EM-366A is brushless DC-motor driver with hall sensor feedback. The unit has a mosfet power stage with good efficiency and it meets also 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, this voltage rising can be controlled with braking resistor. If uses battery supply then the braking energy can be leaded back to battery and braking resistor will not needed.
The unit has the basic digital command inputs like direction, start/stop, disable, speed-2 activation and there is analog inputs for speed and current control. EM-366A has PNP output for fault indication use. Several 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 and indication output. In -A version has new shutdown input for disabling power stage and same time it reduces the. Optionally this device can be controlled with Rs-485 interface with modbus
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 ramps can be set with parameter. Analog input are filtered so that there can also use 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-328 adapter cable. Parameters stored into nonvolatile memory of device. This interface unit can also be monitored the current and rpm of motor.
Device can be installed in DIN-rail base and some enclosure options are also available
