terminal must not be removed when the module is in operation.

The following figure shows the 140-AVI-030-00 Wiring Diagram.

For external wiring, the user should supply the current and voltage sources, and installation and calibration of the fuses are at the discretion of the user. It is recommended that shielded cables are used, and twisted shielded cables should be used in noisy environments. The shielded cables should be connected to the PLC’s ground. A shield bar should be used to connected the shielded cable to the ground. If you are field wiring the 140AVI03000, the maximum wire size is 1-14 AWG or 2-16 AWG and the minimum wire size is 20 AWG.

Siemens Micromaster 420 Faults and Alarms

A blog we posted earlier this week about the Micromaster 420 troubleshooting referenced the Faults and Alarms list for the Micromaster series, so we decided that it would make sense to make the list of Micromaster 420 Faults and Alarms directly available. This is from the corresponding manual for the Micromaster 420 series, but it is buried within the manual which most people most likely don’t even have. Hopefully this helps with your troubleshooting.

Yaskawa V1000 – Compact Vector Control Drive

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.

Modicon Quantum 140CPU65150 – Product Spotlight

The 140CPU65150 is a Unity processor in Schneider Electric’s Modicon Quantum series. It is one of the newer models in the series of processor modules. It joins together the standard functions of the PLC and the diagnostic possibilities of a web server. It communicates using an RJ-45 connection. The module is in a double-width standard Quantum housing which requires two sequential slots in a Quantum rack. Because its web server functions are diagnostic only, software must be used to configure its services.

It has a clock frequency of 166 Mhz and has two local racks. It has 63 distributed I/O stations, 1 rack, and 3 distributed networks. It has 8000 discrete inputs and outputs of discrete in a distributed network, and 31744 discrete inputs and inputs in a remote system.  As far as application specific I/O, it can be used for time stamping, as a counter, for high-speed interrupt inputs, and as a serial link.

There are 6 optional modules that can be used with the 140CPU65150. These include, Ethernet, Modbus, Modbus Plus, Profibus DP, and Sy/Max. In a local AS interface, the module has an unlimited maximum number of connections. It also has 4 integrated connection types – Ethernet TCP/IP, Modbus, Modbus Plus, and USB. It has an expandable 8 MB of file storage, 7168 kB or expandable programming, and 768 kB of RAM. The 140CPU65150 uses a key switch memory port for on/off functionality.

The 140CPU65150 has a data rate of 10/100 Mbps. For a medium, a user should used a shielded twisted pair cable. The module has a number of services, including standard web service, Modbus TCP messaging, I/O scanning services, global data, FDR client, SNMP management, and SMTP services (email). It is compatible only with the Unity Pro software.

MRO Electric and Supply carries the 140CPU65150. For more product information or to request a replacement module, email sales@mroelectric.com or call 800-691-8511.

Modicon 140CRA31200 RIO Drop E/IP Adapter – Product Spotlight

The 140CRA31200 is a Ethernet RIO drop adapter in the Modicon Quantum series. It has 3 ports and uses the Ethernet IP/Modbus TCP communication port protocol. It can handle two integrated connection types: the Ethernet IP/Modbus TCP through the service port or through the device network. It is compatible with the 140CRP31200.

The 140CRA31200 has a number of local signalling channels. 1 green LED for RUN, 1 green/red LED for module status, 1 green/red LED for network communication status, and 1 red LED for I/O. This adapter module consumes one slot in the main (first) rack of the in Quantum remote drops. The extended (second) rack in a Quantum remote I/O drop does not require an adapter.

To set the location of the Ethernet remote I/O drop on the network, use the rotary switches on the front of the 140CRA31200 before you apply power to the module and before you download the application. The values that are set are applied during a power cycle. If the switch settings are change after the module has powered up, the Mod Status LED is activated and a mismatch message is logged in the module’s diagnostic system.

Because new values on the rotary switches are implemented on at the next power cycle, it is recommended that you set the values before starting the module. Valid values are from 00 to 159. These rotary switches can be manipulated on the 140CRA31200 with a small flat tipped screwdriver, and no software is required to configure or enable the rotary switches. Do not use the Stored and Clear IP settings on the Ones rotary switch, and keep in mind that the functionality of these settings do not apply to remote I/O installations.

MRO Electric and Supply carries new and refurbished Modicon 140CRA31200s. For more product information or to request  quote, email sales@mroelectric.com or call 800-691-8511.

Yaskawa CIMR-AU4A0038FAA A1000 Drive – Product Spotlight

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
