Robust Liberty MDrive® Pulse /Direction products integrate 1.8° 2-phase stepper motors with onboard control electronics and hMT closed loop performance. Products have 4 modes of operation: pulse/direction input, variable speed control, constant velocity drive, and variable torque control. |
Communications interface The LMDxP uses an isolated RS-422/485 communication interface with selectable BAUD rate ranging from 4.8 to 115 kilobits per second via a standard 9-pin D-subminiature connector. An optional USB to RS-422/485 Comm converter with cable is available and is compatible with all 32 and 64 bit operating systems. Power and I/O DC power and the I/O are interfaced via robust locking connectors: a 2-pin screw lock connector for power, and a pair of 7-pin spring-clamp terminal blocks with side-locking tabs for I/O. The isolated I/O bank consists of +5 to +24 VDC inputs for step, direction and bridge enable/disable, one (1) 5.5 mA Attention output, a 12-bit analog input and six TTL level differential encoder outputs, which are not isolated. The clock and direction inputs may be programmable to multiple clock types in software, either pulse/direction, quadrature or CW/CCW. Selectable modes of operation Unlike traditional pulse/direction devices, the Liberty MDrive Pulse/direction input may be configured to operate in the following modes of operation:
Software The Liberty MDrive Pulse/direction uses the powerful, yet easy to use Pulse/direction Configuration Utility which is part of the Liberty MDrive Software Suite. The Pulse/direction Configuration Utility is used to set all the available parameters of the LMDxP and can be used in either basic or advanced modes. Basic, for standard pulse/direction functionality with basic parameters, or Advanced, for configuring hMTecnology and advanced operating modes. |
