EM-324-SAF is a positioning driver to be used with DC-motors. The solid state power stage operates with high efficiency as it is
realized with FET-transistors. Its literally everlasting compared to relay solutions. Control and feedback is done with analog signal.
Control signal can be a voltage in range of 0 to 11V or current from 0 to 20mA. Feedback signal can be in the range from 0 to 11V.
Driver supports also a potentiometer feedback, with auxiliary voltage outputs of 0V and 5,5V to exitate the potentiometer.
The max. accuracy available for positioningof is 0,2% that is adequate for most actuator positioning applications.
The settings and adjustments are done with parameters as in all new generation Electromen products. Movement range can be
modified from both ends with SW-limit parameters. Current limits and driving speeds can be set individually for both directions.
Driver includes also many other dynamic adjustment possibilities like parameters for load compensation, dead-zone setting
(positioning window), start and stop ramps for a 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
easily copied to other driver units. The on-board LED-light indicates the possible fault situations with blinking codes. If needed,
the fault can be forwarded trough combiport to other driver cards. Alternatively this port can be set to give out the "position OK"
information or it can even indicate the position with an analog voltage signal. Device is EMC tested for industrial and household
environment and operating temperature range is quite wide.
