- 1. Analog Servo Drive ZBE12A8 Description Power Range Peak Current 12 A Continuous Current 6 A Supply Voltage 20 - 80 VDC The ZBE12A8 PWM servo drive is designed to drive brushless DC motors at a high switching frequency. The drive is fully protected against over-voltage, under-voltage, over-current, over-heating, and short-circuits at the output. A single digital output indicates operating status. This drive can interface with any controller that has analog ±10V output and may be powered by a single unregulated and isolated DC power supply.

Maximum duration of peak current is ~2 seconds. 2. Low inductance motors, such as ‘pancake’ and ‘basket-wound’, require external inductors. The Minimum Load Inductance provided assumes the highest allowed bus voltage. Lower inductances are acceptable for lower bus voltages. 3. Additional cooling and/or heatsink may be required to achieve rated performance.
