Description The KBMG are ultracompact, full-wave regenerative drives capable of operating DC PM or Shunt motors in a bidirectional mode. Its (4) quadrant operation provides forward and reverse torque in both speed directions. This allows the control to maintain constant speed with overhauling loads and provides rapid reversing and controlled braking. Because of its excellent controllability and response time, the KBMG can replace servos in many applications. The control is factory set for armature feedback, which provides up to 1% load regulation over a motor base speed of 50:1. Tachgenerator feedback is also provided for superior load regulation if required. A simple jumper setting converts the KBMG to a torque control. In this mode, motor torque rather than motor speed is controlled. An important feature of the drive is the factory-calibrated, built-in, selectable motor current jumper. It eliminates the need to recalibrate IR Comp and Current Limit for most applications. The control contains an Enable function that can be used to start and stop the motor electronically via a contact closure. Through a jumper selection, the motor can be controlled to rapidly “regenerate to stop” or to “coast to stop.” KB’s exclusive Auto Inhibit® circuit provides safe, smooth starting even during rapid cycling of the AC line. The Overspeed Protect Circuit prevents failure of the power bridge in extreme overhauling conditions. Reliability of the KBMG is further enhanced with the use of a high speed current limit circuit and MOV transient protection. LED’s, which can be used for diagnostics, are provided for power on and motor overload. A rugged extruded aluminum heat sink ensures enhanced heat transfer, which provides a higher control rating while maintaining cooler running SCR’s. The KBMG contains a finger-safe cover to meet the IP-20 Standard. Power connections to the KBMG are made via quick connect terminals and signal input connections are made via a removable barrier terminal block. A 5k remote potentiometer and full operating instructions are supplied.RatingsManufacturerKB Electronics (Nidec)Part Number8831Model NumberKBMG-212DAC Line Voltage115/208-230 VAC +/-10%Single Phase50/60HzMotor Voltage0 to +/-90VDC @ 115VAC Line0 to +/-180VDC @ 230VAC LineMaximum Rating Without Heat Sink12.0 AMP AC Line Current8.0 Amps DC Load Current0.75HP (0.6kW) @ 115VAC Line1.5HP (1.1kW) @ 208/230VAC LineMaximum Rating with Auxiliary Heat Sink16.0 AMP AC Line Current11.0 Amps DC Load Current1.0HP (0.75kW) @ 115VAC Line2.0HP (1.5kW) @ 208/230VAC LineSpecificationsAC Line Input Voltage115 or 208/230VAC +/-10%AC Line Frequency50/60HzArmature Voltage Range0 to +/-90VDC @ 115VAC Line0 to +/-90VDC / 0 to +/-180VDC @ 230VAC LineField Voltage100/50VDC @ 115VAC Line200/100VDC @ 230VAC LineMaximum Load Capacity150% for 2 MinutesAmbient Temperature Operating Range0 to 50°CSpeed Range50:1 RatioArmature Feedback Load Regulation+/-1% of Base SpeedTach-Generator Feedback Load Regulation+/-1% of Base SpeedAC Line Regulation+/-1% of Set SpeedCurrent Ranges1.7 Amps DC2.5 Amps DC5.0 Amps DC7.5 Amps DC10 Amps DCForward/Reverse Acceleration Range0.1 to 15 SecondsDead Band Range0 to +/-5% of Base SpeedMax Speed Trimpot Range55 to 110% of Base SpeedIR Compensation Range0 to 20VDC Full Load @ 115VAC Line0 to 40VDC Full Load @ 230VAC LineForward/Reverse Range0 to 175% Range SettingVoltage Following Input Range0 to +/-10 VDC0 to +/-15 VDCVoltage Following Linearity+/-0.5% Base SpeedFeatures Full-Wave 4 Quadrant IP20 SCR Bidirectional Variable Speed and Torque Control for PM and DC Shunt Motors Jumper Selectable Features:Operation Mode: Speed, TorqueAC Line Voltage (VAC – 50/60 Hz): 115, 230DC Armature Voltage (VDC): 90, 180Tach-generator Voltage (VDC/1000 RPM): 7, 50DC Current Output Ranges (ADC): (1.7 – 10)Analog Input Voltage (VDC): 0 to ±10, 0 to ±15Enable: Coast to Stop (CTS), Regenerate to Stop (RTS) Trimpot Adjustments:Dead Band (DB)Response (RESP)IR Compensation (IR)Forward Current Limit (FCL)Reverse Current Limit (RCL)Maximum Speed (MAX)Forward Acceleration (FACC)Reverse Acceleration (RACC) LEDs:Power On (PWR ON)Overload (OL)
