EM-324-SPF is a positioning driver to be used with DC-motors. The solid state power stage operates with high efficiency and as its
realized with FET-transistors. Its literally everlasting compared to relay solutions. Feedback is done with one or two line pulse signal.
Although position feedback can be done with one pulse line it is always preferred and more secure to do it with two 0°/90° pulse lines.
This driver includes an analog control with three signal ranges, 0-5,5V, 0-11V or 4-20mA. Input is freely scalable inside the range.
The max. electrical accuracy of the driver and feedback is 0.2% which is adequate for most actuator positioning applications.
The settings and adjustments are done with parameters as in all new generation Electromen products. Included in the parameters
is also the learn routine which will help to determine the full movement range fast and easily. Additively the movement range can be
modified from both ends with SW-limit parameters. Possible cumulating pulse count errors can be avoided with manually or automatically
triggerable home drive. Current limits and driving speeds can be set individually for both directions. Driver includes also many other
dynamic adjustment features like parameter for load compensation, dead-zone setting (positioning window), start and stop ramps for
smooth direction change and braking zone for well operating positioning.
The parameter setting and status monitoring is done with EM-236 Interface Unit. With EM-236 the right parameters can also be
copied easily to other driver units. The on-board LED-light indicates the possible fault situations with blinking codes. If needed,
the fault alarm can be also given out trough combiport (pin. 13). This port can be set as "position OK." output or it can work as
an analog position signal output. Additively it can work also as disable input. Device is EMC tested for industrial and household
environment and operating temperature range is quite wide. There are also same housing options available for EM-324-SPF
driver card as for the standard EM-324.
