Ordering Information 6-47 E-621 E-621.SR LVPZT Amplifier & Servo-Controller Module, Strain Gauge Sensor, RS-232 Interface E-621.LR LVPZT Amplifier & Servo-Controller Module, LVDT Sensor, RS-232 Interface E-500.621 Basic Chassis, 19”, for up to 12 Modules, Including Power Supply E-501.621 Basic Chassis, 9.5”, for up to 4 Modules, Including Power Suppy Technical Data LVPZT Amplifier & Servo-Controller Module with High-Speed RS-232 Interface � Integrated 20-Bit High- Speed RS-232 Interface � Network Capability with up to 12 Channels � For LVDT and Strain Gauge Position Sensors The E-621 is a newly developed improvement on the E-610-series modular controller/amplifier for low-voltage PZTs and offers the full functionality of that line. In addition, the E-621 is equipped with an RS-232 interface and command interpreter, the submodule. New and Fast Communications Interface The RS-232 interface handles the communications with the outside world. It performs up to 300 read or write operations per second and incorporates Models E-621.SR, E-621.LR Function Power amplifier & position servo-control of LVPZTs Channels Amplifier 1 Maximum output power 14 W Average output power 6 W Peak output current < 5 ms 140 mA Average output current 60 mA Current limitation Short-circuit proof Voltage gain 10 +/- 0.1 Polarity Positive DC-offset setting 0 to +100 V Input Impedance 100 k� Dimensions 7T wide, 3H high Operating voltage 13 to 30 VDC, stabilized Operating current RS-232 Interface 2 A D/A converter 20-bit resolution A/D converter (sensor) 20-bit resolution Baudrate 9.6 kBaud – 115.2 kBaud (default 115.2) Wave table Position Servo-Control 64 values, 100 Hz, externally triggered (in preparation) Sensor types Strain gauge (E-621.SR), LVDT (E-621.LR) Servo characteristics Connectors P-I analog, notch filter PZT connector LEMO ERA.00.250.CTL Sensor connector LEMO EPL.0S.304.HLN Analog input SMB Monitor output SMB RS-232 9-pin sub-D (male) http://www.pi.ws info@pi.ws E-621 Module precision 20-bit D/A and A/D converters for exceptional positional stability and resolution. The sub-module assumes all communications tasks with the host PC and/or with other networked modules in the system. Multi-Axis Network Communications between several E-621s with any combination of SGS and LVDT sensors, is also handled by the interface sub-module. Up to 12 modules can be networked and controlled over a single RS-232 interface. The different modules are connected in parallel (not daisy-chained) over the link. A special chassis (E-500.621) is available for up to 12 E-612 modules. It automatically provides the power and network connections to the individual E-621 modules, so no additional wiring is required. Only an additional 10 ms internal bus communications time is required to reach any of the units behind the one actually connected to the host PC. PI General Command Set The E-621 is to a large extent freely programmable and its command structure conforms to the PI General Command Set. This command set is common to the E-516 Piezo Interface and Display Module (see p. 6-58) and an increasing number of PI controllers. All new controllers for motors and actuators will understand these commands, either directly or via command libraries. This will greatly reduce the effort required to produce custom programs, especially in environments which include a number of different controllers. Included with the E-621 is userinterface software as well LabView and other driver sets.
