IC800SSI228RD2 Servo Motor Controller System Overview


The S-Series servo motors optimized for use with the S2K Series controllers range from

30 W to 5 kW and are rated for 230 VAC for full speed. Using a 115 VAC supply will result

in a reduced operating speed of approximately one half of the rated speed.

The 30 to 1.000 Watt S-Series servo motors (SLM models only), MTR-3S and MTR-3N

series and all stepping motor models are designed with standard NEMA shaft and flange

mounting configurations for easy mounting to off-the-shelf gear reducers and couplings.

The 750-Watt S-Series motor uses an oversized shaft diameter (0.625 inches) for the

NEMA 34 mounting in order to handle the peak torque rating of this model. 

S-Series motor models from 1 to 5 kW (except the SLM100 1kW motor) and all MTR-3T Series motors

have metric mounting configurations.

All servo motors are available with an optional 24 VDC holding brake. These brakes are

spring-set, electrically released models designed for holding stationary loads. The user

must supply a separate 24 VDC brake power supply. The 30-750 Watt S-Series motors

have a pigtail cable with box style connectors for motor power, encoder and brake

connections. The 1.000 to 5.000 Watt S-Series motors have MS style connectors and the

brake power (when required) is integrated with the motor power connections in a common

connector/cable. MTR-series servo motors include MS type connectors for brake power

input. The MTR-3N and MTR-3T series brake motors integrate the brake power with the

motor power in the same cable. MTR-3S brake motors require a separate brake power cable (CBL-30-BT).

IC800SSI228RD2 Servo Motor Controller supporting

Models supporting DeviceNet™ or PROFIBUS communications include 14 discrete I/O

points. The 4.3 and 7.2 amp servo models and the stepper model are also available with

21 I/O points instead of the DeviceNet or PROFIBUS communications. All drives are

capable of supporting the Modbus/RTU protocol. If the optional Modbus adapter is used

(catalog number IC800MBUSADP) the standard RS-232 serial port can be used for

multidrop applications. This adaptor is an externally mounted multi-drop RS-232 to RS485 serial port converter.

The S2K Series controllers are optimized for use with the GE Fanuc S-Series or MTRseries servo and stepping motors. 

Overload and possible component damage may occur

if the motor and amplifier are not properly matched. Tables 1-1 to 1-3 show the

recommended pairing of the components.

The S2K Series stepper controller requires a single-phase 115 VAC supply. S2K Series

servo controller models rated 230 VAC and 4.3 or 7.2 amp can operate on either 115 VAC

single-phase or 230 VAC three-phase, while the all other models are rated for three-phase

input. The 230 and 460 VAC models are intended to be operated from a three-phase

supply but can be used with a single-phase power source.

IC800SSI228RD2 Servo Motor Controller

System Overview

The S2K Series is a family of high performance standalone brushless servo or stepper

amplifiers with integrated motion controllers and user configurable I/O functions.

Controllers are available in models configured for either resolver or serial encoder motor

feedback. Encoder-based S2K servo models can be used only with GE Fanuc S-Series

(SLM, SDM or SGM) servo motors. S2K resolver feedback servo controllers use GE

Fanuc MTR-Series (3N, 3S or 3T) servo motors or third-party motors with appropriate

ratings and resolver specifications. Please consult the factory for assistance in controlling non-GE Fanuc motors.

Servo models support continuous stall torque from 0.84–478 in-lb (0.095–54 Nm) while

the stepper model supports holding torque from 144–3.074 oz-in (16.3–21.7 Nm). Servo

controller models include four 230 VAC ratings of 4.3. 7.2. 16. and 28 amps continuous

and two 460 VAC ratings of 7.2 and 20 amps continuous (460 VAC models are only

available with resolver feedback). Peak currents of the 230 VAC servo models are two

times the continuous ratings while the 460 VAC servo models are 1.5 times the

continuous rating. The stepper controller has a rating of 5 amps.

ABB RET615 ANSI Transformer Protection and Control Overview

Overview

RET615 is a dedicated transformer protection and control relay for power transformers,

unit and step-up transformers including power generator-transformer blocks in utility and

industry power distribution systems. RET615 is a member of ABB’s Relion® product

family and part of its 615 protection and control product series. 

