2.2.1. AC Power Connections AC input power to the Epaq MR drive chassis is applied to the AC power receptacle that is located on the rear panel. The power cord connected to this receptacle also provides the protective earth ground connection and may serve as a Mains disconnect.
The shield of the cables must be connected to the metal back shell in order for the product to conform to the radiated emission standards. 5. The Epaq MR is a component designed to be integrated with other electronics. EMC testing must be conducted on the final product configuration.
Installation and Configuration Epaq MR Hardware Manual 2.2.3. I/O and Signal Wiring Requirements The I/O, communication, and encoder feedback connections are typically very low power connections. In some applications, especially when there are significant wire distances, a larger wire size may be required to reduce the voltage drop that occurs along the wire.
Epaq MR Hardware Manual Installation and Configuration 2.2.4. Voltage Selection You can reconfigure the transformers primary windings to support different AC line voltages by changing the Voltage Selection switches that are located on the left side of the chassis. The Voltage Selector can only be used with transformer-derived bus voltages.
Epaq MR Hardware Manual 2.3. Motor Output Connections The Epaq MR can be used to drive three motor types: Brushless, DC Brush, and Stepper motors. The DC brush, brushless, and stepper motor connections are made to the 5-pin high power “D” style motor power connectors (Axis 1-8) that are located on the rear panel.
Brushless Motor Configuration Brushless motors are commutated electronically by the controller, typically using Hall-effect devices. If you are using standard Aerotech motors and cables, motor phasing adjustments are not required and this section may be skipped. The controller requires that the Back-EMF of each motor phase be aligned with the corresponding Hall-effect signal.
Installation and Configuration Epaq MR Hardware Manual 2.3.1.1. Powered Motor Phasing Refer to the Motor Phasing Calculator in the Configuration Manager for motor, Hall, and encoder phasing. Feedback Monitoring The state of the encoder and Hall-effect device signals can be observed in the Motion Composer.
With the designations of the motor and Hall leads of a third party motor determined, the motor can now be connected to an Aerotech system. Connect motor lead A to motor connector A, motor lead B to motor connector B, and motor lead C to motor connector C. Hall leads should also be connected to their respective feedback connector pins (Hall A lead to the Hall A feedback pin, Hall B to Hall B, and Hall C to Hall C).
When the voltmeter indicates a positive value, the motor leads have been identified. 5. Connect the motor lead from the voltmeter to the ØA motor terminal on the Epaq MR. Connect the motor lead from the negative lead of the voltmeter to the ØC motor terminal on the Epaq MR.
Stepper Motor Configuration 2.3.3.1. Stepper Motor Phasing N O T E : If using standard Aerotech motors and cables, motor and encoder connection adjustments are not required. A stepper motor can be run with or without an encoder. If an encoder is not being used, phasing is not necessary.
Installation and Configuration Epaq MR Hardware Manual 2.4. Motor Feedback Connections The motor feedback connector (a 25-pin, D-style connector) has connections for an encoder, limit switches, Hall-effect devices, motor over-temperature device, 5 V encoder and limit power, and optional brake connections.
Installation and Configuration 2.4.1. Encoder Inputs The Epaq MR is equipped with standard and auxiliary encoder feedback channels. The standard encoder interface is accessible through the Motor Feedback connector. By default, it accepts an RS-422 differential line driver signal. If the -MXU or -MXH option has been purchased, the standard encoder interface has been configured for an analog encoder input via parameter settings.
Installation and Configuration Epaq MR Hardware Manual 2.4.1.1. RS-422 Line Driver Encoder (Standard) The standard encoder interface accepts an RS-422 differential quadrature line driver signal. Invalid or missing signals will cause a feedback fault when the axis is enabled. An analog encoder is used with the -MXH/-MXU option (refer to Section 2.4.1.2.
Epaq MR Hardware Manual Installation and Configuration 2.4.1.2. Analog Encoder Interface If the -MXH/-MXU option has been purchased, the standard encoder channel will accept a differential analog encoder input signal. The interpolation factor is determined by the EncoderMultiplicationFactor parameter and is software selectable (refer to the Ensemble Help file).
Epaq MR Hardware Manual Installation and Configuration 2.4.1.3. Encoder Phasing Incorrect encoder polarity will cause the system to fault when enabled or when a move command is issued. Figure 2-17 illustrates the proper encoder phasing for clockwise motor rotation (or positive forcer movement for linear motors).
