EM-165 POSITIONING DRIVER 12-32Vdc FEATURES • small in size • low cost • pos. accuracy. typ. ±1% • good effeciency >92% • for motors 5-200W • start- and stop-ramp • overload protected • selectable current limit • rail base mountable EM-165 is a low cost positioning driver. It has an inbuilt servo amplifier and a power stage for controling a dc-motor. It is suitable for driving a spindle motor equipped with feedback potentiometer. EM-165 is best suited for slow and medium speed systems with a transitional period of 2...30s (from end to end). The current limit is settable and can be used to limit the torque of the motor. Current trip feature will shut down the driver in fault situation, if either current is on the limit for over 2s, or if it takes more than 30s to reach the set value. In fault situation the error output will be activated. Reactivation from the trip situation is done by applying a reverse control command. Positioning is done by giving a new set value using the set value potentiometer or voltage signal 0-5V. The driver compares the feedback value to the set value and starts to drive the motor towards the set value. When these values begin to approach each other, the driver will slow down, and when the values are identical the motor stops. EM-165 is small sized and easy to install. It is possible to use screw fastening or install the driver in to a rail with a rail mounting base which is available as an accessory. The power stage is equipped with self recovery overload and over current protection, but the use of an external fuse is recommended.

OPERATING INSTRUCTIONS EM-165 IMPORTANT ! Supply voltage must be filtered 12-32 VDC with less than 20% ripple. Choose the fuse according to the application ( max. 15A ). Check the polarity before connecting. 2.5mm 26mm 2.5mm SETTING MAP 5 6 7 8 9 2A - without I-trip 4A - without I-trip SETTINGS 7A - without I-trip CURRENT TRIP ( DRIVE SHUT DOWN ) The current trip function is activated with jumper named "I-trip". If current trip is activated the driver will be shut down and the error output will appear in the following cases: - overcurrent situation for over 2s - positioning takes longer...
