ABB robot power module DSQC661 3HAC026253-001 control cabinet Power Supply

Description

DSQC661 The EnerVista 745 Setup software now prepares the 745 to receive the new firmware file.

The 745 will display a message indicating that it is in Upload Mode. While the file is being

loaded into the 745, a status box appears showing how much of the new firmware file has

been transferred and how much is remaining, as well as DSQC661 the upgrade status. The entire

transfer process takes approximately five minutes.

The EnerVista 745 Setup software will notify the user when the 745 has finished loading

the file.

 Carefully read any displayed messages and click OK to return the main

screen.

Note

Cycling power to the relay is recommended after a firmware upgrade.

After successfully updating the 745 firmware, DSQC661 the relay will not be in service and will

require setpoint programming. To communicate with the relay, the following settings will

have to be manually programmed.

SLAVE ADDRESS

COM1/COM2/FRONT BAUD RATE

COM1/COM2/FRONT PARITY (if applicable)

When communications is established, the saved setpoints must be reloaded back into the

relay. See Loading Setpoints from a File on page 4–26 for details.

Modbus addresses assigned to firmware modules, features, settings, and corresponding

data items (i.e. default values, DSQC661 minimum/maximum values, data type, and item size) may

change slightly from version to version of firmware.

The addresses are rearranged when new features are added or existing features are

enhanced or modified. The EEPROM DATA ERROR message displayed after upgrading/

downgrading the firmware is a resettable, self-test message intended to inform users that

the Modbus addresses have changed with the upgraded firmware. This message does not

signal any problems when appearing after firmware upgrades.

While the interface is in either on-line or off-line mode, data generated by triggered

specified parameters can be viewed and analyzed via one of the following:

• Event recorder: The event recorder captures contextual data associated with the

last 256 events, listed in chronological order from most recent to the oldest.

• Oscillography: The oscillography waveform traces and digital states provide a

visual display of power system and relay operation DSQC661 data captured during specific

triggered events.

4.6.2 Waveform Capture (trace memory)

The EnerVista 745 Setup software can be used to capture waveforms (or view trace

memory) from the 745 relay at the instance of a trip. A maximum of 128 cycles can be

captured and the trigger point can be adjusted to anywhere within the set cycles. A

maximum of 32 waveforms can be buffered (stored) with the buffer/cycle trade-off.

The following waveforms can be captured:

• Phase A, B, and C currents (I a, I b, and I c)
• Differential A, B, and C currents (I diffa, I diffb, and I diffc)
• Ground currents (I g)
• Phase A-N, B-N, and C-N voltages (Va, Vb, and Vc)
• Digital data for output relays and contact input states
