EM-366-SBL BRUSHLESS DC-MOTOR DRIVER 12-48V 30/25A POSITIONING and MODBUS
EM-366-SBL 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 reset/homing, disable, local/bus and safety stop. There is analog input for position set . EM-366-SBL has PNP output for fault indication use. Some input and output ports and functions can be set and change with parameters. Alternatively this driver can be also controlled via Rs-485 control bus with Modbus protocol.
Driver includes overvoltage, undervoltage and overtemperature protections. These fault situations are indicated with fault on-board LED. Current limit situations can be reset with reset input, reset-timer or by setting analog speed control to value to 0.
This version of EM-366 uses motor feedback pulses also for positioning, little like in servo system. The positioning resolution depends on the numbers of motor poles. for example 1-pole-pari motor 6-positon in round and 7-pole-pair motor 42 position in round.and this round means motor shaft rounds, so with gearbox the resolution can be improved. Driver has own positioning amplifier and with this can be easily adjusted dynamic and accuracy of system. Driver has also RS-485 bus with Modbus control protcol, this make flexible use and control many driver in system.
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. Parameter setting and monitoring can be also done via Rs-485 bus.
Device can be installed in DIN-rail base and some enclosure options are also available.
