Electromen - EM-165pf DC motor positioning drive 12-32 V dc, 5 A, pulse FB
EM-165pf is a positioning driver for pulse feedback systems. Potentiometer or direct voltage signal can
be used as control value. The device has inbuild up-down counter and servo amplifier for positioning.
There are four counter ranges: 128, 256, 512 and 1024 pulses. Additionally the range can be fine-tuned.
The power stage of the unit is capable of directly driving a DC-motor. EM-165pf is suitable for example
driving a spindle motor equipped with pulse transducer. EM-165pf is best suited for slow and medium
speed systems with transitional period of 4...50s (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 50s 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 or by switching power off and back on.
Every time the unit is switched on, it will first drive the mechanism to one end and reset the counter. After this
it will drive the mechanism to control value. Every time the unit receives new control value, it starts the motor
and begins to compare the counter value with control value. When these two start to approach each other, the
controller slows down and finally stops when the values are indentical. Besides using one of the pulse ranges,
the positioning range can be fine tuned with control value range trim. EM-165pf is small in size and can be
mounted into a rail using a rail mounting base or screws. The unit has a self recovery overload protection and
short circuit protection. However the use of an external fuse is recommended.