Epaq MR Hardware Manual Installation and Configuration 2.4.2. Hall-Effect Inputs The Hall-effect switch inputs are recommended for AC brushless motor commutation but not absolutely required. The Hall-effect inputs accept 5-24 VDC level signals. Hall states (0,0,0) or (1,1,1) are invalid and will generate a "Hall Fault"...
Installation and Configuration Epaq MR Hardware Manual 2.4.3. Thermistor Input The thermistor input is used to detect a motor over temperature condition by using a positive temperature coefficient sensor. As the temperature of the sensor increases, so does the resistance. Under normal operating conditions, the resistance of the thermistor is low (i.e., 100 ohms) which will result in a low input...
Epaq MR Hardware Manual Installation and Configuration 2.4.4. Encoder Fault Input The encoder fault input is for use with encoders that have a fault output. This is provided by some manufactures and indicates a loss of encoder function. The active state of this input is parameter configurable and the controller should be configured to disable the axis when the fault level is active.
Installation and Configuration Epaq MR Hardware Manual 2.4.5. End Of Travel Limit Inputs End of Travel (EOT) limits are used to define the end of physical travel. The EOT limit inputs accept 5-24 VDC level signals. The active state of the EOT limits is software selectable by the EndOfTravelLimitSetup axis parameter (refer to the Ensemble Help file).
Epaq MR Hardware Manual Installation and Configuration 2.4.5.1. End Of Travel Limit Phasing If the EOT limits are reversed, you will be able to move further into a limit but be unable to move out. To correct this, swap the connections to the CW and CCW inputs at the motor feedback connector. The logic...
Installation and Configuration Epaq MR Hardware Manual 2.4.6. Brake Output The Brake Output is a factory wired option allowed for one or more axes. The brake pins are used to automatically control a fail-safe brake (typically used on a vertical axis). The I/O option is required for each axis with a brake.
Epaq MR Hardware Manual Installation and Configuration 2.4.7. Differential Analog Input 0 To interface to a single-ended (non-differential) voltage source, connect the signal common of the source to the negative input and the analog source signal to the positive input. A floating signal source should be...
Installation and Configuration Epaq MR Hardware Manual 2.5. Digital / Analog IO Connections The IO connections includes 8 digital opto-inputs, 8 digital opto-outputs, 1 analog input, 1 analog output, a second encoder channel, and a brake/relay output. This connector is installed only if the -IO option has been ordered for the axis.

2.5.2. Analog Output 1 The analog output is set to zero when power is first applied to the system or during a system reset. N O T E : The Epaq MR does not have an "Analog Output 0". Table 2-24: Analog Output Specifications (TB102 B)
Epaq MR Hardware Manual Installation and Configuration 2.5.3. Opto-Isolated Outputs The digital outputs are optically-isolated and may be connected in sourcing or sinking configurations. The digital outputs are designed to connect to other ground referenced circuits and are not intended to provide high-voltage isolation.
Epaq MR Hardware Manual Installation and Configuration 2.5.4. Opto-Isolated Inputs The digital inputs are opto-isolated and may be connected to current sourcing or current sinking devices, as shown in Figure 2-29 Figure 2-30. These inputs are designed to connect to other ground-referenced circuits and are not intended for high-voltage isolation.
Epaq MR Hardware Manual Installation and Configuration 2.6. Aux Encoder The auxiliary encoder interface accepts a RS-422 differential quadrature line driver signal. This encoder channel can be used as an input for master/slave operation (handwheel), for dual feedback systems, or as an output to echo the standard encoder signals.
Dual-Axis Tracking 220 nsec Signals in excess of this rate will cause a loss of PSO accuracy. The optocoupler that you use on the output might have an effect on this rate. Epaq MR with ML drives Chapter 2 www.aerotech.com...
Installation and Configuration 2.7. Communications Connector The Ethernet connector (Communications) provides a 10/100 Ethernet connection to the Epaq MR controller. This can be connected directly to a hub or switch, or to a PC using a crossover cable. This port is viewed by the supplied software applications to communicate with the controller.
2.8. Ext Drive Connector The EXT DRIVE connector allows additional external drives to be connected to the Epaq MR chassis. This must be done using a CAT-6 shielded cable configured for the Epaq MR to the drive's Aeronet input. EXT DRIVE FEEDBACK...
Epaq MR Hardware Manual Installation and Configuration 2.9. RS-232 Interface The RS-232 port can be used for simple ASCII communications with another device. A one-to-one cable (not a null modem) is required for connection to a PC. RS232 FEEDBACK COMMUNICATIONS...