The 615 series relays are characterized by their compactness and withdrawable-unit design.

Re-engineered from the ground up, the 615 series has been designed to unleash the full

potential of the IEC 61850 standard for communication and interoperability between

substation automation devices. Once the standard configuration relay has been given the

application-specific settings, it can directly be put into service.

The protection relay can support five simultaneous clients. 

If PCM600 reserves one client connection, only four client connections are left, for example, for IEC 61850 and Modbus.

All communication connectors, except for the front port connector, are placed on

integrated optional communication modules. 

The protection relay can be connected to Ethernet-based communication systems via the 

RJ-45 connector (100Base-TX) or the fiber optic LC connector (100Base-FX).

ABB REU610 Measurement Voltage Protection RELION® 610 SERIES

Protection functions

The protection relay offers integrated protection functions including two-stage 

overvoltage and undervoltage protection, two-stage residual overvoltage protection, 

as well as singlestage negative phase-sequence overvoltage protection and 

single-stage positive phase-sequence undervoltage protection.

Measurement

The protection relay physically measures the three phase-tophase voltages and the residual voltage of the power system.

Further, from the phase-to-phase voltages the protection relay

calculates the positive and negative phase-sequence voltages,

the one-minute average phase-to-phase voltage, the average

phase-to-phase voltage for a user-specifiable time frame, the

maximum value of the one-minute average voltage, and the

maximum and minimum phase-to-phase voltage value since last reset.

The values of the voltages measured or calculated can be

accessed locally via the user interface on the protection relay’s

front panel, or remotely via the serial communication interface

on the rear panel of the protection relay.

Disturbance recorder

The protection relay is provided with a built-in battery backedup digital 

disturbance recorder for four analog signal channels and eight digital signal channels. 

The analog channels can be set to record the curve form of the voltages measured. 

The digital channels can be set to record external or internal relay

signals, for example the start or trip signals of protection relay’s

stages, external blocking or control signals. Any digital relay

signal such as a protection start or trip signal, or an external

relay control signal can be set to trigger the recording. 

The recordings are stored in a nonvolatile memory from which the

data can be uploaded for subsequent fault analysis.

ABB REJ603 Measurement Self-powered feeder protection 605 series

Measurement

The relay continuously measures phase currents and earth current. Earth current can be

measured using external core balance current transformer or can be calculated internally.

The relay has provision to display measured three phase current and earth current in primary

and secondary terms. Additionally, relay displays status of binary input, binary output and trip

counter for over current and earth fault trip.

During service, the default view of display shows three phase current and the earth current in

secondary terms. The values measured can be accessed using on the local HMI.

Event log 

To collect sequence – of – events (SoE) information,

the relay incorporates a non-volatile memory with a capacity of storing 250 events

with associated time stamps with resolution of 1 ms.

Event log includes protection operation status, binary I/O status and relay fault code.

The event logs are stored sequentially,the most recent being first and so on.

The non-volatile memory retains its data also in case the relay temporarily loses its auxiliary supply.

The event log facilitates detailed post-fault analysis of feeder faults and disturbances.

The SoE information can be accessed locally via the user interface on the relay front panel.

ABB REJ603 Application Self-powered feeder protection 605 series

Application

The REJ603 is a protection relay aimed at selective short-circuit and earth-fault protection

of feeders in secondary distribution networks and for protection of transformers in utilities and industries.

The inrush current stabilization function allows the relay to be used as main protection of

distribution transformers.

The relay is powered up through current transformer if current is above energizing level of

relay, front USB power or through auxiliary supply (optional feature).

The relay offers, non-directional over current and earth-fault protection. 

The residual current for the earth-fault protection is derived from the phase currents. 

When applicable,the corebalance current transformers can be used for measuring the residual current,

especially when sensitive earth-fault protection is required.

The relay additionally offers thermal overload protection for feeders, cables and transformers.

There is optional provision of remote trip through binary input with external auxiliary power supply.

The remote trip signals like transformer trouble output (Buchholz, Oil temperature,

Winding temperature trip) or an external trip can be wired

to binary input. The remote trip function works even in CT-powered mode when auxiliary supply

is not available but enough CT current is available to power-up the relay.
