Opis produktu

EM-347 is brushless DC-motor driver with hall sensor feedback. The unit has a mosfet power stage with good efficiency and it also

meets todays EMC requirements. The driver can be used with 120° commutation. This driver has true 4Q power stage, and it makes

possible to use regenerative braking. In this braking method the supply voltage rises at braking. The voltage rising can be controlled

with braking resistor. If uses battery supply then the braking energy can be leaded back to the battery and braking resistor will not be required.

The unit has the basic digital command inputs like direction, brake, start/stop, disable and there is analog inputs for speed and current control. One digitally presetable second speed (speed-2) is possible to activate with digital command input. EM-347 has two NPN outputs for fault and overcurrent indication use. Some input and output functions can be modified with parameters.

Driver includes overvoltage, undervoltage and overtemperature protections. These fault situations are indicated with fault on-board LED.

Overtemperature and current limit situations can be reset with reset input, reset-timer or by setting analog speed control to value to 0.

There are two control options for speed. Direct control ( open loop ) sets motor voltage in propotion to control voltage as with a standard DC-motor. Closed loop uses hall sensor feedback for speed control, this mode offers good speed regulation.

Start and stop ramps work in both mode. Speed adjust range, closed loop rpm range and rampse can be set with parameter.

Analog input are filtered so that there can used also PWM signal for control speed and current.

Setting can be done digitally with EM-236 interface unit or with Emen-Tool lite program installed in PC and EM-268 or EM-328

adapter cable. Parameters stored into nonvolatile memory of device. This interface unit can also be monitored the current and

rpm of motor. Device has also output for cooling fan, it can be controlled optional fan if needed.

This output switch on fan, when temperature rises over 65 deg.

Device can be installed in DIN-rail base and some enclosure options are also available.
